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 synchronously over HTTPS with a JSON payload. Which sender adapter should be used for this requirement?
⚠ Common exam trap
The trap here is choosing a protocol-specific sender adapter by association with the partner's industry, when generic synchronous JSON over HTTPS is served by the HTTPS sender 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
Exposing an integration flow as a callable endpoint that accepts JSON and returns a synchronous response is exactly what the HTTPS sender adapter provides. It terminates the incoming HTTP request, applies the configured authentication, and passes the body into the flow. Protocol-specific adapters such as SOAP, IDoc, or SuccessFactors impose their own payload formats and cannot accept an arbitrary JSON call 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.
- ✗
SuccessFactors sender adapter
Why it's wrong here
The SuccessFactors sender adapter is a specialized adapter for inbound communication from SAP SuccessFactors, using its own protocol and payload conventions. It cannot serve as a generic HTTPS endpoint for an unrelated external partner and would not accept a plain JSON request body, making it unsuitable here.
- ✗
IDoc sender adapter
Why it's wrong here
The IDoc sender adapter is inbound-only and is used to receive IDoc documents from an SAP backend system through the Cloud Connector. It has no concept of an externally callable HTTP endpoint and cannot accept arbitrary JSON from a third-party partner, so it does not fit this scenario.
- ✓
HTTPS sender adapter
Why this is correct
The HTTPS sender adapter exposes an integration flow as an HTTP endpoint that external clients can call and receive a synchronous response from. It supports authentication options such as client certificates and OAuth, and it handles JSON or XML payloads directly, making it the correct choice for a partner-initiated synchronous JSON request.
- ✗
SOAP sender adapter
Why it's wrong here
The SOAP sender adapter also exposes an endpoint, but it expects SOAP envelopes with a defined WSDL contract. A partner sending a plain JSON body would not be able to invoke it without wrapping the payload in SOAP, which contradicts the stated requirement of a straightforward JSON call.
