Ecommerce Tracking

This document provides an overview of how to measure in-app payments and revenue using the Google Analytics SDK v4 for Android.

Overview

Ecommerce measurement allows you to send in-app purchases and sales to Google Analytics. Ecommerce data in Google Analytics is comprised of transaction and item hits, related by a shared transaction ID.

Transactions have the following fields:

Field Name	Type	Required	Description
Transaction ID	`String`	Yes	A unique ID representing the transaction. This ID should not collide with other transaction IDs.
Affiliation	`String`	Yes	An entity with which the transaction should be affiliated (e.g. a particular store)
Revenue	`Double`	Yes	The total revenue of a transaction, including tax and shipping
Tax	`Double`	Yes	The total tax for a transaction
Shipping	`Double`	Yes	The total cost of shipping for a transaction
Currency code	`String`	No	The local currency of a transaction. Defaults to the currency of the view (profile) in which the transactions are being viewed.

Items have the following fields:

Field Name	Type	Required	Description
Transaction ID	`String`	Yes	The transaction ID with which the item should be associated
Name	`String`	Yes	The name of the product
SKU	`String`	Yes	The SKU of a product
Category	`String`	No	A category to which the product belongs
Price	`Double`	Yes	The price of a product
Quantity	`Long`	Yes	The quantity of a product
Currency code	`String`	No	The local currency of a transaction. Defaults to the currency of the view (profile) in which the transactions are reported

Ecommerce data is used primary in the following standard reports:

Ecommerce Overview
Product Performance
Sales Performance
Transactions
Time to Purchase

Implementation

The TransactionBuilder and ItemBuilder is used to send transaction and item data to Google Analytics. Each ecommerce field is set using helper methods. For example:

// Build the transaction.
sendDataToTwoTrackers(new HitBuilders.TransactionBuilder()
    .setTransactionId(getOrderId())
    .setAffiliation(getStoreName())
    .setRevenue(getTotalOrder())
    .setTax(getTotalTax())
    .setShipping(getShippingCost())
    .setCurrencyCode("USD")
    .build());

// Build an item.
sendDataToTwoTrackers(new HitBuilders.ItemBuilder()
    .setTransactionId(getOrderId())
    .setName(getItemName(1))
    .setSku(getItemSku(1))
    .setCategory(getItemCategory(1))
    .setPrice(getItemPrice(getView(), 1))
    .setQuantity(getItemQuantity(getView(), 1))
    .setCurrencyCode("USD")
    .build());


// Sends the ecommerce data.
private void sendDataToTwoTrackers(Map<String, String> params) {
  AnalyticsSampleApp app = ((AnalyticsSampleApp) getActivity().getApplication());
  Tracker appTracker = app.getTracker(TrackerName.APP_TRACKER);
  Tracker ecommerceTracker = app.getTracker(TrackerName.ECOMMERCE_TRACKER);
  appTracker.send(params);
  ecommerceTracker.send(params);
}

See Advanced Configuration for details on the getTracker method.

}

Ecommerce currency fields support negative currency values, as may be necessary in the case of refunds or returns.

Specifying Currencies

By default, transaction values are assumed to be in the currency of the view (profile) in which they are reported.

To override the local currency of a transaction and any associated products, set the currency code field of the transaction and item hits with the new currency code. For the complete list of supported currencies and currency codes, see the Supported Currencies Reference.
