FIG. 1 is a conceptual diagram illustrating the relation between an electronic device 100, a first external electronic device 110, and a second external electronic device 120. FIG. 1 illustrates the electronic device 100, the first external electronic device 110, and the second external electronic device 120. The first external electronic device 110 may be an electronic device (for example, a predetermined suitable electronic device such as a server or a computer) of a fintech company providing fintech services. The second external electronic device 120 may be an electronic device (for example, a predetermined suitable electronic device such as a server or a computer) of a financial institution operating a financial system to provide various financial services. The electronic device 100 may be a predetermined suitable electronic device such as a server or a computer which may generate an API, manage the generated API, and electrically communicate with the first external electronic device 110 and the second external electronic device 120.

According to various embodiments of the present disclosure, the electronic device 100 may be connected to financial systems of various financial institutions and may provide open banking platforms for providing financial services and/or financial functions provided by the various financial institutions. For example, the electronic device 100 may construct and provide an open banking website through which customers of various financial institutions access and use financial services. Further, when fintech companies develop fintech services, the electronic device 100 allows the fintech companies to use various APIs for financial services and/or functions provided by the various financial institutions. In addition, the electronic device 100 not only allows the fintech companies to simply and manually use pre-generated APIs but also combines APIs or generates APIs according to demands of the fintech companies and allows the fintech companies to use the combined or generated APIs, thereby enabling the fintech companies to more easily develop fintech services.

According to various embodiments of the present disclosure, the electronic device 100 may store a plurality of pre-generated first APIs. For example, each of the plurality of first APIs may be an API related to each of a plurality of financial services (for example, a remitter identification service, a remittee identification service, a domestic and international remittance service, an exchange service, and an account name identification service, etc.) which can be performed by the second external electronic device 120. One first API may be associated with a plurality of financial services or with some steps, procedures, and modules of one financial service. The electronic device 100 may allow the second external electronic device 120 to provide a plurality of financial services through the plurality of first APIs. Further, in order to make the fintech company more easily implement fintech services (for example, an international remittance service, a P2P loan service, and an exchange service, etc.) through at least one of a plurality of financial services provided by the second external electronic device 120, the electronic device 100 may allow the first external electronic device 110 of the fintech company to use at least one of the plurality of first APIs.

According to various embodiments of the present disclosure, the electronic device 100 may combine a plurality of second APIs selected by the first external electronic device 110 from the plurality of first APIs to generate a third API and allow the first external electronic device 110 to use the third API. Accordingly, even though the fintech company does not know how to use a financial service related to the fintech service to be implemented in the total financial system, the electronic device 100 may allow the fintech company to easily implement the fintech service. Further, by generating the third API by itself through the combination of the plurality of second APIs, the electronic device 100 may combine a plurality of financial services corresponding to the plurality of second APIs and provide the same to the first external electronic device 110 even though the financial system operated by the second external electronic device 120 is not modified or adjusted.

According to various embodiments of the present disclosure, when at least one API corresponding to at least one financial service required for the fintech service which the fintech company desires to implement does not exist in the plurality of pre-generated first APIs, the first external electronic device 110 may make a request for generating a new API corresponding to at least one financial service to the electronic device 100. The electronic device 100 may generate a new API according to a request from the first external electronic device 110 and allow the first external electronic device 110 to use the generated new API. As described above, the electronic device 100 may directly generate an API suitable for the fintech service which the fintech company desires to implement according to a request from the fintech company and allow the fintech company to use the API, so that the development load of the fintech service generated during a process in which the fintech company implements the fintech service may be reduced.

Although FIG. 1 illustrates only one first external electronic device 110, it is not limited thereto, and the electronic device 100 may allow each of a plurality of first external electronic devices 110 of one or more fintech companies to use at least one of a plurality of first APIs. Although FIG. 1 illustrates only one second external electronic device 120, it is not limited thereto, and the electronic device 100 may pre-generate and store a plurality of first APIs associated with a plurality of financial services which can be provided by a plurality of second external electronic devices 120 of one or more financial institutions and allow each of the plurality of second external electronic devices 120 to provide the plurality of financial services through the plurality of first APIs. The electronic device 100 may be included in the second external electronic device 120 or may be an element separate from the second external electronic device 120.

FIG. 2 is a block diagram illustrating the configuration of the electronic device 100 according to various embodiments of the present disclosure. According to various embodiments of the present disclosure, the electronic device 100 may include a memory 210, a communication circuit 220, and a processor 230. A plurality of elements included in the electronic device 100 may be electrically connected through a bus (not shown) to transmit information, control, instructions, and data, etc.

