# Overview & Setup

Learn about User Interaction Events and how to integrate with tag managers.

## What are User Interaction Events?

User Interaction Events are a group of events available to all Komo customers by default without the need for a specifically tailored integration.

These events are automatically pushed to your configured tag manager, enabling seamless integration with other analytics and marketing tools.

## Card events in this documentation

- **[Common card events](/user-interaction-events/cards/common-events/)** — `card-viewed` and `card-shared`, shared by every card type.
- **[Events by card type](/user-interaction-events/cards/card-events/)** — every event each Komo card product can fire, with payload schemas (pick a product from the list).

## Supported Tag Managers

Google Tag Manager (GTM) and Adobe Launch Tag Manager are supported.
You can use these data layers to create custom triggers, send data to analytics, or automate marketing workflows.

### Google Tag Manager (GTM)

- Events are pushed to the `dataLayer` array.
- The `event` property is used to store the event name.
- The `eventData` property is used to store the event data.
- The `extensionData` property is used to store any [extension data](/user-interaction-events/extension-data).
- The `trackedData` property is used to store any [tracked data](/user-interaction-events/tracked-data).

### Adobe Launch Tag Manager

- Events are pushed to the `adobeDataLayer` array.
- The `event` property receives the event name.
- The `eventInfo` property receives the event data payload along with any [extension data](/user-interaction-events/extension-data) and [tracked data](/user-interaction-events/tracked-data).
