In-App Purchase Validation

This document provides guidelines and instructions for validating In-App Purchases on your server. This server-side validation is optional, as purchase validation is already performed on the client by the AppCoins SDK.

For iOS integration, there is only one server validation option available: Remote Check. Remote Check involves sending transaction information to remote servers for validation.

Remote Check

Your server must be able to receive the necessary information from your application, send it to our server for validation, process the response from our server, and relay the appropriate result back to your application.
