Voice Agent Builder
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.
You can have multiple Webhook Nodes for a single Voice Agent, if you want to sync the result of the call at multiple places.
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.*}}, and {{gathered_context.*}}, including the final call outcome {{gathered_context.call_disposition}}.
For the full list of available variables, authentication options, and receiver examples, see the Webhook Payloads developer reference.
An example of the payload is given below
{
"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}}"
}
