API docs for WPForms are located here https://wpforms.com/?p=8374&post_type=wpforms_doc&preview=1&_ppp=857193bee8

Requests can only be made to domains associated by this application.

These params will be URL-encoded and appended to the URL when making the request.

Authentication headers are included automatically

Zapier will apply these optional headers and values to the request in addition to any headers created as part of the authentication mechanism.

Zapier will pass this along raw. If you would like to provide complex JSON, try a "Code by Zapier" step to build the structure and pass it along here. For example, {"foo": "bar"} is perfectly valid.
