This article mainly introduces "how to consume API's ABAP in SAP's ABAP programming environment". In daily operation, I believe many people have doubts about how to consume API's ABAP in SAP's ABAP programming environment. Xiaobian consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the doubts of "how to consume API's ABAP in SAP's ABAP programming environment". Next, please follow the editor to study!

Log in to api.sap.com and find the corresponding API directory according to the keyword SuccessFactors:

Find the foundation/Platform-level API, and after entering

Select User Management:

Click Logon to use the control features that come with the API console:

Click Try Out, and you can use the test function that comes with the API console just like you did with postman:

The filter operation of this OData API can be tested in $filter string:

From the test results, it can be found that firstName is the user of Sami, and the user ID in this sandbox system is 50004:

Click Show API Key to get an API key so that you can call API outside the API console.

Click Code Snipet, you can copy the automatically generated API calling code and paste it directly into the application.

Click Curl to get the command line for testing using the tool curl:

> curl-request GET-url "https://cessfactors/odata/v2/Userhttps://cessfactors/odata/v2/Userhttps://odata/v2https:///odata/v2https://ata/v2https:///odata/v2https:///odata/v2https://data/v2https://odata/v2https:///odata/v2https:///odata/v2https://data/v2https:///odata/v2https://odata/v2https:///odata/v2https:///odata/v2https://data/v2https://

Consume the API code in the SAP UI5 application:
