About this skill
Problem
When integrating Douyin Pay, engineers often get stuck on product selection and documentation navigation: which of App, H5, JSAPI, or Native payments fits the target channel? Where do merchant parameters come from? How does payment continue when the Douyin client is not installed? This skill organizes the key entries from the Douyin Pay merchant documentation into a practical integration path, helping developers match business scenarios to products, prepare parameters, and move to the right docs.
How It Works
- Scenario routing: maps keywords such as
App payment,H5 payment,mini-program payment, andNative paymentto the recommended product. - Product scope: distinguishes native app payments, mobile web payments, Douyin mini-program payments, merchant QR-code payments, and refund flows.
- Preparation checklist: covers merchant onboarding and required fields such as
app_id,app_secret,merchant_id,private_key, andpublic_key. - App payment details: describes launching the Douyin client when available and guiding installation when it is missing; supports iOS, Android, and HarmonyOS.
- Documentation links: points to the merchant documentation center, open platform, and product-specific docs for deeper implementation.
Boundaries
This skill is specific to the Douyin payment ecosystem and does not cover Alipay, WeChat Pay, or UnionPay scenarios. It does not include capabilities such as merchant split payment or bank-card transfer. Use sandbox environments where available, and verify the latest official documentation before writing production code.
Use Cases
- Native app teams integrating Douyin payment on iOS, Android, or HarmonyOS need to choose the App payment flow.
- Mobile web projects need to display a cashier page in a phone browser and connect H5 payment.
- Douyin mini-program developers need to start JSAPI payment after order confirmation and return to the result page.
- Offline stores need to generate a merchant QR code so customers can scan and complete Native payment.
Best For
- Backend engineers choosing Douyin payment products and preparing integration parameters by scenario.
- Frontend engineers starting payments in H5 pages or mini-programs and handling payment redirects.
- Mobile engineers launching Douyin client payments inside native apps and covering missing clients.
- Tech leads verifying integration scope and excluding unsupported features like split payment or bank transfer.
