## How WeChat Pay works

WeChat Pay securely simplifies mobile payments. The payment process for WeChat Pay follows these steps:

1. Your consumer selects WeChat Pay as their preferred payment method from your payment page.

2. You initiate a POST request to the /payments endpoint to submit the payment to WeChat Pay. Ensure the paymentMethodType attribute is set to wechatpay.

3. J.P. Morgan returns a redirect URL to display a QR code to your consumer.

4. Your consumer scans the QR code using the WeChat mobile app.

5. Your consumer confirms the transaction by entering the payment password.

6. J.P. Morgan returns confirmation of the payment result.

> You are notified of the payment result through webhook notifications. To learn more, check out the [Notifications API](/docs/commerce/optimization-protection/capabilities/notifications/index).
