A webhook sends call data to your system through a POST request. A call can finish successfully even if delivery to your endpoint fails.

​
Configure and test

  1. Open the voice agent and go to Advanced → Post-call.
  2. Set the outgoing webhook URL. The inbound webhook supplies agent context and serves a different purpose.
  3. Save and publish the agent configuration.
  4. Make a controlled call through Test agent and wait for analysis.
  5. Inspect the received body and HTTP response in your receiver and in Calls → Webhooks.
The current editor has no sample-payload test button. Test calls can trigger real actions in your receiver.

​
Investigate delivery

Open an event in Calls → Webhooks to inspect its URL, status, attempts, HTTP response, raw data, and associated call. Store the event ID alongside the call ID in your logs. Make your receiver tolerate repeated deliveries: a retry must not create duplicate tickets or repeat an operation. These deliveries are separate from messaging channel webhooks, inbox automations, and lead-routing events. Each has its own configuration and content.
