Not receiving Sandbox Server-to-Server Notifications for In-App Purchases (App Store Server Notifications v2)

I’m testing auto-renewable subscription purchases in the sandbox environment.

When I buy a subscription package using a sandbox test user, I don’t receive any App Store Server Notifications from the sandbox. However, when I use the “Request Test Notification” option in App Store Connect, the notification is received successfully.

My sandbox server notification URL is configured correctly and publicly accessible. I also call finishTransaction() after purchase, and the receipt is verified successfully with the sandbox verification endpoint.

To further debug, I used the getNotificationHistory API to fetch notifications for yesterday and today (Nov 3–4, 2025). Apple’s API response does not include any notifications or transaction IDs for my today’s purchases (Nov 4, 2025) — even though I can confirm from logs that those transactions were completed and verified successfully.

It looks like sandbox purchase notifications are not being sent or logged, even though test notifications work fine.

Could someone from Apple please confirm if there’s currently an issue with sandbox server notifications for auto-renewable subscriptions?

Getting the same issue here, system was working fine for sandbox notifications about 24 hours ago, but now I am not getting them sent.

Hello -

First, can you confirm that the test purchases being made are in the Sandbox environment, and not Xcode (if testing locally through Xcode) or Production? Ensure that the purchase payment confirmation sheet (the final step of the purchase flow) clearly indicates Sandbox.

If that is confirmed and you are still not seeing the notifications, please reply with your app name and the product(s) you have purchased in Sandbox - and we will investigate further on our end.

There are no known issues with Sandbox server notifications now or in recent days.

Thank you.

Hello,

Thank you for your response.

I can confirm that all test purchases are being made in the Sandbox environment, not via Xcode or Production. The purchase confirmation sheet clearly shows “Sandbox” during the final step of the purchase flow.

Our app is: Ollivate (app.ollivate.com) Sandbox test products purchased: [ollivate_crna_pro, ollivate.monthly.prod, ollivate_starter_prod_consumable]

Despite successful transactions and receipt verification via the sandbox endpoint, no App Store Server Notifications are received for today’s purchases. Only the test notifications sent via “Request Test Notification” are received successfully.

I also checked the Apple System Status page, and it indicates that there is currently an issue affecting the Sandbox environment. This seems consistent with the missing notifications we are experiencing.

Could you please investigate why sandbox server notifications are not being sent for these auto-renewable subscription purchases?

Thank you for your help.

Hi,

I have the same issue. I am not receiving any server to server notifications anymore in the sandbox environment. Last notification I received was yesterday evening November 3th ( UTC + 1 ).

Hi all,

I have exactly the same problem! I debugged today for hours why suddenly no sandbox notifications are sent anymore (I did not change anything in the code and the last time I tested it - the day before yesterday - it still worked perfectly). I could not find any reason and then I googled and found this forum entry with the exact same problem. Its definitely a global problem as I saw users posting in other forums as well.

Hi all,

I believe there is currently an issue with the Apple sandbox environment. You can check the system status here: https://developer.apple.com/system-status/

I can confirm im having the same issue. Auto renewable subscriptions are marked as "Your payment method was declined" and i dont receive any apple server notification to my sandbox url for initial purchase and upcoming events.

Test notifications are working fine for the sandbox url. When i check notification history, last notifications are from evening of November 3th (UTC).

Currently, i can only verify initial subscription receipt in my backend but notifications are not sent on sandbox environment. There has not been any change on application side.

Thanks in advance for any help or insight.
