App Store Server API reference for the apple plugin — look up in-app purchase transactions, subscription status, order IDs, refunds, server notification history, test notifications, and decode signed JWS payloads (signedPayload, signedTransactionInfo). Load for customer-support investigations on purchases or StoreKit server work (storekit_* tools).

The file

We split this skill into the rules it gives an agent

2 rules. About 0 are common, 0 are distinctive, and 2 are very specific to this project.

    Many files like this have a rule of this kind.

    Distinctive · estimate

    This author's own choices. Worth a look.

  • 2

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  2. Very specific:

    Customer says "I paid but…": ask for the order id from their receipt e-mail → storekit_order_lookup (status 0 = valid) → transaction ids → …

≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

App Store Server API (tools storekit_*, apple_jws_decode)

Auth: ES256 JWT from app_store_server.key_id/issuer_id/private_key with bid = bundle id (In-App Purchase key from App Store Connect → Integrations). Hosts: production api.storekit.itunes.apple.com, sandbox api.storekit-sandbox.itunes.apple.com (environment param or config). A transaction only exists in one environment: if production returns 404 TransactionIdNotFound, retry with environment: sandbox.

All signed fields (signedTransactionInfo, signedRenewalInfo, signedPayload, signedTransactions[]) are decoded automatically (signature not verified — the server trusts Apple's TLS endpoint; for webhook payloads received from third parties verify the x5c chain against Apple Root CA G3 before trusting).

Tasks

  • Customer says "I paid but…": ask for the order id from their receipt e-mail → storekit_order_lookup (status 0 = valid) → transaction ids → storekit_history / storekit_subscriptions.
  • Subscription state: storekit_subscriptions → per group: status 1 active, 2 expired, 3 billing retry, 4 grace period, 5 revoked; renewalInfo.autoRenewStatus, expirationIntent, gracePeriodExpiresDate, priceIncreaseStatus, offer fields.
  • Refunds: storekit_refund_history (revocationDate/revocationReason on transactions).
  • Did we receive the webhook? storekit_notification_history for a date range (ms epoch; ≤180 days back), filter notificationType (SUBSCRIBED, DID_RENEW, DID_CHANGE_RENEWAL_STATUS, EXPIRED, GRACE_PERIOD_EXPIRED, REFUND, REFUND_DECLINED, CONSUMPTION_REQUEST, RENEWAL_EXTENDED, PRICE_INCREASE, OFFER_REDEEMED, ONE_TIME_CHARGE, TEST…) or transaction_id; storekit_test_notification fires a TEST notification to the configured URL and reports delivery.
  • Consumption info for refund requests: storekit_request PUT /inApps/v1/transactions/consumption/{transactionId} with {"customerConsented": true, "consumptionStatus": 1, "platform": 1, "sampleContentProvided": false, "deliveryStatus": 0, "appAccountToken": "", "accountTenure": 4, "playTime": 0, "lifetimeDollarsRefunded": 0, "lifetimeDollarsPurchased": 3, "userStatus": 1, "refundPreference": 0}.
  • Extend a renewal (goodwill): storekit_request PUT /inApps/v1/subscriptions/extend/{originalTransactionId} {"extendByDays": 7, "extendReasonCode": 1, "requestIdentifier": "<uuid>"}; mass extension: POST /inApps/v1/subscriptions/extend/mass.
  • Transaction fields: transactionId, originalTransactionId, webOrderLineItemId, productId, type (Auto-Renewable Subscription, Non-Consumable, Consumable, Non-Renewing Subscription), purchaseDate/expiresDate (ms + _iso), environment, storefront, price (milli-units) + currency, offerType/offerDiscountType, transactionReason (PURCHASE, RENEWAL), inAppOwnershipType (PURCHASED, FAMILY_SHARED), appAccountToken.
  • apple_jws_decode also decodes Sign in with Apple id_tokens and StoreKit 2 jwsRepresentation.

Your trail

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
