Purchase verification

If you’ve enabled purchase verification, you must send additional information with your purchase events to verify them. When Adjust’s servers receive this information in an ADJEvent object, they forward it to Apple to verify the purchase.

To verify a purchase, instantiate an ADJEvent object with your event token and set the following properties:

transactionId (NSString): The transactionIdentifier value of the successfully completed purchase
productId (NSString): The product identifier of the item that was successfully purchased
receipt (NSData): The signed receipt containing the information about the successfully completed purchase

Swift
Objective-C

1
let receiptURL = Bundle.main.appStoreReceiptURL;
2
let receipt = try Data(contentsOf: receiptURL, options: .alwaysMapped)

4
let event = ADJEvent(eventToken: "abc123")
5
event?.setRevenue(6.0, currency: "EUR");
6
event?.setTransactionId("transaction-id");
7
event?.setProductId("product-id");
8
event?.setReceipt(receipt);
9
Adjust.trackEvent(event)

1
NSURL *receiptURL = [[NSBundle mainBundle] appStoreReceiptURL];
2
NSData *receipt = [NSData dataWithContentsOfURL:receiptURL];
3
ADJEvent *event = [ADJEvent eventWithEventToken::@"your-event-token"];
4
[event setRevenue:6.0 currency:@"EUR"];
5
[event setTransactionId:@"transaction-id"];
6
[event setProductId:@"product-id"];
7
[event setReceipt:receipt];
8
[Adjust trackEvent:event];