According to an embodiment, the memory 210 may store instructions related to at least one other element of the electronic device 100. Further, the memory 210 may store software and/or programs. For example, the memory 210 may include an internal memory or external memory. The internal memory may include at least one of volatile memory (for example, DRAM, SRAM, or SDRAM) and non-volatile memory (for example, flash memory, hard drive, or Solid State Drive (SSD)). The external memory may be functionally or physically connected to the electronic device 100 through various interfaces.

According to an embodiment, the memory 210 may store instructions for operating the processor 230. For example, the memory 210 may store instructions causing the processor 230 to control other elements of the electronic device 100 or to interwork with an external electronic device or an external server. Further, instructions for performing the operation by each element may be stored in the memory 210. The processor 230 may control other elements of the electronic device 100 based on the instructions stored in the memory 210 and interwork with an external electronic device or an external server. Hereinafter, the operation of the electronic device 100 will be described on the basis of each element of the electronic device 100.

According to an embodiment, the communication circuit 220 may communicate with an external electronic device or an external server. For example, the communication circuit 220 may establish communication between the electronic device 100 and external electronic devices, for example, the first external electronic device 110 and the second external electronic device 120. The communication circuit 220 may be connected to a network through wireless communication or wired communication to communicate with the external electronic device and the external server. In another example, the communication circuit 220 may be connected to the external electronic device through a wire to communicate with the external electronic device.

Wireless communication may include, for example, cellular communication (for example, LTE, LTE-Advanced (LTE-A), Code Division Multiple Access (CDMA), Wideband CDMA (WCDMA), Universal Mobile Telecommunications System (UMTS), and Wireless Broadband (WiBro)). Further, wireless communication may include short-range wireless communication (for example, Wireless Fidelity (Wi-Fi), Light Fidelity (Li-Fi), Bluetooth, Bluetooth Low Energy (BLE), ZigBee, and Near Field Communication (NFC)).

According to an embodiment, the processor 230 may execute an operating system or an application to control at least one element of the electronic device 100 and perform various data processing and calculations. For example, the processor 230 may include a central processing unit and may be implemented as a System on Chip (SoC).

According to an embodiment, the memory 210 may store a plurality of pre-generated first APIs. For example, the plurality of first APIs may be associated with each of a plurality of financial services which can be performed by the second external electronic device 120. One of the plurality of first APIs may be associated with a plurality of financial services, or one or a plurality of first APIs may be associated with some steps, procedures, and modules of one financial service. Further, the memory 210 may further store a plurality of modules used for generating the API. For example, each of the plurality of modules may be associated with each of a plurality of financial functions which can be performed by the second external electronic device 120 or some steps or procedures of the plurality of financial functions. The plurality of first APIs may be generated by the processor 230 through the plurality of modules. A detailed method for generating the plurality of first APIs through the plurality of modules stored in the memory 210 will be described below.

Further, the memory 210 may store an API list including the plurality of first APIs. For example, the API list may include a name of each of the first APIs, access information (for example, a URL, etc.) for access to each of the plurality of APIs, information on a financial service corresponding to each of the plurality of first APIs, and input and output of each of the plurality of first APIs, etc.

According to an embodiment, the processor 230 may transmit the API list to the first external electronic device 110 through the communication circuit 220 according to a request of providing the API list received from the first external electronic device 110. Thereafter, the processor 230 may generate a third API by combining a second APIs based on a request of using the plurality of second APIs received from the first external electronic device 110 and allow the first external electronic device 110 to use the third API. Further, the processor 230 may generate a new API (hereinafter, referred to as a fourth API) based on a request of generating the new API received from the first external electronic device 110 and allow the first external electronic device 110 to use the new API. In addition, the processor 230 may generate a third API by combining the new API and the plurality of second APIs and allow the first external electronic device 110 to use the third API. A detailed operation of the processor 230 will be described below.

FIG. 3 is a flowchart illustrating a method for providing APIs by the electronic device according to various embodiments of the present disclosure. In step 310, when the electronic device 100 receives a request for providing an API list from the first external electronic device 110, the electronic device 100 may transmit the API list stored in the memory 210 to the first external electronic device 110. In order to identify APIs which may be usable by the electronic device 100, the first external electronic device 110 may make a request for providing an API list to the electronic device 100. In response to reception of the request for providing the API list through the communication circuit 220, the processor 230 of the electronic device 100 may search for the API list stored in the memory 210 and control the communication circuit 220 to transmit the searched API list to the first external electronic device 110.

