Is There A Way To Get Notified When Someone Makes An In-App Purchase?

Question

I\'d like to be notified when someone makes an In-App Purchase in my App rather than wait until the next day to check iTunes Connect to see wether or not I had any sales.

Track StoreKit Purchase Events

When a purchase takes place, send yourself a datapoint (Track here...)

func paymentQueue(_ queue: SKPaymentQueue, updatedTransactions transactions: [SKPaymentTransaction]) {
    for transation in transactions {
        switch transation.transactionState {

            case .purchased:
                queue.finishTransaction(transation)
                // Track here...

            case .purchasing: break
            case .restored: break
            case .deferred: break
            case .failed: break
        }
    }
}

(*) Provides support for WiFi reporting (allows to postpone all reporting until WiFi network is available, as to not use cellular data). See mixpanelWillFlush below.

NSDictionary *dimensions =
    @{@"productIdentifier":@(t.payment.productIdentifier)};
[PFAnalytics trackEvent:@“Purchase” dimensions:dimensions];

Send an email from a server

POST purchase to a URL, and have in turn the server send you a mail or other notification.

iOS implementation using URLSession:

if let url = URL(string: "https:///php/purchase.php") {
    var request = URLRequest(url: url)
    request.httpMethod = "POST"
    request.httpBody =
        "{\"productIdentifier\":\"\(transaction.payment.productIdentifier)\"}"
        .data(using: .utf8)
    request.addValue("application/json", forHTTPHeaderField: "Content-Type")
    request.addValue("application/json", forHTTPHeaderField: "Accept")
    let task = URLSession.shared.dataTask(with: request as URLRequest,
                                          completionHandler: {_,_,_ in })
    task.resume()
}
