Wix Forms Request: Triggering Form Submission Automations When a Payment is Made
Collecting votes
Currently in Wix Forms, submission automations can only be triggered when a payment form is submitted, not when a payment is made.
However, you can create an automation that triggers when an order is marked as paid using the 'Checkout & Orders' trigger.

We are always working to update and improve our products, and your feedback is greatly appreciated.
