Receipt Validator – Secure, Server-Side IAP Validation

If you are looking for ways to secure your app against fraudulent and hacked in-app purchases, look no further. From the developer of Simple IAP System comes the Receipt Validator, a secure, high-grade cloud computing service for validating your in-app purchases. Always retrieve the latest state of your products and inform users about expiring subscriptions or billing issues.

Includes a free tier to get started. Currently supports Google Play and Apple App Store using Unity IAP. If you are using a different billing plugin, let me know!
