This guide is for developers who want to set up data tracking using the default data layer events supported by the Frosmo Platform. If your site has or is getting a basic feature setup from Frosmo, see the appropriate site preparation guide instead. Basic feature setups rely on their own dedicated data layer events.


To use the data layer on a site, the data layer module must be enabled for the site.

For an introduction to product tracking in the Frosmo Platform, see Data tracking solutions#Product tracking.

Tracking products with the data layer means triggering a product view event whenever a visitor navigates to a product page or otherwise views a product on a site. The data you pass in the product view event is the product data for the viewed product.

On iGaming sites, a product view is called "game open" and a product view event is therefore "game open event".

You can trigger product view events from:

Page code is the recommended solution. If you cannot use the data layer in your page code, use shared code.

Figure: Tracking products by triggering a product view event from a page (click to enlarge)

When you trigger a product view event, how the Frosmo Platform handles the event and the products defined in the event data depends on the event's mode setting:

To verify that the tracked product data is correctly stored in the Frosmo back end, view the product data in the Frosmo Control Panel.

Triggering product view events

To trigger a product view event, call the dataLayer.push() function with the following object:

dataLayer.push({
    frosmo: {
        view: {
            products: [{
                /* Standard attributes */
                id: '<product_id>',
                availability: '<product_availability>',
                brand: '<product_brand>',
                image: '<product_image_url>',
                name: '<product_name>',
                originalPrice: <product_original_price>,
                parentId: '<parent_product_id>',
                price: <product_current_price>,
                type: '<product_type>',
                url: '<product_page_url>',

                /* Custom attributes */
                <key>: <value>,
                ...
            }],
            /* Optional */
            mode: 'set|setView|view'
        }
    }
});

The frosmo.view object contains the event data.

view object

The view object contains the data of a single product view event.

Table: view object properties

PropertyDescriptionTypeRole
products

List of viewed products.

Define each product as a product object.

You must define at least one product. If the list is empty, the platform ignores the event.

Array of product objectsRequired
mode

Set how the Frosmo Platform treats the event and event data.

The possible values are:

  • set: Save the product data, but do not register views for the products. The event has no effect on features that rely on product views. For example, the event does not impact affinity tracking or recommendations.
  • setView: Save the product data, and register a view for each product.
  • view: Register a view for each product, but do not save the product data.

The default value is setView.

If the site's product data comes exclusively from a product data feed, always set this to view.


StringOptional

Product object

The product object contains the data (attributes) for a single product. You can define standard attributes and custom attributes for a product.

The Frosmo Platform automatically trims string values by removing opening and ending white spaces. Empty string values are valid for all string attributes except id.

Standard attributes

To get the most out of the Frosmo Platform, include as many optional standard attributes in your product data as possible.

Table: Product object properties (standard attributes)

PropertyDescriptionTypeRole
id

Product ID.

The value must be a non-empty string.


String (256)Required
availability

Product availability in the web store.

The possible values are:

  • in stock
  • out of stock
  • preorder

If you provide a value other than one of those listed, the data layer push fails, and no product data is updated.

StringOptional
availableOn

Date and time when the product becomes or has become available to visitors, for example, for purchase.

This property typically indicates how new the product is to the site.

Datetime string (ISO 8601)Optional
brandBrand name for the product, or the company that produces the product.String (2048)Optional
categories

Categories to which the product belongs. This can also be keywords, tags, types, or any other set of classifiers used on the site.

You can define a hierarchy of parent and child categories as a breadcrumb using / as the separator. For example:

  • Electronics/Televisions/OLED
  • Electronics/Televisions/OLED/4K
  • Electronics/Televisions/Smart

The maximum stringified length for the array is 2048 characters.

If you only need to define a single category for a product, use the type attribute instead.

Use either categories or type for all products on the site.


Array of strings (2048)Optional
image

Product image URL.

Even if you do not have a value for this property, it is recommended that you nonetheless pass an empty string.


String (2048)Optional
name

Product name.

Even if you do not have a value for this property, it is recommended that you nonetheless pass an empty string.


String (256)Optional
originalPrice

Original unit price for the product.

Use this property for the original starting price before any discounts.

NumberOptional
parentId

ID of the parent product, if the current product is a product variant.

If your site has a product feed that provides the baseline product data to the Frosmo Platform, you can omit this parameter or set it to null. The feed data contains the necessary information about parents and variants, so the database entry for the current product already includes the parent ID, assuming the product is a variant.

If your site does not have a product data feed, and if you know the ID of the parent product, use this property to define the current product as a variant of the parent.

If the parent product does not exist in the database, the platform ignores the product view event.


Do not define this property if the product is itself a parent product. Parent products cannot have parents, and product variants cannot have variants.


If you define a parent product ID that differs from the one already stored for this product in the database, the new ID overwrites the existing ID.

For recommendation generation purposes, the platform calculates product variant statistics (views, conversions, transactions) for the parent product. Recommendations only return parent products (as they contain the combined statistics for a product).

String (256)Optional
price

Current unit price for the product, such as a discount price.

Even if you do not have a value for this property, it is recommended that you nonetheless pass an empty string.


NumberOptional
type

Product category. This can also be a keyword, tag, type, or any other form of classification used on the site.

