In order to start listening to messages, you will need to configure your endpoints. An endpoint is a URL that you control (e.g. a Zapier webhook URL).In the Settings go to the API & Webhooks section and click on “Configure” to get to the webhook portal.Click on “Add Endpoint” to add a new webhook address. Insert the URL you want to use and click on “Add”.You can now enable the events you want to receive (e.g. “call_ended”) and make a test call.
