This blog is continuation of my previous blog where I had explained about setting up Communication Management in SAP S/4HANA Cloud:

In this episode I would like to explain the step by step procedure of using SAP API Business Hub so that we can use this to trigger/test our APIs from our SAP S/4HANA Cloud tenant.

1.  Launch SAP API Business Hub from and click ‘APIs’:

2.  Click on ‘Register’ button on top right corner:

3.  Fill up the registration form and click ‘Register’ to get your user created: 

You will receive a link for activation on the email id provided by you.

Note: This would be the user which can be used to access other SAP platforms like and SAP Community Network. Hence you can skip Step-2 and Step-3  if you already have a user.

4.  Login with your Username and Password:

5. Search for SAP S/4HANA Cloud and click to open the package:

6. Click on ‘Artifacts’ tab and search for your API (eg: Process Purchase Order), Click to open it:

7.  Go to ‘Resource’ Tab and click ‘Configure’. This will set the target SAP S/4HANA Cloud tenant where this API would be triggered (API Endpoint setting):

8. Provide details for configuration and click ‘Ok’:

Endpoint Alias: give any name

host: Host name of your SAP S/4HANA Cloud tenant (eg:

port: Port name of your SAP S/4HANA Cloud tenant (check with your Administrator)

Username: Username of your Communication User (refer previous blog)

Password: Password of your Communication User

9.  Your API Endpoint is now configured and ready to be used. Select the configured API Endpoint  from drop down:


These steps have now enabled us to trigger this API in our own SAP S/4HANA Cloud tenant, based on the method we need (like GET, POST etc.).

In my next blog, I would be explaining the steps to use ‘GET’ method of this API for fetching data from SAP S/4HANA Cloud.

Stay Tuned!
