Billwerk+ Checkout
Billwerk + Checkout is a multi-purpose tool solving the following :
Payment window for one-off payments (charge session)
Payment window for storing customer payment method for recurring use or one-off MIT payments (recurring session)
Signup window for setting or changing payment method on a subscription (subscription session)
Billwerk+ Payments Checkout works by an initial server-to-server API call to create a checkout session.
The API call returns a session id that can be used with the Billwerk+ Checkout JS Web SDK to open the payment window.
A URL is also returned that can be used directly to show the payment window in a standalone browser window. Two different session types can be created as shown above.
