hi! I used this URL too for verifying the receipts: https://sandbox.itunes.apple.com/verifyReceipt I have also added the password (app's shared secret key) but still the return of the request is 21002. I have tried changing the encoding options from 0 to EndLineWithCarriageReturn -> NSString *base64Receipt = [receiptData base64EncodedStringWithOptions:NSDataBase64EncodingOptions.EncodingEndLineWithCarriageReturn]; Do you know what else can I do? Thank you so much! This would be a big help!

@vincent123 yes, this is my current code right now NSString *base64Receipt = [receiptData base64EncodedStringWithOptions:0]; NSDictionary *requestContents = @{@"receipt-data": base64Receipt,@"password": @""}; NSError *error; NSData *requestData = [NSJSONSerialization dataWithJSONObject:requestContents options:0 error:&error];} and pass it to the URL: [request setHTTPMethod:@"POST"]; [request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"]; [request setHTTPBody:requestData];

hi again! @vincent123 I have a question, I think I feel like I know why it always returns 21002, but I am not really sure. Right now, I am testing the In app purchases and subscriptions through storekit configuration file. So the receipts are generated from storekit config file. Is it not possible to validate receipts from storekit configuration with xcode? Should I always test with sandbox for validation of receipts? Thank you so much!

@vincent123 This is noted. I have not tried using sandbox yet, but thank you so much for this!

Noted. Thank you so much!

This is noted. But I have a question. In terms of the Vary by Plural/ Device in String Catalogs, is this also applicable with storyboards localization strings? Thank you so much!
