Commerce Events

Collecting accurate “commerce” data is vital if users can purchase any physical or virtual goods in your app. Some important use-cases powered by commerce data include:

  • Identifying users who have a high lifetime value
  • Tracking the success of your advertising campaigns
  • Driving predictive analysis, such as recommendations

The mParticle SDK provides dedicated commerce APIs to collect commerce data in a form that can be usefully passed on to your integrations. mParticle’s commerce data structure closely follows the standard created by the Google Analytics Enhanced Ecommerce API.

Some mParticle partners track commerce data at a granular level, others are only interested in the currency amount of a transaction, while others provide no commerce support at all. mParticle’s commerce schema is designed to be flexible to deterministically map to all integration types.

Tracking Basic Purchases

mParticle’s full commerce feature-set allows you to track a full purchase flow, from promotions, to product impressions, through multiple checkout steps. However, for some use cases it is sufficient to track only the purchase itself.

Basic purchase tracking is a three-step process:

  1. Create the product or products

    • This step creates a representation of each product being purchased
    • At a minimum, products must have a name, an SKU, and a price
    • If multiple units of a product are being purchased, a quantity can be set. If not set, quantity defaults to 1.
    • Like users and events, products can also include custom attributes defined as key/value pairs within an object.
  2. Summarize the transaction details include:

    • (required) Transaction ID- each transaction must have a unique ID
    • Revenue - the total amount of the transaction
    • Shipping - the amount of revenue used for shipping
    • Tax - the amount of revenue collected for taxation.
  3. Log the purchase event - the purchase event includes the products and transaction summary created above, as well as an optional object containing custom attributes and an optional object containing custom flags.
// 1. Create the product

// Optional custom attributes for products can be defined as key/value pairs within an object
var customProductAttributes = {
    'ocean-view': true,
    'balcony': false

var product1 = mParticle.eCommerce.createProduct(
    'Double Room - Econ Rate',  // Name
    'econ-1',                   // SKU
    100.00,                     // Price
    4,                          // Quantity
    'variant',                  // Variant
    'room',                     // Category
    'lodge-o-rama',             // Brand
    'banner',                   // Position
    null,                       // Coupon code
    customProductAttributes     // The custom attributes defined in a separate variable above

var product2 = mParticle.eCommerce.createProduct(
    'Double Room - Econ Rate',

// 2. Summarize the transaction
var transactionAttributes = {
    Id: 'foo-transaction-id',
    Revenue: 430.00,
    Tax: 30

// 3. Log the purchase event

// Optional custom attributes for a product action can be defined as key/value pairs witin an object
var customAttributes = {
    'sale': true

// Optional custom flags can be defined as key/value pairs within an object
var customFlags = {
    'Google.Category': 'travel'

    [product1, product2],

Product Events

Product-based commerce events measure all interactions with a product that can lead up to a purchase. Product events can include:

  • tapping or viewing products
  • adding or removing products from a cart or wishlist
  • advancing through a multi-step checkout process
  • purchases
  • refunds

The first step in any product-based event is to create the products. See basic purchase tracking for help creating products.

Once you have your products, you can log events via the mParticle.eCommerce.logProductAction() method, shown below.

Additional Commerce event types

Our Commerce API allows you to highly customize your Commerce flow. All product events take a ProductAction (which identifies the action being captured), a single product (or an array of products), custom attributes, custom flags, and transaction attributes. Purchases, refunds, and checkout events require a transaction attributes object to provide fuller detail of the event.

// With the product created above, you can perform any of the above product actions. Some examples include:

// Adding/Removing items to/from your cart
mParticle.eCommerce.logProductAction(mParticle.ProductActionType.AddToCart, product, customAttributes);
mParticle.eCommerce.logProductAction(mParticle.ProductActionType.RemoveFromCart, product, customAttributes);

// Checkout (continuation of transactionAttributes above)
transactionAttributes.Step = 2;
transactionAttributes.Option = 'Visa';

    [product1, product2],

The complete list of possible product actions includes:

  • AddToCart
  • RemoveFromCart
  • Checkout
  • CheckoutOption
  • Click
  • ViewDetail
  • Purchase
  • Refund
  • AddToWishlist
  • RemoveFromWishlist
  • Unknown

You can choose to track all of these actions, or any combination that suits your needs.

Use the Cart API

Due to the varied methods of implementing and maintaining a cart on client applications, we have found that this could possibly lead to syncing issues and thus we’ve decided to deprecate the mParticle cart.

Promotion Events

“Promotion” events are used to represent internal offers - such as discounts - that might be displayed in a banner advertisement. Promotion events are created by specifying a promotion action string, and one or more promotions. When constructing a promotion it’s recommended to specify at least an ID or a name.

var promotion = mParticle.eCommerce.createPromotion(
    'my_promo_1', // Promotion ID
    'sale_banner_1', // Promotion Creative
    'App-wide 50% off sale', // Promotion Name
mParticle.eCommerce.logPromotion(mParticle.PromotionType.PromotionClick, promotion);

Impression Events

“Impression” events are used to represent any time one or more products are displayed on the screen. Optionally, you can specify a name for the location or list in which the products appeared.

var impression = mParticle.eCommerce.createImpression('Suggested Products List', product);

Forwarding Commerce Data to Partners

mParticle commerce events can capture a transaction including multiple products in a single event. Many of our partners take a different approach and only capture purchases at the level of a product. At the simplest end of the spectrum, some partners are only interested in logging the increase in a user’s lifetime value and capture no product details at all. For this reason, it’s important that both your individual products and the transaction summary are complete and correct.

When instrumenting your app with mParticle, you don’t need to worry about the requirements of individual partners. Capture your purchase events in as much detail as you have and mParticle takes care of transforming the data for each partner. Most commonly, this involves “expanding” a commerce Event. This means automatically creating a new separate event for each product in the original event and copying the shared attributes to each new event.

Currency Code

Some partners, like GA4, require a currency code to be set in order to ingest commerce data and trigger revenue. Use the below snippet to set the currency code on the mParticle eCommerce object:
