## [App-Specific Shared Secret](/docs/service-credentials/itunesconnect-app-specific-shared-secret)

The App-Specific Shared Secret is a unique authentication key that allows RevenueCat to securely communicate with Apple's servers on your behalf. This secret is mandatory for receipt validation when using StoreKit 1.

## [In-App Purchase Key](/docs/service-credentials/itunesconnect-app-specific-shared-secret/in-app-purchase-key-configuration)

When configuring a new App Store app in your RevenueCat project, you will need to add an in-app purchase key. This is a required configuration step. When using Purchases v5.x+ (i.e., StoreKit 2), transactions will fail to be recorded without this key being set. This can result in users not accessing the purchases they are entitled to.

## [App Store Connect API Key](/docs/service-credentials/itunesconnect-app-specific-shared-secret/app-store-connect-api-key-configuration)

You may upload an App Store Connect API key for RevenueCat to import products and prices from App Store Connect.
