Getting 21002 from Apple when verifying transactionReceipt

Description

Getting { 'status': 21002 } responses when calling /verifyReceipt with transactionReceipt.

Expected Behavior

/verifyReceipt should work.

Environment:

• react-native-iap: 12.10.5
• react-native: 0.71.7
• Platforms (iOS, Android, emulator, simulator, device): iOS

To Reproduce
Steps to reproduce the behavior:

The sequence flow I use is as follows:

1. requestSubscription on button click
2. purchaseUpdatedListener gets triggered with a purchase object
3. I call validateReceipt which is a method that sends the following to my web server:

{
        receipt: purchase.transactionReceipt,
        platform: Platform.OS,
        subscriptionId: purchase.productId,
        token: purchase.purchaseToken
}

4. My web server makes a call to /verifyReceipt with the following request body:

{
    "receipt-data": transactionReceipt,
      "password": SECRET
      "exclude-old-transactions": true,
}

5. Apple responds with { "status": 21002 }.

This worked until recently when I upgraded expo, react native and react-native-iap.

same problem here @andresesfm

Check the receipt is properly encoder in base 64

[AaronCCWong]

This is a value that is returned through this library. That is, we get it from the purchase parameter of purchaseUpdateListener. If that returns a string that isn't properly base64 encoded, is there anything we can do on our end to make sure that it is?

@andresesfm Experiencing this same issue. The value in currentPurchase.transactionReceipt is malformed. We are receiving this value from the library itself, so it should be in proper Base64 format.

I am currently using requestSubscription and then using currentPurchase to send a validation request to my apple sandbox /verifyRequest using transactionReceipt. My subscription plans are loaded from Storekit config.

[andresesfm]

Look at ios/RNIapIos.swift:322. It is bein encoded there using base64EncodedString. Maybe play around with removing/changing the options argument

[numsu]

Having the same issue. Value returned by this library and passed on to Apple as-is in the backend.

[midhunevolvier]

Does anyone have the solution? I am stuck.

[numsu]

I decided to change my implementation because of this. Now I am sending the appAccountToken which contains an uuid of the purchase to Apple and verifying that the purchase is successful by verifying that in the S2S payload. Not handling receipts at all.

This is also happening to me, has anyone gotten a solution? @numsu do you have any details on how you were able to get that information?

[numsu]

This is also happening to me, has anyone gotten a solution? @numsu do you have any details on how you were able to get that information?

1. Generate an unique identifier on the client or your backend server once the user presses the "Buy" button and store it to your DB
2. Set the generated identifier to the appAuthToken field with this library
3. If the user completed the purchase, you will receive a S2S notification from Apple, if you have set it up. The payload will include your appAuthToken. Set the status of the purchase based on this notification

I was also facing the issue earlier but it was solved by making some changes to the way I was passing the parameter to the validateReceiptIos. before I was passing it as "RNIap.validateReceiptIos(receiptBody, true)". but now I have made the changes and called it like this "RNIap.validateReceiptIos({receiptBody: receiptBody, isTest: true})" and It started working properly .

Sorry to bother @numsu but I cannot seem to get Apple Store Server Notifications. The server url never gets called, the setup is alright as i used the test endpoint and the notification arrived properly
Do you have any idea what I'm doing wrong?

confirm the same issue "react-native-iap": "^12.12.2",

[hotaryuzaki]

confirm the same issue "react-native-iap": "^12.13.0",

i think one of the reasons this issue is rising is because the docs are not giving the right suggestions.
i solved with this useEffect

  useEffect(() => {
    const subscription = purchaseUpdatedListener((purchase) => {
      // console.log('>>> APP JS useEffect purchaseUpdatedListener', purchase.transactionReceipt);

      const verify = async purchase => {
        const verifyPurchase = await validateReceiptIos({
          receiptBody: { 'receipt-data': purchase.transactionReceipt },
          isTest: true
        });
      }

      verify(purchase);
    });

    return () => {
      subscription.remove();
    };
  }, []);

and another issue is that the name of the functions in the docs is wrong, it took me hours to realize this.
validateReceiptIos => in the docs is validateReceiptIOS

and another issue requestPurchaseWithQuantityIOS is undefined which i reported here
