To capture the `from_number` field from Retell in n8n, you'll need to set up a webhook that receives call data from Retell.

When Retell sends call data (via webhook or API response) , the `from_number` field is included in the call object. [(1) ](<https://docs.retellai.com/api-references/register-phone-call>)

The call response structure includes:
```json
{
  "call_type": "phone_call",
  "from_number": "+12137771234",
  "to_number": "+12137771235",
  "direction": "inbound",
  "call_id": "Jabr9TXYYJHfvl6Syypi88rdAHYHmcq6"
}
```


**In n8n:**
1. Use a **Webhook node** to receive data from Retell
2. Configure your Retell agent to send webhooks to your n8n production URL
3. Access the `from_number` field in subsequent nodes using the expression: `{{ $json.from_number }}`

**Important:** Make sure your n8n workflow is set to **production mode** and you're using the production webhook URL in Retell. Also ensure the webhook is using the **POST method**. [(2) ](<https://discord.com/channels/1186424376300679209/1434902217621639218>)

If you're not receiving any data, verify that:
- The workflow is published/active in n8n
- You're using the production URL (not test URL)
- The agent is published after adding the webhook
