Question

A developer is building an integration that must react immediately whenever a new message is posted in a specific Webex space, without repeatedly querying the Webex REST API. The solution should minimize API calls and latency. Which approach best meets these requirements?

Accepted Answer

Create a webhook that subscribes to the messages resource with a filter for the target roomId, so Webex sends an HTTP POST to the integration's callback URL when the event occurs

Answer

Configure a scheduled job that calls GET /messages every 5 seconds and compares results against a locally cached message list

Answer

Establish a persistent SIP subscription to the space using SIP SUBSCRIBE/NOTIFY dialogs to receive message events

Answer

Enable the Directory Connector to forward space activity events to the integration via LDAP referrals
