Hi everyone, I’ve been encountering a recurring issue with the App Store Server API over the past 48 hours, specifically regarding the Get Transaction Info endpoint. Endpoint: GET /inApps/v1/transactions/{transactionId} Environment: Production Error Code: 4040010 (TransactionIdNotFound) The Issue When a user completes a purchase in our app, the client-side sends the transactionId to our backend for validation. However, when our server immediately calls the Get Transaction Info API using that ID, it frequently returns a 4040010 error, stating that the transaction ID cannot be found. Key Observations Eventual Consistency Delay: If we implement a retry logic and wait for 2 to 5 minutes, the exact same transactionId eventually becomes queryable and returns a valid signedTransactionInfo. Notifications vs. API: Interestingly, our server receives the App Store Server Notifications V2 (webhook) for these transactions almost instantly. The notifications contain the correct data, but the "Pull" API seems to lag behind the "Push" notification system. Recent Spikes: This behavior started occurring frequently within the last 2 days. Prior to this, the API was almost always near-instant. Questions Has anyone else noticed a spike in 4040010 errors or increased indexing latency in the Production environment recently? Is there a recommended "grace period" or backoff strategy when querying for a new transactionId? Apple's documentation doesn't explicitly mention an expected delay between a successful purchase and its availability via the Server API. Any insights or confirmation of similar issues would be greatly appreciated!

Hey We have noticed a change in the retry behavior of Apple Server Notifications webhooks V2 starting around March 12–13, 2026. Previously, when our webhook endpoint returned an HTTP 400 response, Apple would retry the notification delivery multiple times according to the documented retry policy. However, beginning around March 12–13, it appears that Apple no longer retries the webhook when a 400 response is returned. The notification is sent only once and no further retry attempts are made. From our understanding of the documentation, retries should occur when delivery fails, and historically we observed retries even for some 4xx responses. We would like to confirm: Has Apple recently changed the retry behavior for Server Notifications? Are HTTP 4xx responses (specifically 400) now considered terminal failures that will not trigger retries? Is this change intentional or related to a rollout in the webhook delivery system? We have called the "Notification History" endpoint for some users who purchased a sub and we are only getting one attempt with the following data in it: { attemptDate: 1773469202552, (2026-03-14T06:20:02.552Z) sendAttemptResult: 'UNSUCCESSFUL_HTTP_RESPONSE_CODE', } This was 2 days ago, based on the docs, the user should have a few attempts at least. This behavior change affects systems that rely on retries to handle temporary validation issues or transient failures. Thanks!
