The WeChat Pay User Experience (UX) is different when customers are using a mobile or a desktop device. Here are the steps for each checkout flow.
WeChat Pay User Experience on Desktop
1. The customers select WeChat Pay from the payment options and the payment form appears.
2. The customers must fill out the WeChat Pay payment form.
3. After clicking "Submit Payment", a unique QR code is generated for the customers to scan. Since customers are using a desktop device, they need to scan the QR code with their WeChat mobile app.
4. Scan the QR code with a mobile device.
5. Authorize the payment.
After completing payment through the WeChat mobile app, customers are then redirected to your designated "Thank You page" in their mobile browser. The QR code generated by the form on the desktop device is no longer valid.