The API list transmitted to the first external electronic device 110 may be provided to a user of the first external electronic device 110 (for example, a developer, an operator of the fintech company, etc.). For example, the API list may be displayed on a display device of the first external electronic device 110 and provided to the user. The user of the first external electronic device 110 may select a plurality of second APIs from the plurality of first APIs included in the API list. The plurality of second APIs may be APIs corresponding to one or a plurality of financial services required by a fintech service which the user of the first external electronic device 110 desires to implement. Further, the user of the first external electronic device 110 may designate a selection order of the plurality of second APIs. The first external electronic device 110 may receive input for selecting the plurality of second APIS from the plurality of first APIs and orders of the selection from the user through an input interface (for example, a touch screen, a mouse, and a keyboard, etc.).

In step 320, when a request for using the plurality of second APIs is received from the first external electronic device 110, the electronic device 100 may generate a third API by combining the plurality of second APIs stored in the memory 210. For example, the processor 230 may receive the request for using the plurality of second APIs selected from the plurality of first APIs included in the API list from the first external electronic device 110 through the communication circuit 220. The request for using the plurality of second APIs may include, for example, information on the plurality of second APIs and selection order information indicating the selection order of each of the plurality of second APIs selected by the user of the first external electronic device 110.

When the request for using the plurality of second APIs is received, the processor 230 of the electronic device 100 may generate a third API by combining the plurality of second APIs stored in the memory 210. Since a method for generating one API by combining a plurality of APIs is obvious to those skilled in the art, a detailed description thereof will be omitted.

The processor 230 may identify the selection order of each of the plurality of second APIs through selection order information included in the request of using the plurality of second APIs. The processor 230 may generate a third API by sequentially combining the plurality of second APIs according to the identified selection order of each of the plurality of second APIs.

According to an embodiment, the processor 230 may generate a third API by combining the plurality of second APIs based on characteristics of the financial service corresponding to each of the plurality of second APIs. For example, when the plurality of second APIs includes API "A" and API "B" and it is determined to provide financial service "B" earlier than financial service "A" according to characteristics of financial service "A" corresponding to API "A" and financial service "B" corresponding to API "B", the processor 230 may generate a third API by sequentially combining API "B" and API "A" even though API "A" is selected earlier than API "B".

According to an embodiment, after generating the third API, the processor 230 may control the communication circuit 220 to transmit access information for accessing the third API and a message indicating completion of the generation of the third API. The first external electronic device 110 may use the API by accessing the API through the access information for access to the API. Accordingly, the processor 230 may transmit the access information for access to the third API to the first external electronic device 110 through the communication circuit 220 to allow the first external electronic device 110 to use the third API. Further, the processor 230 may transmit a message through the communication circuit 220 in order to inform the user of the first external electronic device 110 of the completion of the generation of the third API.

According to an embodiment, after generating the third API, the processor 230 may update the API list to include the third API and store the updated API list in the memory 210. For example, the processor 230 may update the API list by adding the third API to the API list, thereby allowing other fintech companies to use the third API included in the updated API list for implementing fintech services later.

In step 330, the electronic device 100 may generate an approval key required for processing process-requested data using the third API. The approval key may indicate a right to use the third API, and the processor 230 may generate the approval key to assign the right to use the third API to the first external electronic device 110. When the approval key along with process-requested data have not been received, the processor 230 of the electronic device 100 may reject processing of the process-requested data using the third API.

According to an embodiment, upon receiving the request of using the third API from the first external electronic device 110, the processor 230 of the electronic device 100 may generate the approval key. According to another embodiment, the processor 230 may generate the approval key in advance after generating the third API even though there is no separate request of the use from the first external electronic device 110. In this case, the processor 230 may maintain the approval key generated in advance in an inactive state until the request for the use is received from the first external electronic device 110, and when receiving the request for the use from the first external electronic device 110, switch the approval key to an active state.

In step 340, the electronic device 100 may transmit the generated approval key to the first external electronic device 110. For example, the processor 230 may control the communication circuit 220 to transmit the generated approval key to the first external electronic device 110. Further, when the generated approval key is in the inactive state and the processor 230 receives the request for the use from the first external electronic device 110, the processor 230 may switch the approval key to the active state and then control the communication circuit 220 to transmit the approval key to the first external electronic device 110.

