Route every App Store Server Notification to Slack

What Are App Store Server Notifications V2

App Store Server Notifications 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.

The Problem

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.

The Solution

Yeethook handles the entire pipeline:

1. Receives the signed notification from Apple.
2. Parses the payload, extracting the notification type, subtype, and transaction info.
3. Enriches the data (with a p8 key) by calling Apple's APIs for additional context.
4. Formats a readable Slack message with all relevant details.
5. Delivers it to the right Slack channel based on your routing rules.

Supported Notification Types

All 18+ App Store Server Notification V2 types are supported, including:

• Subscription lifecycle (SUBSCRIBED, DID_RENEW, EXPIRED, etc.)
• Billing issues (DID_FAIL_TO_RENEW, GRACE_PERIOD_EXPIRED)
• Refunds (REFUND, REFUND_DECLINED, REFUND_REVERSED)
• Offers (OFFER_REDEEMED, PRICE_INCREASE)
• Revocations (REVOKE)
• External purchases (EXTERNAL_PURCHASE_TOKEN)

2. Upload your p8 key — Yeethook registers the notification URL with Apple automatically.

4. Connect Slack and route events to your channels.
