Sending in-app purchases on iOS

For the AppMetrica SDK version 4.0 and higher, automatic collection of data about purchases within the app is available. To enable and disable automatic collection, use the revenueAutoTrackingEnabled ( Objective-C | Swift ) property.
  1. Testing and manually sending purchase information
  2. Step 1. Create a test app in AppMetrica
  3. Step 2. (Optional) Enable validation
  4. Step 3. Test sending Revenue
  5. Step 4. Make sure that purchases are shown in reports.
  6. Step 5. Set up sending Revenue to the main API key

Testing and manually sending purchase information

AppMetrica doesn't let you segment Revenue into “test” and “not test”. If you use the main API key for debugging purchases, the test purchases are included in general statistics. If you need to debug sending Revenue, use a reporter to send statistics to an additional API key. For more information about reporters, see Usage examples.

Step 1. Create a test app in AppMetrica

Specify the app parameters: link in the app store (if the app hasn't been published yet, leave the field empty), name, category, and time zone for generating reports.

To add another app, click Add app in the drop-down list in the AppMetrica interface.

Step 2. (Optional) Enable validation

Purchases on iOS are validated using iTunes API resources.

To enable validation:
  1. In the AppMetrica interface, go to the app settings from the menu on the left.
  2. Go to the Revenue tab.
  3. Under Revenue validation for App Store, click Enable validation.
Attention. If validation is enabled, the Revenue report displays purchases that were validated or were sent without the transactionID and receiptData fields.

Step 3. Test sending Revenue

This section outlines the steps for sending Revenue to the additional API key:

To validate purchases on iOS, configure sending the transactionID and receiptData fields in the implementation of the completion of the transaction:

- (void)completeTransaction:(SKPaymentTransaction *)transaction
{
    ...
    NSDecimalNumber *price = [NSDecimalNumber decimalNumberWithString:@"2100.5"];
    // Initializing the Revenue instance.
    YMMMutableRevenueInfo *revenueInfo = [[YMMMutableRevenueInfo alloc] initWithPriceDecimal:price currency:@"BYN"];
    revenueInfo.productID = @"TV soundbar";
    revenueInfo.quantity = 2;
    revenueInfo.payload = @{ @"source": @"AppStore" };
    // Set purchase information for validation.
    revenueInfo.transactionID = transaction.transactionIdentifier;
    revenueInfo.receiptData = [NSData dataWithContentsOfURL:[[NSBundle mainBundle] appStoreReceiptURL]];
    // Sending the Revenue instance using reporter.
    id<YMMYandexMetricaReporting> reporter = [YMMYandexMetrica reporterForApiKey:@"Testing API key"];
    [reporter reportRevenue:[revenueInfo copy] onFailure:^(NSError *error) {
        NSLog(@"Revenue error: %@", error);
    }];
    // Remove the transaction from the payment queue.
    [[SKPaymentQueue defaultQueue] finishTransaction: transaction];
}

Step 4. Make sure that purchases are shown in reports.

  1. Make in-app test purchases.
  2. Make sure that the Revenue report shows the same number of purchases and total revenue as the ones sent.

    Information in the report may be missing if:

    • Validation is enabled and the purchase failed.
    • Information about the purchase wasn't sent.
  3. If there is no data in the report, export all purchases using the Logs API resource:

    curl -X GET \
      'https://api.appmetrica.yandex.ru/logs/v1/export/revenue_events.json?application_id=1111&date_since=2018-10-10&date_until=2018-10-11&fields=revenue_order_id,revenue_quantity,revenue_price,revenue_currency,is_revenue_verified' \
      -H 'Authorization: OAuth oauth_token'
    Copied to clipboard
    If there are events in the export and the is_revenue_verified field is set to false, the purchases weren't validated.

Step 5. Set up sending Revenue to the main API key

After debugging, repeat steps 2-4 for the main API key.

To send the YMMMutableRevenueInfo instance to the main API key, use the +reportRevenue:onFailure: method of the YMMYandexMetrica class.

To send the YMMMutableRevenueInfo instance to the main API key, use the +reportRevenue:onFailure: method of the YMMYandexMetrica class.

...
// Sending the Revenue instance.
YMMYandexMetrica.reportRevenue(revenueInfo, onFailure: { error in
    print("Revenue error: \(error)")
})
