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 using a simple HTTPS POST with a JSON payload. Which sender adapter should be configured?
⚠ Common exam trap
The trap here is equating any HTTP-based protocol adapter with plain HTTP, when SOAP and OData adapters enforce their own message structures and will not accept arbitrary JSON.
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
✓
The HTTPS sender adapter, because it accepts inbound HTTP and HTTPS requests and can process JSON payloads.
The HTTPS sender adapter is designed to expose an integration flow as an HTTP or HTTPS endpoint that accepts inbound requests. It handles POST requests and can carry JSON payloads directly into the flow, matching the partner's simple HTTPS POST requirement. SOAP, IDoc, and OData sender adapters each impose their own protocol formats and would require the partner to conform to those formats rather than sending plain JSON.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The SOAP sender adapter, because it supports JSON payloads natively and can be invoked over HTTPS.
Why it's wrong here
The SOAP sender adapter expects SOAP envelopes and is designed for SOAP-based web service calls. Although it runs over HTTPS, it does not natively accept plain JSON payloads as a request body for a simple POST. Using it would require the partner to wrap the JSON in a SOAP envelope, which contradicts the requirement for a simple HTTPS POST with JSON.
- ✗
The IDoc sender adapter, because IDoc is the standard SAP format for partner communication and can carry JSON.
Why it's wrong here
The IDoc sender adapter is used to receive IDoc messages, typically from SAP systems using the ALE framework. It does not accept arbitrary JSON payloads over HTTPS from external partners. Configuring it would require the partner to send IDoc-formatted data, which is not the simple HTTPS POST with JSON described in the scenario, so this option is incorrect.
- ✗
The OData sender adapter, because OData is built on HTTP and therefore accepts any JSON payload sent via POST.
Why it's wrong here
The OData sender adapter exposes an OData service endpoint and expects requests that follow the OData protocol, including specific URL conventions and metadata handling. It does not accept arbitrary JSON payloads at a plain HTTP endpoint. While OData uses HTTP, the request must conform to OData semantics, which conflicts with the requirement for a simple HTTPS POST with JSON.
- ✓
The HTTPS sender adapter, because it accepts inbound HTTP and HTTPS requests and can process JSON payloads.
Why this is correct
The HTTPS sender adapter is the correct choice for exposing an integration flow as an HTTP or HTTPS endpoint. It accepts inbound requests with various content types, including JSON, and passes the payload into the flow for processing. It supports standard HTTP methods such as POST, making it the natural fit for a partner sending a simple HTTPS POST with a JSON body.
