Purchase Validation

Purchase Validation is an optional, but recommended, module that standardizes in-app purchase verification across supported stores, including Apple App Store and Google Play. It simplifies receipt handling and validation by providing a consistent interface for verifying purchases and ensuring their integrity. Depending on your configuration, validation can be performed using Lion’s built-in validation service or third-party providers such as Adjust.

Purchase Validation is not intended to replace your game’s purchase flow. Instead, it works alongside your existing IAP implementation by handling store-specific validation requirements, reducing platform-specific logic, and minimizing boilerplate code needed to verify transactions.
