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 send messages to it over HTTPS using a custom URL path. The partner will authenticate with a client certificate. Which sender adapter should the developer configure?
⚠ Common exam trap
The trap here is assuming any adapter that uses HTTPS as transport can serve as a generic HTTPS endpoint, when SOAP and OData sender adapters require protocol-specific message formats.
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 as an HTTPS endpoint for an external partner requires the HTTPS sender adapter. It allows a custom URL path and supports client certificate authentication via the tenant's keystore. Other sender adapters such as SOAP, OData, and IDoc expect specific protocol payloads and do not provide a generic HTTPS endpoint, so they cannot fulfill the partner integration requirement described.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
OData V2 sender adapter
Why it's wrong here
The OData V2 sender adapter exposes an OData service endpoint with entity sets and query options. It is designed for OData consumers, not for arbitrary HTTPS message senders. Configuring it would require the partner to speak OData, which is not stated in the scenario, so it does not meet the requirement of a custom HTTPS endpoint with client certificate authentication.
- ✗
SOAP sender adapter
Why it's wrong here
The SOAP sender adapter exposes a SOAP web service endpoint, not a generic HTTPS endpoint. While SOAP runs over HTTPS, the adapter expects SOAP envelopes and WSDL-based operations. A partner sending plain HTTPS messages would not be able to invoke it correctly, and the requirement does not mention SOAP, so this adapter is inappropriate.
- ✗
IDoc sender adapter
Why it's wrong here
The IDoc sender adapter receives IDoc messages from SAP systems, typically over tRFC or qRFC. It does not expose an HTTPS endpoint and cannot accept client certificate authentication from an external partner. This adapter is used for SAP-to-SAP IDoc communication, not for partner HTTPS messaging, so it is incorrect here.
- ✓
HTTPS sender adapter
Why this is correct
The HTTPS sender adapter in SAP Cloud Integration exposes an integration flow as an HTTPS endpoint that external systems can call. It supports client certificate authentication through the configured keystore, and the URL path can be customized. This directly matches the requirement to accept partner messages over HTTPS with client certificate authentication.
