Vapi

Webhook URL format: 
POST https://api.voxfra.com/webhook/vapi/{slug}
In your Vapi dashboard, set the Server URL for your assistant to the webhook URL above. Vapi sends an end-of-call report when the call ends. Minimum required fields: 
{
  "call": {
    "id": "call_abc123",
    "status": "completed",
    "startedAt": "2026-04-14T10:00:00Z",
    "endedAt": "2026-04-14T10:05:30Z"
  },
  "transcript": "Hello, how can I help you today?...",
  "customer": {
    "number": "+15551234567"
  },
  "recordingUrl": "https://recordings.vapi.ai/call_abc123.mp3"
}
Voxfra also reads analysis.summary, analysis.sentiment, and analysis.intent if present. For the complete reference, see Vapi.
