Provide a target URL where the webhook sends the notification
To receive real-time notifications, a webhook must be registered for the 'message.created' event. The webhook will POST to a specified URL when a message is created.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Poll the GET /v1/messages endpoint every second
Why it's wrong here
Polling is inefficient and not real-time; webhooks are preferred.
- ✓
Provide a target URL where the webhook sends the notification
Why this is correct
The webhook needs a URL to send the POST request to.
- ✗
Use the 'roomId' parameter to filter messages
Why it's wrong here
Filtering is possible but not required for all rooms; the webhook can be set to all rooms.
- ✓
Register a webhook for the 'message.created' event
Why this is correct
This triggers the webhook when a message is created.
- ✗
Send a POST request to /v1/webhooks with 'resource: messages' and 'event: seen'
Why it's wrong here
'seen' is not a valid event; the correct event is 'created'.
