3713139 - How to Troubleshoot SAP Ariba SOAP API Issues (Connectivity, Authentication, Payload, Timeout, General)

When I attempt to send or receive SOAP messages between my middleware (such as SAP CPI or SAP PI/PO) and SAP Ariba, the integration fails. I may see connection errors, SSL handshake failures, authentication errors, SOAP validation errors, or timeout-related issues. As a result, my SOAP web service calls are not processed successfully.

One or more of the following issues occur while integrating with SAP Ariba SOAP APIs:

• Unable to connect to SAP Ariba SOAP endpoint

• SSL handshake failures

• HTTP 401 Unauthorized or Invalid Security Token errors

• SOAP request rejected due to XML or schema validation errors

• Timeouts, slow responses, or no response received from Ariba

• HTTP 500 internal server errors

Applicable for the following environments:

• SAP Ariba SOAP APIs

• Integration via middleware such as SAP CPI, SAP PI/PO, or third-party ESB

• Cloud Integration Gateway (CIG)

• Inbound or outbound SOAP web service calls
