Basic Fulcrum webhook endpoint written in PHP. Enter your form id & email, upload to a web server, and configure your webhook settings in Fulcrum to point to this endpoint. Default action emails webhook JSON payload, but realistically, you would want to do something with the recordArray and formArray variables.
