## What it is
GoPay is an aggregated payment SDK for Go that wraps WeChat Pay, Alipay, Douyin Pay, PayPal, Apple Pay, QQ Pay, Allinpay, Lakala, CMB, and Saobei behind a simple unified API. It provides clients, request/response handling, and documentation for integrating multiple Chinese and international payment platforms into Go backend services.

## Use cases
- integrate wechat pay v3 into a go backend
- accept alipay payments in a golang web service
- verify apple in-app purchase receipts in go
- add paypal checkout to a go application
- support douyin pay in a mini-program backend
- unify multiple payment providers behind one sdk
- handle merchant transfer APIs for wechat

## When to choose
- you need to integrate Chinese payment platforms (WeChat, Alipay, Douyin) in Go
- you want one SDK covering many payment providers instead of writing API clients yourself
- you need actively maintained payment SDK with docs and examples

## When to avoid
- your project is not in Go
- you need a full payment orchestration or billing platform rather than an API SDK
- you require payment providers not covered by the library
