You will learn
In this tutorial, you will learn how to use the pre-generated code from the SAP API Business Hub in an ABAP report. You will need to have configured your ABAP system to make an HTTP request.
Prerequisites
- ABAP system should be configured to call http APIs
- Testing API Business Hub APIs with Curl
Configuring the proxy settings is not a required step for all systems. Verify that your system needs to have the proxy configured before completing steps 1 through 3.
Step 1: Configure your ABAP Proxy
From the SAP Logon pad, launch the SAP Logon screen.
Enter the login credentials in R/3 ABAP System.
Configure your proxy settings by going to transaction SICF and clicking on Execute.
Open Proxy settings page by pressing Ctrl + F2 and set the proxy.
Step 2: Get your SSL Certificate
In Google Chrome, export SSL certification.
To get to the SSL certificate, enter F12, go to Security tab, click on View Certificate, click on Details, and select Copy to File. From here, you can export the certificate by path.
Step 3: Add your certificate to ABAP
Once you export the certificate by path, you will need to import it into your ABAP system. To import the certificate in your ABAP system, go to the transaction STRUST, open SSL client SSL Client (Standard), and switch to Edit mode.
Click on Import Certificate. Select the certificate you exported from Google Chrome in the previous step. Click Add to Certificate List and save.
In order to reflect your new SSL settings, you will need to restart your ICM. To restart the ICM, go to the transaction SMICM. Navigate to Administration > ICM > Exit Hard > Global.
The ICM restart message will appear. Select Yes.
Restart the ICM processes. Make sure no client is communicating during restart.
Step 4: Create the ABAP program report
In your ABAP system, go to the transaction se38.
Create a new report. Enter the program name, such as ZAPI_HUB_TEST, select Source Code, and click Create.
Provide the following details on the Program Attributes screen.
| Field Name | Value |
|---|---|
| Title | testing API |
| Type | Executable program |
| OPTIONAL: Status | Test Program |
Save, Activate, and Execute the report.
Step 5: Get the ABAP code from API Business Hub
To get the ABAP code snippets that are available in the SAP API Business Hub, go to the SAP API Business Hub, which can be found at api.sap.com, from your browser. Navigate to the API packages page and find the SAP Translation Hub API.
Click the Expand Operations link on the Domains API. Click Generate Code on the GET /domains method.
Click on the tab for ABAP from available languages and click Copy to Clipboard.
Paste in the copied ABAP code from the API Hub in the text box below.

Step 6: Add API call and run from ABAP
Back in your ABAP system, paste the code snippet into the report.
Replace the <API_KEY> with your API key value. This is also available in the SAP API Business Hub and is specific to your user and app. Save, Activate, and Execute the report.
If you see a message returned with data, and not an error, you have successfully tested a call to an API from the SAP API Business Hub.
