The payment process differs in test and live modes. This is because AfterPay does not have test accounts and in test mode Stripe simulates a response from AfterPay.
In Test mode, the payment process is as follows:
At checkout, the customer chooses to pay in installments using a buy now pay later method. The customer is redirected to the buy now pay later payment confirmation page you will be presented with a choice between a successful or unsuccessful payment. This is necessary so that you can test both options.
In Live mode, the payment process is as follows:
At checkout, the customer chooses to pay in installments using a buy now pay later method. The customer is redirected to the buy now pay later method’s site or app to create an account or log in. They can accept or decline the terms of the repayment plan and return to your checkout flow.
