As an Administrator, you can check the complete list of standard integration interfaces exposed by SAP Cloud for Customer. This could be done via the
“Application and User Management” Workcenter, “Service Explorer” view. Most of the Business Objects of the application are being exposed through interfaces
(to read, create or update them).
From the “Service Explorer” you can check the documentation of the interfaces where samples for its usage are included. You can also download the Service
definition (WSDL) from there from its consumption from any application.
Before being able to use it, you need to create a Communication Arrangement (under the “Application and User Management” Workcenter). In this Communication Arrangement you’ll need to specify the system associated to it (you could create one specific system for this or to reuse an existing one). But the most relevant data to configure in the Communication Arrangement is the authorization type to use (username and password or Client Certificates, and
the credentials to be used). These credentials must be set in the Application consuming the Web Service.
Based on this, once the Communication Arrangement is ready, you can download the WSDL of the Service (from “Service Explorer”) and to import it in the application to consume the service (a Web Service Client in this case). You’ll need to configure the authentication credentials and the data you want to use in the Web Service interface before invoking it.
