C_CPI Integration Suite Development Practice Question
You need to configure an integration flow in SAP Cloud Integration to receive messages from an external partner via HTTPS. The partner will send messages to a specific endpoint and expects a synchronous response. Which sender adapter should you use?
⚠ Common exam trap
It's easy for candidates to confuse HTTPS with SOAP or OData, assuming that any HTTP-based protocol requires a specialized adapter.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
HTTPS sender adapter
The HTTPS sender adapter is the correct choice for receiving messages from an external partner over HTTPS with a synchronous response. It supports standard HTTP methods and can be configured with authentication and endpoint settings. Other sender adapters are protocol-specific and do not match the plain HTTPS requirement.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
SOAP sender adapter
Why it's wrong here
The SOAP sender adapter is used for SOAP-based web services, which require a WSDL and SOAP envelope. While it can handle synchronous requests, the scenario specifies HTTPS, not SOAP. Using a SOAP adapter would impose additional protocol requirements and is not the appropriate choice when the partner is sending plain HTTPS requests. Therefore, it is incorrect.
- ✓
HTTPS sender adapter
Why this is correct
The HTTPS sender adapter in SAP Cloud Integration is designed to accept incoming HTTP/HTTPS requests from external systems. It supports synchronous request-response patterns, allowing the integration flow to process the request and return a response to the caller. This matches the requirement of receiving messages from a partner and providing a synchronous response, making it the correct adapter for this scenario.
- ✗
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 SOAP. It is not designed for generic HTTPS requests from external partners. This adapter is specific to SAP IDoc communication and would not work for the described scenario, where the partner sends messages over HTTPS expecting a synchronous response.
- ✗
OData sender adapter
Why it's wrong here
The OData sender adapter exposes an OData service and is used when the sender communicates via OData protocol. Although OData is based on HTTP, it requires specific URL conventions and metadata. The scenario does not mention OData; the partner sends plain HTTPS messages. Therefore, the OData adapter is not suitable and would introduce unnecessary complexity.
