Webhooks

Twilio Proxy can call a webhook in your system to notify you of various events. To enable webhooks, configure an optional callback URL on your Proxy Service either using the REST API or the Console.

name description
CallbackUrl These webhooks are fired for each new interaction and are informational only.
OutOfSessionCallbackUrl A URL to send webhooks to when an action (inbound call or SMS) occurs where there is no session or a closed session. If your server (or a Twilio function) responds with valid TwiML, this will be processed. This means it is possible to e.g. play a message for a call, send an automated text message response, or redirect a call to another number.
InterceptCallbackUrl Fires on each interaction. If responded to with a 403 to this webhook we will abort/block the interaction. Any other status or timeout the interaction continues.

Example Webhook Payloads

All webhook parameters will be submitted as form parameters (application/x-www-form-urlencoded). Each webhook above will pass you specific parameters as shown below with their example values.
