1. Introduction
In-app purchase validation library for Apple AppStore and GooglePlay (App Store validator have async support!).
2. Installation
pip install inapppy

# signature means `signatureAndroid` in result of purchase

Alternative to .verify method, instead of raising an error result class will be returned.
