C_CPI Integration Suite Development Practice Question
An integration developer needs to expose an integration flow in SAP Cloud Integration so that an external partner can call it over HTTPS using a URL. Which adapter should be added as the sender to the integration flow?
⚠ Common exam trap
The trap here is assuming any sender adapter that supports HTTP transport can serve as a generic HTTPS endpoint, when SOAP and OData enforce their own message contracts.
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
Exposing an integration flow to an external caller over HTTPS requires the HTTPS sender adapter, which creates an endpoint URL and handles inbound HTTP requests with configurable authentication. SOAP, OData, and IDoc sender adapters impose protocol-specific message formats and are not suited to a generic HTTPS invocation from a partner.
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 designed to receive IDoc messages, typically from SAP systems, and does not expose a general HTTPS endpoint for external partners. It is used for SAP-to-SAP integration over the IDoc protocol, so it cannot satisfy a requirement to accept HTTPS calls from a third party.
- ✗
SOAP sender adapter
Why it's wrong here
The SOAP sender adapter also exposes an endpoint, but it expects SOAP envelopes and WSDL-based contracts rather than a plain HTTPS URL call. If the partner is calling a REST-style URL, a SOAP sender would reject the request format, so it does not match the stated requirement.
- ✓
HTTPS sender adapter
Why this is correct
The HTTPS sender adapter makes an integration flow reachable at an endpoint URL and accepts inbound HTTP requests from external callers. It is the standard way to expose a flow as an API for a partner, and it supports authentication methods such as client certificate or OAuth, which fits the scenario.
- ✗
OData V2 sender adapter
Why it's wrong here
The OData V2 sender adapter exposes an OData service endpoint with entity sets and query semantics, not a generic HTTPS URL. A partner calling a simple URL with a JSON or XML body would not conform to OData conventions, so this adapter is inappropriate for the scenario.