As described above, the electronic device 100 enables the first external electronic device 110 to use one API generated by combining the plurality of APIs associated with the financial service required by the fintech service which the user of the first external electronic device 110 desires to implement, so that the fintech company may easily implement the fintech service including the financial service and reduce development burden in a process of implementing the fintech service.

first APIs

411, 412, 413, 414, and 415, the API list 400 may include an API name 401, access information 402 for accessing the API, and financial service information 403 corresponding to the API. Upon receiving the API list 400 from the electronic device 100, the first external electronic device 110 may display the received API list 400 through a display device (not shown) of the first external electronic device 110. For example, the first external electronic device 110 may display the API list 400 in a webpage form. However, this is only for description and is not limited thereto. The first external electronic device 110 may display the API list 400 through a display device in various ways in order to allow the user to identify the API list 400.

Further, the API list 400 may further include detailed information 420 on each of the plurality of

first APIs

411, 412, 413, 414, and 415. As illustrated in FIG. 4B, the detailed information 420 may be displayed through the display device of the first external electronic device 110 according to input of the user of the first external electronic device 110. For example, when the user of the first external electronic device 110 desires to know detailed information on the first API 412 and selects the first API 412 through an input interface (for example, a touch screen, a mouse, or a keyboard, etc.) of the first external electronic device 110, the first external electronic device 110 may display detailed information 420 corresponding to the first API 412 through the display device. As illustrated in FIG. 4B, the detailed information 420 corresponding to the first API 412 may include detailed information on the first API 412 according to items such as an API name, access information, financial service information corresponding to the API, and an API authentication scheme. However, this is only for description but is not limited thereto. The detailed information 420 corresponding to the first API 412 may include detailed information on the first API 412 according to items other than the items illustrated in FIG. 4B. The user of the first external electronic device 110 may identify the detailed information 420 corresponding to the first API 412 and thus determine whether the first API 412 is necessary for the financial service required by the fintech service. When it is determined that the first API 412 is necessary, the user of the first external electronic device 110 may select the first API 412 as one of a plurality of second APIs for which the request to use the same is transmitted to the electronic device 100 through the input interface of the first external electronic device 110.

FIG. 5 is a conceptual diagram illustrating a method for generating a third API by combining a plurality of second APIs according to various embodiments of the present disclosure. According to various embodiments of the present disclosure, the processor 230 of the electronic device 100 may receive a request for using a plurality of

second APIs

511, 512, and 513 selected from a plurality of first APIs 510 from the first external electronic device 110 through the communication circuit 220 of the electronic device 100. For example, the request for using the plurality of

second APIs

511, 512, and 513 may include information on the plurality of

second APIs

511, 512, and 513 and selection order information indicating the selection order of each of the plurality of

second APIs

511, 512, and 513 selected by the user of the first external electronic device 110.

According to an embodiment, information on the plurality of

second APIs

511, 512, and 513 may be information by which the electronic device 100 identifies each of the plurality of

second APIs

511, 512, and 513. In order to generate a third API 520 by combining the plurality of

second APIs

511, 512, and 513, the electronic device 100 is required to identify the plurality of

second APIs

511, 512, and 513 selected by the user of the first external electronic device 110, so that the first external electronic device 110 may transmit information for identifying each of the plurality of

second APIs

511, 512, and 513 to the electronic device 100. For example, the processor 230 may identify API #2 511, API #7 512, and API #4 513 among the plurality of first APIs based on information on the plurality of

second APIs

511, 512, and 513.

According to an embodiment, selection order information indicating the selection order of each of the plurality of

second APIs

511, 512, and 513 may be information indicating when each of the plurality of

second APIs

511, 512, and 513 is selected by the user of the first external electronic device 110. For example, when the user of the first external electronic device 110 sequentially selects API #2 511, API #7 512, and API #4 513, the selection order information may be configured such that the processor 230 may identify that API #2 511 is selected first, API #7 512 is selected second, and API #4 513 is selected third.

According to an embodiment, the processor 230 may generate a third API 520 by combining the plurality of

second APIs

511, 512, and 513. The processor 230 may identify characteristics of the financial service corresponding to each of the plurality of

second APIs

511, 512, and 513 in order to generate the third API 520. The processor 230 may identify whether at least one of a plurality of data processed using the plurality of

second APIs

511, 512, and 513 is needed to be processed together with the processing result of other data based on characteristics of the financial service corresponding to each of the plurality of

second APIs

511, 512, and 513.

