Enable WeChat Pay for in-app payments

Before you can start accepting WeChat Pay in-app payments, you need to:

• Create a developer account on the WeChat Open Platform.
• Register your mobile app with WeChat.

Additionally, if you prefer to build your own WeChat Pay integration and not use our existing Drop-in or Component, you need to:

• Integrate WeChat's mobile SDKs.

Create a WeChat developer account

To register a WeChat Developer Account:

1. Go to https://open.weixin.qq.com/ and select Sign Up.
2. Fill in your information and complete your developer profile.

WeChat will contact you to verify that the details you provided are correct. Once approved, you can register your mobile app.

Register mobile app

To register your Android app with WeChat:

1. Go to https://open.weixin.qq.com/ and click Log In .

2. Navigate to Admin Center > Mobile Application > Create Mobile Application, and enter the following for your app:

   1. Name.
   2. Short introduction.
   3. The official website.
   4. iOS only: The App Store download link and Bundle ID. The Bundle ID is usually in the format com.your-company.app-name

   When your app is successfully registered, you'll receive an AppID and AppSecret from WeChat.

3. Contact our Support Team, and provide them your AppID and AppSecret. This will ensure that payments made with your app are settled to your Adyen account.
