When using Stripe Checkout, there isn’t a way to trigger a webhook or zapier automation based purely on a successful payment, and it would be highly beneficial for all forms that terminate in a Stripe Checkout (which I imagine are many).
I can redirect to another form based on successful payment, but then I can only trigger a zapier workflow enrollment or a webhook based on Data Received or Form completion, not a Step Load, and both of those conditions require a user action of some kind.
