Accept WeChat Pay with a server-side-only integration
Build your own payment form to add WeChat Pay to your checkout page
Overview
WeChat Pay doesn’t require any input from the customer on the merchant website. The customer will specify the required payment information on the WeChat Pay platform.
Before you begin
- Follow the steps in Get started guide to setup your environment.
- Familiarize yourself with the general Server side-only integration guide.
Step 1: Create a Payment Type resource server side
When creating the payment type WeChat Pay, you need to send a request to the Unzer API. The response will contain an id
, later referred to as typeId
. You need this typeId
to perform the transaction.
POST https://api.unzer.com/v1/types/wechatpay
Body: {}
$unzer = new UnzerSDK\Unzer('s-priv-xxxxxxxxxx');
$wechatpay = new UnzerSDK\Resources\PaymentTypes\Wechatpay();
$wechatpay = $unzer->createPaymentType($wechatpay);
Wechatpay wechatpay = new Wechatpay();
Unzer unzer = new Unzer(new HttpClientBasedRestCommunication(), "s-priv-xxxxxxxxxx");
wechatpay = unzer.createPaymentType(wechatpay);
The response will look similar to the following example:
{
"id": "s-wcp-otvqlpgqsh7u",
"method": "wechatpay",
"recurring": false,
"geoLocation": {
"clientIp": "127.0.0.143",
"countryCode": "DE"
}
}
