JetFormBuilder form submission hook for WordPress

jetformbuilder-submit-hook.php

<?php

/**
 * JetFormBuilder has no documentation about what hooks they fire or when they fire them.
 *
 * I ended up digging into their source code to try and find an action that fires for all
 * form submission, even if they don't have a custom "post submit action" set up.
 *
 * Using jet-form-builder/form-handler/after-send gets the job done.
