Question

A developer is building an integration that must automatically post a summary to a Webex space whenever a new message containing a specific keyword is added to that space. To avoid continuously polling the Webex REST API, the developer decides to use a webhook. Which combination of webhook configuration and processing behavior correctly describes how this integration should work?

Accepted Answer

Register a webhook with resource 'messages' and event 'created'; Webex sends an HTTP POST to the target URL containing the message ID, and the app then issues a GET to retrieve the message content.

Answer

Register a webhook with resource 'messages' and event 'created'; Webex includes the full decrypted message text in the webhook payload, so no additional API call is required.

Answer

Register a webhook with resource 'rooms' and event 'updated'; Webex pushes the message body directly and the app filters locally.

Answer

Configure the integration to open a persistent WebSocket to the Webex API and subscribe to the 'messages' stream, since webhooks cannot notify on message creation.
