Response

Successful request response

  • an HTTP code 201
  • an id which is unique to the payment - we recommend storing the "id" as this can be used to manage the payment later
  • in redirect field there will be a qrcode in base 64 to display to your customer to complete the payment
  • a link to query the payment status
  • an object which will give flow information such as method (e.g. wechatpay) and type (direct)

Testing

All requests return the same encoded QR code, allowing you to test the synchronous response and the embedding of the QR code image within your checkout page.

Following a short delay test payments will automatically update to authorize once you receive the successful payment response.