According to an embodiment, when it is determined that the plurality of data processed using the plurality of

second APIs

511, 512, and 513 is not needed to be processed together with the processing result of other data, in other words, when it is determined that each of a plurality of data may be processed independently from each other, the processor 230 may combine the plurality of

second APIs

511, 512, and 513 in a random order and generate the third API 520 to independently process data.

According to an embodiment, when it is determined that at least one of the plurality of data processed using the plurality of

second APIs

511, 512, and 513 is needed to be processed together with the processing result of other data, the processor 230 may determine a processing order of each of the plurality of data based on at least one of the selection order of each of the plurality of

second APIs

511, 512, and 513 or the characteristics of the financial service corresponding to each of the plurality of

second APIs

511, 512, and 513.

For example, the processor 230 may identify that the user of the first external electronic device 110 sequentially selects API #2 511, API #7 512, and API #4 513 according to the selection order information. The processor 230 may determine that the plurality of data is processed in an order of data a processed using API #2 511, data b processed using API #7 512, and data c processed using API #4 513 according to the identified selection order.

In another example, even though the user of the first external electronic device 110 selects the APIs in the order of API #2 511, API #7 512, and API #4 513, the processor 230 may determine the processing order of each of the plurality of data such that data b and data c are processed in preference to data a due to the characteristics of the financial service corresponding to each of the plurality of

second APIs

511, 512, and 513. For example, it is assumed that the financial service corresponding to API #2 511 is a fund transfer service, the financial service corresponding to API #7 513 is a remitter identification service, and the financial service corresponding to API #4 512 is a remittee identification service. In this case, even though the user of the first external electronic device 110 selects the APIs in an order of API #2 511, API #7 513, and API #4 512, the financial services corresponding to API #7 512 and API #4 513 should be provided earlier than the financial service corresponding to API #2 511, so that the processing order of each of the plurality of data may be determined such that data b and data c are processed in preference to data a. Further, the processing order of each of the plurality of data may be determined such that data b is processed in preference to data c according to the selection order by the user of the first external electronic device 110 or may be determined such that data c is processed in preference to data b regardless of the selection order by the user of the first external electronic device 110. In other words, the processor 230 may determine the processing order of each of the plurality of data such that the data is processed in an order of data b, data c, data a, or data c, data b, and data a.

According to an embodiment, the processor 230 may generate the third API 520 by sequentially combining the plurality of

second APIs

511, 512, and 513 based on the determined processing order of each of the plurality of data. However, this is only for description but is not limited thereto. The processor 230 may generate the third API 520 to process data according to the determined processing order of each of the plurality of data even though the plurality of

second APIs

511, 512, and 513 are not sequentially combined based on the processing order of each of the plurality of data.

For example, the processor 230 may determine a combination order of each of the plurality of

second APIs

511, 512, and 513 based on the processing order of each of the plurality of data and sequentially combine the plurality of second APIs according to the determined combination order of each of the plurality of

second APIs

511, 512, and 513 so as to generate the third API 520. For example, the processor 230 may generate the third API 520 by sequentially combining API #2 511, API #7 512, and API #4 513 according to the selection order by the user of the first external electronic device 110. In another example, the processor 230 may generate the third API 520 by sequentially combining API #7 API 512, API #4 513, and API #2 511 based on the selection order by the user of the first external electronic device 110 and characteristics of the financial service corresponding to each of the plurality of

second APIs

511, 512, and 513. In still another example, the processor 230 may generate the third API 520 by sequentially combining API #7 API 512, API #4 513, and API #2 511 or API #4 513, API #7 512, and API #2 511 based on characteristics of the financial service corresponding to each of the plurality of

second APIs

511, 512, and 513.

FIG. 6 illustrates a screen for displaying a list of a plurality of second APIs included in a third API according to various embodiments of the present disclosure. According to various embodiments of the present disclosure, after generating the third API, the processor 230 of the electronic device 100 may transmit a list of a plurality of second APIs included in the third API or information on the third API including a list of one or more second APIs and a fourth API (that is, a newly generated API) to the first external electronic device 110. In order to allow the user of the first external electronic device 110 to identify whether the third API is generated as intended by the user, the processor 230 may control the communication circuit 220 to transmit information on the third API to the first external electronic device 110.

Referring to FIG. 6, the information on the third API may include a list of a plurality of second APIs including, for example, API #2, API #7, and API #4. Although not illustrated, the information on the third API may further include an API name for each of the plurality of second APIs, access information for access to the API, financial service information corresponding to the API, etc.

