title: In the Ninja Forms Webhooks extension, is it possible to intercept the submit without editing the plugin's process() function?
body: <p>I am attempting to edit a form's submission variables before they are submitted to the action URL. I am able to accomplish what I want by changing </p>
  
  <pre><code>$args[ $vars['key'] ] = $value;
  </code></pre>
  
  <p>in the initial foreach loop of the process() function in action-webhooks.php to </p>
  
  <pre><code>if (is_array ($value)) {
      $args[ $vars['key'] ] = implode(';', $value);
  }
  else {
      $args[ $vars['key'] ] = $value;
  }
  </code></pre>
  
  <p>This is obviously a bad solution since this code will be overwritten if the plugin is updated. Is there an action or filter that I can use to accomplish this from my own code? Thanks.</p>
