Checkout Flow

1. Create invoice

2. Make decision on the next step

   When invoice was created, you can decide what to do next.

   Here are two cases possible, depending on the payment method, specified when creating invoice:

   • if paymentMethod.formType is cards - you need to create card token firstly.
   • if paymentMethod.formType is not cards - you can create checkout transaction.

3. Check invoice status and decide what to do next.

4. Receive IPN.
