WeChat Pay Official account payments

Accept payments from your WeChat Official page.

A WeChat Official page is similar to a Facebook page or Verified Twitter profile. In addition to keeping your WeChat followers up-to-date, you can also serve your mobile website within the WeChat app, and initiate WeChat Pay payments.

When shoppers proceed to pay from your WeChat Official page, they are prompted to verify the payment. If successful, they are redirected back to your mobile website and presented with the payment result.

Official account payments must be initiated from the WeChat in-app browser. They cannot be initiated from another browser, such as Chrome or Safari.

Before you begin

These instructions explain how to add WeChat Pay to your existing API-only integration. The API-only integration works the same way for all payment methods. If you haven't done this integration yet, refer to our API-only integration guide.

Before starting your WeChat Pay Official account payments integration:

  1. Make sure that you have set up your back end implementation.
  2. Add WeChat Pay in your test Customer Area.
  3. Register for a WeChat Official (服务号) account:

WeChat will contact you to verify your information and provide an agreement you need to sign. Once approved, you can accept WeChat Pay payments initiated using the WeChat browser.

Build your payment form for WeChat Pay

Show WeChat Pay as an available payment method for shopper's accessing your mobile website the through the WeChat in-app browser.

We provide logos for WeChat Pay which you can use on your payment form. For more information, refer to Downloading logos.

You can also submit a /paymentMethods request specifying:

In the response, you receive paymentMethod.type: wechatpayWeb.

From your server, make a /payments request providing:

  • paymentMethod.type: wechatpayWeb

The /payments response contains an action object with the information needed to redirect the shopper.

/payments response
{
   "resultCode":"RedirectShopper",
   "action":{
      "paymentMethodType":"wechatpayWeb",
      "method":"GET",
      "url":"https://checkoutshopper-test.adyen.com/checkoutshopper/checkoutPaymentRedirect?redirectData=...",
      "type":"redirect"
   }
}

Handle the redirect

  1. To complete the payment, redirect the shopper to the action.url returned in the /payments response.
    When using the HTTP GET method:
    For security reasons, when displaying the redirect in the app, we recommend that you use SFSafariViewController for iOS or Chrome Custom Tabs for Android, instead of WebView objects. Also refer to the security best practices for WebView.
  2. After the shopper is redirected back to your website, check the payment result by making a POST /payments/details request, specifying:
    • details: Object that contains the URL-decoded redirectResult returned when the shopper was redirected back to your site.
    /payments/details request
    curl https://checkout-test.adyen.com/v67/payments/details \
    -H "x-API-key: YOUR_X-API-KEY" \
    -H "content-type: application/json" \
    -d '{
       "details": {
         "redirectResult": "eyJ0cmFuc1N0YXR1cyI6IlkifQ=="
     }
    }'

You receive a response containing:

  • resultCode: Use this to present the result to your shopper.
  • pspReference: Our unique identifier for the transaction.
    /payments/details response
    {
     "resultCode": "Authorised",
     "pspReference": "88154795347618C"
    }

Present the payment result

Use the resultCode that you received in the /payments/details response to present the payment result to your shopper.

The resultCode values you can receive for WeChat Pay are:

resultCode Description Action to take
Authorised The payment was successful. Inform the shopper that the payment has been successful.
You will receive the funds in 2-3 days.
Cancelled The shopper cancelled the payment while on the WeChat app. Ask the shopper whether they want to continue with the order, or ask them to select a different payment method.
Error There was an error when the payment was being processed. Inform the shopper that there was an error processing their payment. The response contains a refusalReason, indicating the cause of the error.
Pending or
Received
The payment order was successfully received. Inform the shopper that you've received their order, and are waiting for the payment to clear.
You will receive the final result of the payment in an AUTHORISATION notification. If successful, you will receive the funds in 2 days.
Refused The payment was refused by the shopper's bank. Ask the shopper to try the payment again using a different payment method.

Test and go live

WeChat Pay currently has no test platform. If you have a personal WeChat account you can test your integration by either:

  • Cancelling the transaction when you are asked to verify the payment (recommended).
  • Making live WeChat Pay payments with a low value.

You can check the status of a WeChat Pay payment in your Customer Area > Transactions > Payments.

Before you can accept live WeChat Pay payments, you need to submit a request for WeChat Pay in your live Customer Area.
