Payments

Create a new customer-initiated payment

post

Creates a new customer-initiated payment.

After a payment is created a payment method (card, bank, saved token) must be added to it. The user can attempt adding payment method multiple times until ultimately one is successful. The checkout process is continued by either redirecting the user to the gateway hosted checkout page or integrating directly with EGW APIs.

Additionally, the setupToken fields can be used to save the used payment method for future payments.
