200-901 Cisco Platforms and Development Practice Question
A network administrator wants to use Cisco Webex APIs to automate sending messages to a specific room. Which THREE pieces of information are required to send a message using POST /v1/messages?
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
✓
Message body as plain text or markdown
The POST /v1/messages endpoint requires authentication via a bearer token in the Authorization header (option E). To specify the recipient, you must provide either a roomId or toPersonEmail (option C). The message body must be included as text or markdown (option B). Therefore, options B, C, and E are required. Options A and D are incorrect because A uses a Meraki API key (not used in Webex) and D requires a user ID (not needed for sending messages to a room or person).
