Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
POST /v1/rooms
Why it's wrong here
POST /v1/rooms creates a new room, not a message within an existing one. It is tempting because POST is the correct verb for creation, but the resource collection is wrong: messages are posted to /v1/messages with the roomId in the body.
- ✗
PUT /v1/messages
Why it's wrong here
PUT /v1/messages is not a valid Webex endpoint; messages are created with POST /v1/messages. It is tempting because PUT also writes data, but Webex does not expose message creation via PUT, and PUT semantics imply replacing an existing resource at a known URI.
- ✗
GET /v1/messages
Why it's wrong here
GET /v1/messages retrieves message details and cannot create one; sending requires POST to /v1/messages. It is tempting because the endpoint path matches the resource, but the HTTP verb governs the operation, and GET is idempotent retrieval rather than creation.
- ✓
POST /v1/messages
Why this is correct
Sending a message creates a new resource in the Webex messaging collection, so the POST method targets /v1/messages with the roomId and text in the JSON body. GET retrieves existing messages, and PUT or DELETE would modify or remove them, not send.
