Webhooks

The Webhook node fires an HTTP POST to a URL when the conversation ends. Use it to send transcripts, trigger CRM updates, create support tickets, or notify external systems. The Webhook node is a post-processing node — it runs after the conversation ends and receives the full conversation data. You can chain it after Structured Output to also send extracted fields.

Adding a Webhook node

  1. Drag the Webhook node from the sidebar (Post-Processing category) onto the canvas
  2. Connect the End node’s output to the Webhook node’s in handle
  3. Set the transferTarget URL

Parameters

Payload

Voiceblox checks the HTTP response status. The call proceeds regardless of the webhook response — failures are logged but don’t crash the session.
