You can create a workflow rule in your AppSheet app that will post a JSON payload to a PHP service that you write.

To do this:

  1. Create a webhook workflow rule.

  2. Add a JSON payload template to the workflow rule. The template controls the format of the JSON data sent in the body of the webhook post.

  3. Your PHP code that is invoked by the webhook post can retrieve the post body data by specifying:
    $postdata = json_decode(file_get_contents("php://input"));

  4. After successfully processing the webhook request, your PHP code should return a JSON object containing  {"Status":"Success"}.
