I started to get this error around 2 weeks after the integration.
When I run it on the device with a test user added I started to get this error.
I’m on Unity where I never got such an error with Unity IAP, but revenuecat is always gave headaches.
I assumed I don’t need to set up Storekit testing because I’m on real device. Right?
This is happening to me too, as described above.
ERROR: 
Product purchase for '#####' failed with error: Error Domain=RevenueCat.ErrorCode Code=8 "The receipt is not valid." UserInfo={NSUnderlyingError=0x600003718e70 {Error Domain=RevenueCat.BackendErrorCode Code=7103 "The receipt is not valid." UserInfo={rc_backend_error_code=7103, NSLocalizedDescription=The receipt is not valid.}}, source_file=RevenueCat/HTTPClient.swift:699, readable_error_code=INVALID_RECEIPT, source_function=parseUnsuccessfulResponse(), rc_response_status_code=400, rc_backend_error_code=7103, NSLocalizedDescription=The receipt is not valid.}
I’ve set everything up correctly (and no different to previous projects), but am having this error now. Am I alone?
When I try to make a purchase, it appears to go through fine, but then alerts me I have already made the purchase (even though on startup, my entitlements return empty). Once I press okay to restore my previous purchase, I get the receipt invalid prompt. And nothing seems to happen then. No customer purchase shows on the RC sandbox purchases screen.
I’m getting this error aswell. I’m testing on a physical device from Xcode. Purchase seems to go through ok, then I get the the error message ‘Purchase failed: Error 8, the receipt is not valid’ showing up, and purchase does not go through. I’ve tried signing in with a different sandbox account, and also changing the app-specific shared secret, as suggested above, and still get the same error.
I am using the purchases-capacitor plugin.
I see the below in the logs in Xcode.

I can also see this. I’m in process of evaluating Revenuecat on iOS and after successful transaction in sandbox I get error:
PlatformException(8, The receipt is not valid., {readable_error_code: INVALID_RECEIPT, message: The receipt is not valid., userCancelled: false, underlyingErrorMessage: The receipt is not valid., readableErrorCode: INVALID_RECEIPT, code: 8}, null)
I’m wondering if there is some issue in my setup or it’s sandbox/Apple fault.
RevenueCat isn’t able to resolve this at this time from our end, but it may help bring awareness and ease to other developers facing the same issue.
) reporting things are working as expected again - post below if you’re still having trouble, seems like a slow rollout of a fix from Apple.
