Get wrong receipt data from Apple

Question

I have been stuck on this issue for a long time. I'm a newer in Swift and I couldn't find a way to solve this problem.

I got the receipt data from my App, the code is,

if let appStoreReceiptURL = Bundle.main.appStoreReceiptURL, FileManager.default.fileExists(atPath: appStoreReceiptURL.path) {
    do {
        let receiptData = try Foundation.Data(contentsOf: appStoreReceiptURL, options: .alwaysMapped)
        print(receiptData)
        
        &#x2F;&#x2F; Read ReceiptData
        print("receipt: \(receiptData.base64EncodedString(options: []))")
    }
    catch { print("Couldn&#039;t read receipt data with error: " + error.localizedDescription) }
}

which is copied from sample code from Apple Developer Document.

And this is one of the receipt data got from sandbox environment,

But when I use it to verify in sandbox environment, I always got 21002 error.

Then I found some receipt data from stackoverflow https://stackoverflow.com/questions/33843281/apple-receipt-data-sample/53286406#53286406 .

I use them to test my python code, it works. Here is the python code,

receipt = "xxxxxx"
url = &#039;https:&#x2F;&#x2F;sandbox.itunes.apple.com&#x2F;verifyReceipt&#039;
headers = {"Content-type": "application&#x2F;json"}
data = json.dumps({"receipt-data": receipt})
res = requests.post(url=url, 
                    data=data, 
                    headers=headers, 
                    verify=False).text
print(res)

So, it seems that it's the receipt data I got from Apple wrong.

I don't know why the receipt data is wrong. Is there anyway to find out the problem?

I'm using XCode (Version 14.1 beta 2 (14B5024i)) and a iphone SE to make a test. It purchased and verified according to StoreKit 2.

Answer 1

You are using a locally created Storekit configuration file, is that right? This receipt is created and signed by your local Xcode machine, not the App Store itself, therefore it will not function with Verify Receipt. Use an app through Sandbox/TestFlight to get a receipt from the App Store.

Thanks for your reply. As you mentioned, I'm using a local storekit configuration file. But I didn't find any description about the difference between using local configuration file and receipt from Apple store. Is there any document about this? Or will it be better if we added some description to this document: https://developer.apple.com/documentation/storekit/in-app_purchase/implementing_a_store_in_your_app_using_the_storekit_api ?

See the table in https://developer.apple.com/documentation/storekit/in-app_purchase/testing_at_all_stages_of_development_with_xcode_and_the_sandbox called Test environment. You'll see that "Provides receipts and JSON Web Signature (JWS) transactions signed by the App Store" is false for "StoreKit testing in Xcode".
