There are several third-party tools that you can use to test and verify your webhook settings. An example that we like to use is https://webhook.site/. These sites create unique endpoints for you to use (temporarily) for testing.
You can set this endpoint as your webhook URL, then send a request to it while keeping the Request Bin or Webhook Site open in a browser window. It will display the received POST request, including the headers and data.
