Correct answer & explanation
✓
POST /v1/messages with roomId and text in the JSON body
To send a message to a Webex Teams room, the developer must use POST /v1/messages with the roomId and text in the JSON body. The access token is provided in the Authorization header. Other methods like GET are for listing messages, and PUT is for updating existing messages. The endpoint must be exactly as documented.
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/messages with roomId and text in the JSON body
Why this is correct
The Webex Teams API uses POST /v1/messages to create a message. The request must include the roomId and text parameters in the JSON body. The access token is passed in the Authorization header as a Bearer token. This is the correct method and endpoint for sending a message to a room.
- ✗
GET /v1/messages with roomId as a query parameter
Why it's wrong here
GET /v1/messages is used to list messages, not to send them. It requires a roomId as a query parameter to filter messages for that room, but it does not create a new message. The developer needs to send a message, so POST is required. Using GET would only retrieve existing messages.
- ✗
PUT /v1/messages with roomId and text in the JSON body
Why it's wrong here
PUT is used to update an existing message, not to create a new one. To update a message, the message ID is required in the path, such as PUT /v1/messages/{messageId}. Without a message ID, PUT to the collection is invalid. The developer needs to create a message, so POST is the correct method.
- ✗
POST /v1/rooms/{roomId}/messages with text in the JSON body
Why it's wrong here
This endpoint does not exist in the Webex Teams API. Messages are created via POST /v1/messages, with the roomId included in the body. There is no sub-resource for messages under a room. Using an incorrect endpoint results in a 404 Not Found. The developer must use the documented endpoint.