Upon receiving the information on the third API from the electronic device 100, the first external electronic device 110 may display the received information on the third API through a display device of the first external electronic device 110 in the form of a table 610. For example, the first external electronic device 110 may display the table 610 of the information on the third API in a webpage form. However, this is only for description but is not limited thereto. The first external electronic device 110 may display or output the information on the third API in various ways and forms in order to allow the user to identify the information on the third API.

FIG. 7 is a flowchart illustrating a method for processing test data according to various embodiments of the present disclosure. In step 710, after a third API is generated, the electronic device 100 may generate a test key required for a request for processing test data using the third API. For example, in order to identify whether the third API processes data as intended by the user of the first external electronic device 110, the processor 230 of the electronic device 100 is required to perform a test for processing data on the third API, so that the processor 230 may generate the test key used during a test procedure for processing data on the third API. For example, the test key indicates a temporary right to use the third API to process test data using the third API, and when the processor 230 does not receive the test key together with the test data, the processor 230 may reject processing of the test data using the third API.

In step 720, the electronic device 100 may transmit the generated test key to the first external electronic device 110. For example, the processor 230 may control the communication circuit 220 to transmit the generated test key to the first external electronic device 110. In step 722, the first external electronic device 110 may transmit the test key received from the electronic device 100 and test data for testing data processing of the third API to the electronic device 100. Before transmitting a request of using the third API to the electronic device 100, the user of the first external electronic device 110 may perform a test for data processing of the third API in order to identify whether the generated third API normally operates in the fintech service.

In step 730, the electronic device 100 may verify validity of the received test key. For example, before making a request of processing the test data using the third API to the second external electronic device 120, the processor 230 may verify validity of the test key. When it is determined that the test key is not valid, the processor 230 may reject processing of the test data.

In step 740, when the test key is valid, the electronic device 100 may transmit the test data to the second external electronic device 120 using the third API. When it is verified that the test key is valid, the processor 230 may control the communication circuit 220 to transmit the test data to the second external electronic device 120 using the third API in order to process the test data and make a request for processing the test data to the second external electronic device 120. In step 742, the second external electronic device 120 may process the test data based on the financial service corresponding to the third API and transmit a processing result of the test data to the electronic device 100.

In step 750, the electronic device 100 may transmit the processing result of the test data received from the second external electronic device 120 to the first external electronic device 110. For example, upon receiving the processing result of the test data from the second external electronic device 120, the processor 230 may control the communication circuit 220 to transmit the processing result of the test data to the first external electronic device 110. In step 760, the first external electronic device 110 may identify the processing result of the test data received from the electronic device 100. For example, the first external electronic device 110 may analyze the processing result of the test data and make a request for identifying whether the test data is processed as intended by the user of the first external electronic device 110 to the user. In step 770, when it is identified from the user that the test data is processed as intended by the user of the first external electronic device 110, the first external electronic device 110 may transmit a request for using the third API to the electronic device 100. For example, the request for the use may be a request for assigning a right for processing process-requested data using the third API.

In step 780, as the electronic device 100 receives the request for the use from the first external electronic device 110, the electronic device 100 may generate an approval key required for processing the process-requested data using the third API. The approval key may indicate a right to use the third API, and the processor 230 may generate the approval key to assign the right to use the third API to the first external electronic device 110. In step 790, the electronic device 100 may transmit the generated approval key to the first external electronic device 110. For example, the processor 230 may control the communication circuit 220 to transmit the generated approval key to the first external electronic device 110.

FIG. 8 is a flowchart illustrating a method for processing process-requested data according to various embodiments of the present disclosure. In step 810, after receiving the approval key of the third API, the first external electronic device 110 may transmit process-requested data and the approval key of the third API to the electronic device 100. For example, the process-requested data may be data processed using the third API through the second external electronic device 120. In step 820, the electronic device 100 may verify validity of the approval key received from the first external electronic device 110. For example, the processor 230 of the electronic device 100 may verify validity of the approval key before making a request for processing the process-requested data to the second external electronic device 120. When it is determined that the approval key is not valid, the processor 230 may reject processing of the process-requested data.

In step 830, the electronic device 100 may transmit the process-requested data to the second external electronic device 120 using the third API. For example, when the approval key is valid, the processor 230 may control the communication circuit 220 to transmit the process-requested data to the second external electronic device 120 using the third API and make a request for processing the process-requested data to the second external electronic device 120. In step 832, the second external electronic device 120 may process the processing request result through the financial service corresponding to the third API and transmit a processing result of the process-requested data to the electronic device 100.

