Create a POST request

Before testing your trigger, you will need to send test data to your webhook via a POST request. The steps listed below explain how to make the POST request via Postman, but you’re welcome to use any program you’d like.

  1. Copy the webhook URL generated by Zapier.
  2. In Postman, click New to start a new request.
  3. Select HTTP Request from the Create New menu.

  2. Select POST from the dropdown to the left of the webhook URL.

  1. Select the Body tab, choose the form-data radio button, and then enter the keys and appropriate test data from the following table. Make sure to format phone numbers correctly. You'll need to use a real phone number when testing your webhook in order for the profile to be added to your list.
