[Register your mobile app](/payment-methods/wechat-pay/wechat-pay-in-app-payments/enable-wechat-pay#register-mobile-app) with WeChat. 3. In Xcode, go to **File** > **Project Settings** > **App Target** > **Info**, and: 1. Under **URL Types**, go to **URL Schemes**, and add your registered WeChatPay app ID with identifier **weixin** . 2. Go to **LSApplicationQueriesSchemes**, and add: * **weixin** * **weixinULAPI** * **weixinURLParamsAPI** 4. Add WeChat Pay to CocoaPods or Carthage. **CocoaPods** Add `pod 'Adyen/WeChatPay'` to your `Podfile`. **Carthage** Add `AdyenWeChatPay.framework` to: * `app "build settings"/"Build Phases"/"Embed Frameworks"`. * `app "build settings"/"Build Phases"/"Link Binary to Libraries"`. * `app "build settings"/"Build Phases"/"Dependencies"`. ## API reference You do not need to send additional fields for WeChat Pay. To see optional fields that you can send for all payment methods, choose the endpoint you integrated: * [/sessions](https://docs.adyen.com/api-explorer/Checkout/latest/post/sessions): This is the default with [Drop-in v5.0.0](/online-payments/build-your-integration/sessions-flow?platform=iOS\&integration=Drop-in) or later. * [/payments](https://docs.adyen.com/api-explorer/Checkout/latest/post/payments): If you implemented an [additional use case](/online-payments/build-your-integration). ## Drop-in configuration ### Tab: v5.0.0 or later There is no required WeChat Pay-specific integration for Drop-in. ### Tab: v4.x.x There is no required WeChat Pay specific integration for Drop-in. ## 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: * Canceling 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](https://ca-live.adyen.com/) > **Transactions** > **Payments**. Before you can accept live WeChat Pay payments, you need to submit a request for WeChat Pay in your [live Customer Area](https://ca-live.adyen.com/). ## See also * [iOS Drop-in integration guide](/online-payments/build-your-integration/sessions-flow?platform=iOS\&integration=Drop-in) * [iOS Reference](https://adyen.github.io/adyen-ios/5.0.0/documentation/adyen/) * [Tokenization](/online-payments/tokenization) * [API Explorer](https://docs.adyen.com/api-explorer/#/CheckoutService/latest/overview)
