Memberstack prevents sign up forms, profile forms, and login forms from submitting to Webflow. This is primarily to avoid unknowingly exposing a customer's password & profile information.

The best workaround right now is to use Webhooks or our Zapier Integration to send sign up data & profile update data off to other 3rd party services. Note: We do not ever expose the member's password. This includes Zapier & Webhooks.
