App Store conversion tracking
App Store conversion tracking is the practice of tying an iOS app install or in-app purchase back to the marketing that drove it, using Apple's own server-side signals rather than device fingerprinting.
Since iOS 14.5, device fingerprinting for attribution is against Apple's rules, and web affiliate tools cannot see what happens inside the App Store. That leaves most affiliate-driven installs and subscriptions invisible.
Attribloom tracks them with two Apple mechanisms: a StoreKit 2 appAccountToken minted at purchase and App Store Server Notifications v2 that confirm the transaction server side.
Frequently asked
Can I track App Store subscriptions without a receipt-validation SDK?
Yes. Using the StoreKit 2 appAccountToken plus App Store Server Notifications v2, the subscription is confirmed server side without shared-secret receipt validation.
Why can regular affiliate tools not see App Store conversions?
Web affiliate tools rely on browser cookies and pixels at checkout. App Store purchases happen inside Apple's system, so those signals never fire.
