Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
People API
Why it's wrong here
The People API manages user identities and profiles, exposing no subscription mechanism for room activity, so it cannot deliver message events. It is tempting because administrators often begin integration work by resolving people and memberships, and it would be the right resource for looking up a user's details or listing room members.
- ✗
Messages API
Why it's wrong here
The Messages API creates, lists and deletes messages; it returns data only when polled, so it cannot push real-time notifications. It is tempting because it is the resource that actually handles room messages, and it would be correct for sending a message or retrieving a room's message history.
- ✓
Webhooks API
Why this is correct
The Webhooks API satisfies the real-time notification constraint by having Webex push an HTTP POST to your listener the moment a message is created in the room, eliminating polling. Subscriptions target specific resources and events, so a messages/created subscription on that room delivers immediate delivery.
- ✗
Rooms API
Why it's wrong here
The Rooms API manages room metadata such as titles and membership, not event delivery. It tempts because rooms are where messages appear, but real-time notifications require registering a webhook via the Webhooks API, which pushes message-created events to a target URL.