Define a hierarchy of parent and child categories as a breadcrumb using / as the separator. For example: Electronics/Televisions/OLED

Even if you do not have a value for this property, it is recommended that you nonetheless pass an empty string. This property can be used in segmentation rules and therefore needs to have a value.


If you need to define multiple categories for a product, use the categories attribute instead, and set this attribute to an empty string.

Use either categories or type for all products on the site.


String (256)Optional
url

Product page URL.

Even if you do not have a value for this property, it is recommended that you nonetheless pass an empty string.


String (2048)Optional

Custom attributes

If the standard attributes are not sufficient to track your product data, define the necessary custom attributes to complement the standard ones. You can freely define as many custom attributes as you need for your products.

A custom attribute must meet the following requirements:

If the custom attribute is an object, the object properties can be anything you want them to be. The Frosmo Platform does not validate the properties against any data model or schema.

You cannot filter recommendation data by object properties. If you want to use a custom attribute for filtering recommendations, use one of the other supported data types.

Testing product tracking

For instructions on how to test that products are correctly tracked on a site, see Testing data tracking#Product tracking.

Triggering product view events (deprecated method)

Do not use this method if you are preparing a site for integration with the Frosmo Platform.

This section documents the legacy method for tracking products with the data layer. This method is officially deprecated, and the documentation is no longer maintained. If your site still uses this method, it is recommended that you migrate to the current solution. Contact Frosmo support to discuss the migration.

To trigger a product view event, call the dataLayer.push() function with a product object containing the product data:

dataLayer.push({
    frosmoProductId: 'string',
    /* Optional */
    frosmoProductCategory: 'string',
    frosmoProductData: {},
    frosmoProductDiscountPrice: 0,
    frosmoProductImage: 'string',
    frosmoProductName: 'string',
    frosmoProductPrice: 0,
    frosmoProductPromotionLabel: 'string',
    frosmoProductUrl: 'string'
    /* ... */
});

Product object (deprecated)

The product object contains the data (attributes) for a single product.

Table: Product object properties

PropertyDescriptionTypeRole
frosmoProductId

Product ID.

The Frosmo Platform uses the product ID to uniquely identify the product.

String (256)Required
frosmoProductArea

Geographical region, typically a part of a country, that applies to the product in some way.

For example, if the product is a hotel room, this property can provide the name of the in-country region in which the hotel is located:

  • frosmoProductCountry: Greece
  • frosmoProductArea: Rhodes
  • frosmoProductCity: Lindos
String (32)Optional
frosmoProductCampaignSales or other campaign with which the product is associated.String (32)Optional
frosmoProductCategories

Additional product categories to which the product belongs.

For more information about the object type, see the instructions below this table.

One of:

  • Array of strings
  • Stringified array of strings (1024)
  • Object
  • Stringified object (1024)
Optional
frosmoProductCategory

Product category or type.

Even if you do not have a value for this property, it is recommended that you nonetheless pass an empty string. This property can be used in segmentation rules and therefore needs to have some value.


String (256)Optional
frosmoProductCity

City or town that applies to the product in some way.

For example, if the product is a hotel room, this property provides the name of the city or town in which the hotel is located:

  • frosmoProductCountry: Greece
  • frosmoProductArea: Rhodes
  • frosmoProductCity: Lindos
String (32)Optional
frosmoProductColors

Color options for the product.

For more information about the object type, see the instructions below this table.

One of:

  • Object
  • Stringified object (1024)
Optional
frosmoProductCompanyCompany that offers the product.String (32)Optional
frosmoProductConversion

If you want to merely send the product data to the Frosmo back end without triggering a product view event, set this property to 1. In this case, the Frosmo Platform does not increment the view count for the product, but instead just stores the product data.

The default value is 0, which means that the Frosmo Platform also registers the product data push as a product view.

Despite the name, this property does not trigger a conversion event for the product, regardless of the property value. If you want to register a conversion for the product, trigger a conversion event or transaction event instead.


NumberOptional
frosmoProductCountry

Country that applies to the product in some way.

For example, if the product is a hotel room, this property provides the name of the country in which the hotel is located:

  • frosmoProductCountry: Greece
  • frosmoProductArea: Rhodes
  • frosmoProductCity: Lindos
String (32)Optional
frosmoProductCustomImages

URLs of additional product images.

For more information about the object type, see the instructions below this table.

One of:

  • Object
  • Stringified object (2048)
Optional
frosmoProductData

Any piece of product data that does not logically belong to the other product properties but that you want to push with the product data. Use this property to send your own custom product attributes along with the product data.

For more information about the object type, see the instructions below this table.

One of:

  • Object
  • Stringified object (2048)
Optional
frosmoProductDescriptionProduct description.String (512)Optional

Promotion-related label, such as "Weekend Sale" or "80% off!".

This property is intended for promotion-related label strings. Do not use this property for stringified objects. If you need to store extra product data beyond the standard product data properties listed here, use the frosmoProductData property.

frosmoProductVenue

String (64)Optional


Follow these rules for product object properties whose type is object:

  • The value can be either a JavaScript object or a JSON-stringified object. In the latter case, the maximum length of the string is either 1024 or 2048 characters, depending on the property (see above).
  • The properties of the object can be anything you want them to be. The Frosmo Platform does not validate the properties against any data model or schema.

If you assign a JavaScript object to a product object property, the Frosmo Platform stringifies the value. If you assign a stringified object to a property, the platform stores the value as-is.
