  • Create an In-App Purchase Key

Overview

To verify the authenticity of your affiliate sales (in-app purchases and subscriptions), GoMarketMe uses Apple’s In-App Purchase Key for secure server-to-server validation. Follow these five steps in App Store Connect to generate your In-App Purchase Key and upload it to GoMarketMe.

 

In-App Purchase Keys are used for StoreKit 2 receipts (Apple’s latest format). GoMarketMe must verify both StoreKit 1 and StoreKit 2 receipts. For StoreKit 1 receipts and App-Specific Shared Secret setup, visit https://gomarketme.co/documentation-service-credentials-app-store-connect/.
