# Guide: Webhook Form Integration (2 min)

Custom Webhooks allows you to enter an URL (endpoint) of any of your services to get data from forms of your Unicorn Platform site.

You can enter an URL and specify the parameters of the GET or POST request to your endpoint.

Also, if a data of your users does not match what your service expects or it does not work for some reason, you can specify an error message and pass it to the response object. It will be displayed under the form input instead of our default message "Uh. We could not connect to the server. Please try again later".

`{ "error": "You filled in the field incorrectly. Try again." }`
