Multisite Privacy & Formidable Forms Zapier

We are having issues getting Zapier to recognize forms on our multisite install due to the Multisite Privacy Plugin. We reached out to Formidable and got this response, hoping you can help:

"Maybe you can contact them and ask if there is a way to exclude some urls from the login requirement? Or perhaps we need to make a change to trigger our API key to set the logged in user sooner? Right now, we setup the logged in user on the 'wp_loaded' hook.

Is it possible to contact them and ask when custom login would need to be done in order for their plugin to recognize it?"
