To send the phone number of the caller when the call comes in to an external backend, you would typically use a webhook that is triggered upon receiving an inbound call. The webhook would be configured to send the relevant data, such as the caller's phone number, to your specified backend endpoint.
Here's a general outline of the steps you would take:
1. Set up a webhook endpoint on your server that is capable of handling HTTP POST requests.
2. Configure the webhook URL in your VAPI settings to point to the endpoint you created.
3. When an inbound call is received, VAPI will trigger the webhook and send the call data, including the caller's phone number, to your endpoint.
4. Your server processes the incoming data and can take further actions as needed.
If you need assistance with setting up the webhook or have specific requirements for the data you want to send, please provide more details, and I'll be happy to guide you through the process.
