Payment flow​

The Direct Model requires you to manage each payment step in your own application workflow. The steps vary by payment method:

  • Alipay / WeChat Pay: choose from three terminal modes (SDK, WAP, PCWEB) to match your deployment target — see WeChat Pay/Alipay.
Error handling

Handle failure results at every stage of the payment process. If a network error occurs, query the order result rather than assuming the payment succeeded. See Result Notification for details.