In step 840, the electronic device 100 may transmit the processing result of the process-requested data received from the second external electronic device 120 to the first external electronic device 110. For example, upon receiving the processing result of the process-requested data from the second external electronic device 120, the processor 230 may control the communication circuit 220 to transmit the processing result of the process-requested data to the first external electronic device 110.

FIGs. 9A and 9B are conceptual diagrams illustrating a method for processing data using APIs according to various embodiments of the present disclosure. Although FIGs. 9A and 9B illustrate that data is input to

third APIs

910 and 920 and processed data is output from the

third APIs

910 and 920, this is only for convenience of description and data received from the first external electronic device 110 is transferred to the second external electronic device 120 using third APIs but the data is not actually input to or output from the

third APIs

910 and 920. Hereinafter, for convenience of description, it is assumed that data a is data transferred to and processed by the second external electronic device 120 using APIs #2 911 and 921, data b is data transferred to and processed by the second external electronic device 120 using APIs #7 912 and 922, and data c is data transferred to and processed by the second external electronic device 120 using APIs #4 913 and 923.

According to various embodiments of the present disclosure, the processor 230 of the electronic device 100 may independently process data using a third API 910 as illustrated in FIG. 9A. For example, the processor 230 may receive data a, data b, and data c from the first external electronic device 110. The processor 230 may independently transfer data a, data b, and data c to the second external electronic device 120 using API #2 911, API #7 912, and API #4 913, respectively, regardless of the order thereof. The processor 230 may receive data a' which is a processing result of data a, data b' which is a processing result of data b, and data c' which is a processing result of data c from the second external electronic device 120. The processor 230 may transmit data a', data b', and data c' to the first external electronic device 110. As described above, the processor 230 may independently process each of data a, data b, and data c regardless of the processing result of the other data.

According to various embodiments of the present disclosure, the processor 230 may sequentially process the data through the third API as illustrated in FIG. 9B. In FIG. 9B, for convenience of description, it is assumed that the data processing order is determined such that data b and data c are processed in preference to data a, and it is required to process data a together with the processing result of data b and data c. The processor 230 may receive data a, data b, and data c from the first external electronic device 110. Before transmitting data to the second external electronic device 120 using API #2 921, the processor 230 may transmit data b to the second external electronic device 120 using API #7 922 and data c to the second external electronic device 120 using API #4 923. The processor 230 may receive data b' which is the processing result of data b and data c' which is the processing result of data c from the second external electronic device 120. After receiving data b' and data c', the processor 230 may transmit data a, data b', and data c' to the second external electronic device 120 using API #2 921 and may receive data a' which is the processing result of data a. After receiving data a', the processor 230 may transmit data a', data b’, and data c' to the first external electronic device 110. As described above, when there is a need to process one of a plurality of pieces of data together with the processing result of other data, the processor 230 may process the data according to the determined data processing order, receive the processing result of all pieces of data from the second external electronic device 120, and then transmit the processing result to the first external electronic device 110.

As described with reference to FIGs. 9A and 9B, after receiving a plurality of pieces of data, the electronic device 100 may process all of the plurality of pieces of data and then transmit the processing result of all of the plurality of pieces of data to the first external electronic device 110 at one time rather than individually processing the data and transmitting the processing result of each of the plurality of pieces of data to the first external electronic device 110 one by one. Accordingly, the user of the first external electronic device 110 may implement a plurality of financial services required for the fintech service which the user desires to implement through one program or module and thus may more easily develop the fintech service.

FIG. 10 is a flowchart illustrating a method for generating a new API according to various embodiments of the present disclosure. In step 1010, the electronic device 100 may receive a request for generating a new API from the first external electronic device 110. When it is determined that there is no financial service suitable for the fintech service to be implemented among a plurality of financial services corresponding to a plurality of first APIs included in an API list received from the electronic device 100, the first external electronic device 110 may transmit a request for generating a new API to the electronic device 100.

In step 1020, the electronic device 100 may transmit API generation-related information stored in the memory 210 to the first external electronic device 110. According to an embodiment, the memory 210 may store API generation-related information indicating a plurality of first process-requested data to be processed using the API and a plurality of first output data to be output as the processing result using the API. The API generation-related information stored in the memory 210 may be used when the processor 230 of the electronic device 100 generates the API. For example, the processor 230 may generate an API used for transmitting at least one processing request data among the plurality of first processing request data to the second external electronic device 120 and receiving at least one output data among the plurality of first output data from the second external electronic device 120. Upon receiving the request for generating the new API from the first external electronic device 110 through the communication circuit 220, the processor 230 may control the communication circuit 220 to transmit the API generation-related information stored in the memory 210 to the first external electronic device 110. The processor 230 may transmit the API generation-related information to the first external electronic device 110 and detect process-requested data and output data which the user of the first external electronic device 110 desires, so as to generate an API corresponding to a financial service suitable for the fintech service.

