Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
GET /v1/messages
Why it's wrong here
GET retrieves message history from a room; it cannot create one, so no message is sent. It is tempting because GET /v1/messages is the correct endpoint for listing or reading existing messages, which is the right choice when a developer needs to fetch room content rather than post it.
- ✗
PUT /v1/messages
Why it's wrong here
PUT replaces an existing resource at a known URI; Webex message creation uses POST to /v1/messages, so PUT sends nothing. It is tempting because PUT /v1/messages targets the same collection, and would suit updating a message if the API supported full replacement semantics there.
- ✗
DELETE /v1/messages
Why it's wrong here
DELETE removes an existing message by ID; it cannot create one, so nothing is sent to the room. It is tempting because DELETE /v1/messages operates on the same messages resource, and would be correct when a developer needs to retract or remove a previously posted message.
- ✓
POST /v1/messages
Why this is correct
Creating a message is a resource-creating operation, so the Webex messaging API expects POST against the /v1/messages collection endpoint, with the roomId and text in the JSON body. GET on that path would only list messages.
