## What it is
A Node.js module for validating in-app purchase receipts and managing subscriptions across Apple App Store, Google Play, Amazon, Roku, and Windows, with Unity receipt support. It supports both Promise and callback APIs and Google Service Account-based validation.

## Use cases
- validate iOS App Store receipts in Node.js
- verify Google Play in-app billing purchases
- manage subscription status for mobile apps
- validate Unity IAP receipts server-side
- check Amazon and Roku purchase receipts
- validate subscriptions with Google service account

## When to choose
- you need a single Node.js library to validate receipts across multiple app stores
- your backend is JavaScript/Node.js and handles mobile subscription validation

## When to avoid
- you need official first-party SDK support or guaranteed long-term maintenance
- your stack is not Node.js
- you need purchase validation for stores not covered by this module

## Facets
- artifact type: library
- maturity: maintenance
- function: auth, sdk, form-handling
- domain: mobile-development, fintech, apis, backend
- platform: cross-platform
- tags: in-app-purchase, receipt-validation, subscriptions, google-play, app-store, unity-iap, roku, amazon-store, nodejs
