## What it is
go-iap is a Go library for verifying in-app purchase receipts across the Apple App Store, Google Play Store, Amazon AppStore, Huawei HMS, and Microsoft Store. It provides per-store client packages that validate purchase tokens and subscriptions server-side.

## Use cases
- verify iOS App Store purchase receipts in a Go backend
- validate Google Play subscription and product purchases
- check Amazon AppStore receipt validity
- verify Huawei HMS in-app purchases
- validate Microsoft Store purchases
- implement server-side in-app billing validation for mobile apps

## When to choose
- your backend is written in Go and needs multi-store receipt verification
- you support in-app purchases across multiple app stores and want one library
- you need App Store Server API support after verifyReceipt deprecation

## When to avoid
- your backend is not in Go
- you only need client-side purchase handling
- you need a billing UI or payment processing rather than receipt validation
