The Gravity Flow Stripe Extension allows workflows to authorize payments during the initial form submission (pre-orders), capture or cancel the payment at a later date, refund payments and create and cancel recurring subscriptions.
For example, the form can take the credit card details and authorize a payment during the initial form submission. Then the form can have a series of User Input and Approval steps to complete a process. Then at the end of the process the payment is captured.
The extension includes 4 step types:
Note that Stripe will automatically cancel (expire) an authorisation after 7 days so the workflow will need to capture the payment within one week.
