Use WeChat Pay

Overview

Place an order for catalog products defined in your Control Panel and collect the payment using WeChat Pay.

Requirements

Only Chinese shoppers are able to purchase using WeChat Pay. Make sure the billing country code is set to CN.

Supported currencies

  • USD
  • HKD
  • CNY

Workflow

  1. Shoppers select WeChat as payment option in the interface you provide to them.
  2. Create the order object. Use WE_CHAT_PAY as the type of the PaymentDetails object, and include ReturnURL and CancelURL.
  3. Use the placeOrder method to send the data to Avangate.
  4. Once you place the order, Avangate logs it into the system. At this point in time, the status of the order is PENDING.
  5. Avangate returns an Order object as the output of the placeOrder method. 
  6. Use the PaymentMethod object to create a redirect URL for the shoppers, concatenating the values of the Href and avng8apitoken parameters. Here's an example of the redirect URL:
    https://api.avangate.com/4.0/scripts/we_chat_pay/authorize/?avng8apitoken=1abc7fd72d008428
  7. After being redirected to WeChat Pay, shoppers need to scan the QR code provided, using the WeChat smartphone app.
  8. After customers enter their payment password, WeChat notifies Avangate if the payment is approved, and the status of the order becomes COMPLETE.
  9. Shoppers are redirected to the RedirectURL from the Order information object. In case the payment fails, shoppers are redirected to the CancelURL.
