## What it is
An elegant PHP payment SDK supporting Alipay, WeChat Pay, UnionPay (Unipay), Douyin Pay, and Jiangsu Bank e-payment gateways. It features a flexible plugin mechanism, event system, multi-tenant support, and PSR-compliant design, with dedicated Laravel and Hyperf extension packages.

## Use cases
- integrate alipay and wechat pay into a php application
- accept wechat mini program payments
- process refunds and query orders across multiple payment gateways
- add unionpay qr code payments to an e-commerce site
- handle payment callbacks and signature verification
- support multiple merchants with multi-tenant payment config
- accept douyin mini program payments

## When to choose
- you are building a PHP application that needs Chinese payment gateways like Alipay or WeChat Pay
- you want a unified API across multiple payment providers instead of integrating each SDK separately
- you use Laravel, Hyperf, or Yii and want a ready-made integration package
- you need multi-tenant payment support or Swoole compatibility

## When to avoid
- your project is not in PHP
- you need payment gateways outside China such as Stripe or PayPal
- you are still on the end-of-life v1.x version and cannot migrate

## Facets
- artifact type: library
- maturity: stable
- function: sdk, developer-tools, security
- domain: fintech, e-commerce, web-development, backend
- platform: php, self-hosted
