C_CPI Integration Suite Development Practice Question
An integration developer needs to expose a SOAP-based web service from SAP Cloud Integration. The service must accept a synchronous request, transform the payload using a message mapping, and return a response. Which adapter type should be used on the sender side to receive the SOAP request?
⚠ Common exam trap
The trap here is assuming that any HTTP-based adapter can handle SOAP, but only the SOAP sender adapter provides built-in SOAP protocol support and security.

Correct answer & explanation
✓
SOAP sender adapter
To expose a SOAP web service from SAP Cloud Integration, the SOAP sender adapter is the appropriate choice. It natively handles SOAP envelopes, supports synchronous request-response, and provides WS-Security options. Other adapters like HTTPS or OData do not understand SOAP and would require custom parsing.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
IDoc sender adapter
Why it's wrong here
The IDoc sender adapter is used to receive IDoc messages from SAP systems, typically via tRFC or qRFC. It is not designed to accept SOAP requests from external clients. Using it would not allow the integration flow to be called as a SOAP web service, and it would not support the required synchronous response pattern.
- ✗
HTTPS sender adapter
Why it's wrong here
The HTTPS sender adapter can receive HTTP requests but does not natively understand SOAP envelopes or WS-Security headers. While you could parse SOAP manually, it would require additional steps and would not provide the built-in SOAP fault handling and security features. For a SOAP web service, the SOAP sender adapter is the correct choice.
- ✗
OData sender adapter
Why it's wrong here
The OData sender adapter exposes an OData service, not a SOAP service. It expects OData protocol requests and returns OData responses. While it can handle HTTP, it does not process SOAP envelopes or support WS-Security. Therefore, it cannot fulfill the requirement to expose a SOAP-based web service.
- ✓
SOAP sender adapter
Why this is correct
The SOAP sender adapter in SAP Cloud Integration is specifically designed to receive SOAP requests over HTTP or HTTPS. It supports WS-Security and can handle synchronous request-response patterns. Using it allows the integration flow to be exposed as a SOAP web service, which is exactly what the scenario requires for accepting and responding to SOAP calls.
