# Webhook

> Webhook node allow you to sync the result of Voice Agent runs to your external systems, like CRM or to other workflow orchestrator like Zapier or n8n.

## Video Tutorial

<Note>
You can have multiple Webhook Nodes for a single Voice Agent, if you want to sync the result of the call at multiple places.
</Note>

During [agent onboarding](/getting-started/first-agent), the Launch step can add one webhook for you. Paste a Slack, n8n, Zapier, or backend URL and Menace Voice attaches a Webhook node with a recap payload. You can still edit the payload in the editor.

### Creating the Webhook Payload
The payload can contain a valid JSON, and you can reference context variables while constructing it using double-brace syntax — for example `{{workflow_run_id}}`, [`{{initial_context.*}}`](/core-concepts/context-and-variables#initial_context), and [`{{gathered_context.*}}`](/core-concepts/context-and-variables#gathered_context), including the [final call outcome](../developer/call-dispositions) `{{gathered_context.call_disposition}}`.

For the full list of available variables, authentication options, and receiver examples, see the [Webhook Payloads developer reference](/developer/webhooks).

An example of the payload is given below

```json
{
  "call_id": "{{workflow_run_id}}",
  "first_name": "{{initial_context.first_name}}",
  "rsvp": "{{gathered_context.rsvp}}",
  "disposition": "{{gathered_context.call_disposition}}",
  "duration": "{{cost_info.call_duration_seconds}}",
  "recording_url": "{{recording_url}}",
  "transcript_url": "{{transcript_url}}"
}
```
