200-901 Practice Question: A developer wants to use Cisco Webex Teams API to…
A developer wants to use Cisco Webex Teams API to send a message to a specific room. Which of the following request JSON body fields is required?
⚠ Common exam trap
Cisco often tests the distinction between room messages and direct messages, and the trap here is that candidates may assume 'text' is required because it is the most obvious content field, but the API allows messages without text (e.g., only a file), making 'roomId' the only truly required field for room-targeted messages.

Correct answer & explanation
✓
"roomId"
The Cisco Webex Teams API requires the 'roomId' field in the request body to identify the specific room where the message will be sent. Without this field, the API cannot determine the destination, and the request will fail with a 400 Bad Request error. The 'roomId' is a mandatory parameter for sending messages to a room, as documented in the Webex API reference.
