Set up App Store Server Notifications V2 and route them to Slack

Set up App Store Server Notifications V2 and route subscription events, refunds, and in-app purchase alerts to Slack with full context. Four steps with Yeethook.

What Are App Store Server Notifications V2


App Store Server Notifications V2 (ASN V2) are Apple's system for notifying your server about in-app purchase and subscription lifecycle events. They cover subscriptions, refunds, offer redemptions, revocations, and more. Setting up App Store Server Notifications V2 correctly is essential for any app with subscriptions or in-app purchases.


The Problem


Setting up and processing these notifications requires:

  • A server endpoint that handles JWS-signed payloads.
  • Signature verification against Apple's certificate chain.
  • Parsing logic for every notification type and subtype.
  • A way to display or store the information.

Most teams either skip server notifications entirely or build fragile custom solutions.