In step 1030, the electronic device 100 may receive a selection request for selecting second process-requested data from among the plurality of first process-requested data and second output data from among the plurality of first output data from the first external electronic device 110. The first external electronic device 110 may display API generation-related information received from the electronic device 100. Further, in order to make a request for generating the API corresponding to the financial service suitable for the fintech service, the first external electronic device 110 may receive input for selecting second process-requested data required to be processed in the financial service suitable for the fintech service and second output data required as the processing result from the user of the first external electronic device 110. The first external electronic device 110 may transmit a selection request of selecting the second process-requested data and the second output data according to user input to the electronic device 100. For example, the selection request may include information indicating the second process-requested data and the second output data.

In step 1040, the electronic device 100 may search for at least one module associated with the second process-requested data or the second output data among a plurality of modules stored in the memory 210 based on the selection request received from the first external electronic device 110. According to an embodiment, the memory 210 may further store a plurality of modules used for API generation. For example, each of the plurality of modules may be a module associated with each of a plurality of financial functions which can be performed by the second external electronic device 120. Further, each of the plurality of modules may be associated with at least one process-requested data among the plurality of first process-requested data or at least one output data among the plurality of first output data included in the API generation-related information. For example, among the plurality of modules, a first module may be associated with process-requested data A of the plurality of pieces of first process-requested data, and output data A. Association between the first module, and process-requested data A and output data A may mean that, when process-requested data A is transmitted to the second external electronic device 120 through an API generated using the first module, the second external electronic device 120 processes process-requested data A through a financial function corresponding to the first module and outputs output data A as the processing result.

The processor 230 may identify second process-requested data and second output data according to a selection request received from the first external electronic device 110. In order to generate a fourth API for outputting the second output data as the processing result using the second process-requested data, the processor 230 may search for at least one module associated with the second process-requested data or the second output data among a plurality of modules.

In step 1050, the electronic device 100 may generate the fourth API which is a new API through at least one searched module. For example, the processor 230 may generate the fourth API by combining at least one module. The module is a lower element used for generating the API, and a method for generating the API through at least one module is obvious to those skilled in the art, so that a separate description thereof will be omitted.

FIG. 11 is a conceptual diagram illustrating a method for generating a new API according to various embodiments of the present disclosure. As illustrated in (a) of FIG. 11, the memory 210 of the electronic device 100 may store a plurality of modules 1110 used for generating an API or information on a corresponding module. Each of a plurality of modules may be a module associated with each of a plurality of financial functions. The processor 230 may search for a plurality of

modules

1120, 1121, and 1122 used for generating an API among the plurality of modules stored in the memory 210 based on a selection request received from the first external electronic device 110.

For example, each of the plurality of

modules

1120, 1121, and 1122 may be a module associated with at least one of the second process-requested data and the second output data identified through the selection request. In other words, when the second process-requested data is transmitted to the second external electronic device 120 through the generated API using the plurality of

modules

1120, 1121, and 1122, the second external electronic device 120 may process the second process-requested data through the financial function corresponding to each of the plurality of

modules

1120, 1121, and 1122 and output the second output data as the processing result.

According to an embodiment, the processor 230 may generate a fourth API 1130 which is a new API by combining the plurality of searched

modules

1120, 1121, and 1122. Further, the processor 230 may identify whether there is an API generated through at least one of the plurality of

modules

1120, 1121, and 1122 among a plurality of first APIs. For example, when there is an API generated through a first module 1120 and a second module 1121 among the plurality of

modules

1120, 1121, and 1122, the processor 230 may generate the fourth API 1130 by combining a third module 1122 with the API generated through the first module 1120 and the second module 1121.

According to an embodiment, the processor 230 may update an API list to include the generated fourth API and store the updated API list in the memory 210. When a request for using a plurality of second APIs is received from the first external electronic device 110 and a request for generating a new API is further received, the processor 230 may generate a third API by combining the plurality of second APIs and the newly generated fourth API. Further, upon receiving a request for using the third API, the processor 230 may update the API list to include the third API and the fourth API and store the updated API list in the memory 210.
