App Store Connect Help
Generate a shared secret to verify receipts
To increase the security between your server and Apple’s servers when validating an App Store subscription or in-app purchase, include a shared secret with your request to verify receipts.
A shared secret is a 32 character hexadecimal string generated in App Store Connect. You may generate a primary shared secret, which is single code for all of your apps, or an app-specific shared secret for individual apps. You may also use a primary shared secret for some of your apps, and an app-specific shared secret for others.
For information about incorporating a shared secret into your app’s receipt handling, visit Validating Receipts with the App Store.
