Tealium Events Extension

The Tealium Events extension defines standard conditions for the most commonly tracked events.

This extension adds the tealium_event variable to your data layer, where it can help simplify tag mappings, load rules, or other conditions. It can also be passed to Tealium EvenStream via the Tealium Collect tag.

How it works

This extension introduces standardized event names into your solution, along with a new variable in your data layer called tealium_event. It covers the standard e-commerce customer journey and includes familiar events such as Add to Cart, Product Detail Page View, and Purchase Complete. Since these events are typically represented in the data layer using page_type and event_name, this extension acts as a translation between your current page/event tracking conditions and the new standardized Tealium event names.

Each event may be assigned to a custom condition that matches your data layer implementation. When an event condition evaluates to true, tealium_event is set to the pre-defined event value. For example, when the condition for Add to Cart evaluates to true, tealium_event is set to cart_add. See the Standard Events section below.

Using the extension

Before you begin, familiarize yourself with how extensions work.

Once the extension is added, you may customize event conditions according to your implementation needs. The list of events are not changeable, but the event conditions are changeable. To customize an event condition:

  1. Click an event, and then click Edit.
  2. Adjust the condition logic as needed.
  3. Click Apply.

Removing conditions

To prevent an event from being set, remove the condition and click Apply. This changes the event from being Set to Not Set and is no longer be evaluated in your configuration.

In this example, the condition for the Email Signup event has been removed, resulting in the event to be Not Set.

Standard events

Below is a table of standard events and default conditions in the extension. Events are listed in alphabetical order and are evaluated sequentially. The default conditions match our standard data layer recommendations, but they are customizable to match your exact implementation.

Event tealium_event Default Condition
Add to Cart cart_add event_name="cart_add"
Category Page View category_view page_type="category"
Checkout checkout page_type="checkout"
Email Signup email_signup event_name="email_signup"
Empty cart cart_empty event_name="cart_empty"
Page View page_view page_type="generic"
Product Detail Page View product_view page_type="product"
Purchase Complete purchase page_type="purchase"
Remove from Cart cart_remove event_name="cart_remove"
Search Page View search page_type="search"
Shopping Cart View cart_view page_type="cart"
Social Share social_share event_name="social_share"
User Log in user_login event_name="user_login"
User Log out user_logout event_name="user_logout"
User Register user_register event_name="user_register"

The tealium_event value is always set for the condition that last evaluated to true. If more than one event condition evaluates to true, the event lower in the list is set.

Custom events

The Tealium Events extension provides a list of predefined events. A custom event uses a value defined by you and assigned to the variable tealium_event. Define these custom events directly in your data layer or by using the Set Data Values extension.

Position custom events defined in an extension after the Tealium Events extension.

To define a custom event using an extension:

  1. Add a Set Data Values extension.
  2. Drag the new extension below the existing Tealium Events extension to ensure it runs after it.
  3. In the Set drop-down list select tealium_event .
  4. In the text field type the name of your custom event.
  5. Add a condition to identify your custom event.

Example of custom event using the Set Data Values extension:

The goal of the extension is to standardize the event name value into the tealium_event variable used in your configuration. Here are some uses for this variable:

Event mappings in tags

Simplify tag configurations that support page and event mappings by using a single variable, tealium_event, to configure these events.

Load rules

Load rules use tealium_event to simplify their conditions.

Customer Data Hub

If you have the Tealium Collect tag all the variables in your data layer are passed along to Tealium EventStream, including tealium_event. This variable is made available as an imported event attribute to be used in enrichments, rules, and feeds.
