# Google Tag Manager
Track user activities with Google Tag Manager using Rezolve AI's provided GTM templates for streamlined front-end tracking implementation.
Use the provided Google Tag Manager (GTM) templates to track [user activities](/product-discovery/tracking-and-sending-events/activities.md).
## Prerequisites
* Configured GTM container
* Data layer containing the [information to be tracked](/product-discovery/tracking-and-sending-events/setup-guide/prerequisites.md#ensure-data-provision) (if possible)
* Tracker key
{% hint style="info" %}
To obtain your tracker key(s), reach out to your Customer Support Manager.
{% endhint %}
## GTM Templates
We provide the following two templates for use:
* [XO Activities Tracking](https://tagmanager.google.com/gallery/#/owners/Attraqt/templates/xo-activities-gtm): Use for sending one activity event for each user action
* [XO Multi-Activities Tracking](https://tagmanager.google.com/gallery/#/owners/Attraqt/templates/xo-multiactivities-gtm): Use for sending mutiple activity events for a single user action
Access these templates by clicking the links above. Alternativey, in the [***Community Template Gallery***](https://tagmanager.google.com/gallery/#/), search for "**XO Activities Tracking"** or "**XO Multi-Activities Tracking"**.
{% hint style="info" %}
The XO templates are used for both FHR and XO.
{% endhint %}
### XO Activities Tracking
The XO Activities Tracking template is the main template. Use this template to send one activity event for each user action:
1. Add the template to your workspace.
2. Using the **New** button in the **Tag** section, add a new tag.
3. Select the **XO Activities Tracking** template.\
-> A configuration window opens.
4. Add your **tracker key** in the assigned field.
5. Choose an **action**.\
Each field corresponds to a **variable**, which means that you can configure **multiple actions** on the tag if your variable is dynamic. Otherwise, you should have an individual tag for each tracking action.
6. Add one or more **targets**.\
A **target** is a key-value pair which corresponds to the **target** property of the [**activity** **object**](/product-discovery/tracking-and-sending-events/activities/activity-object.md).
7. Add one or more **identities**.\
An **identity** is a key-value pair. The key corresponds to the name of the **identity** (such as: "**sessionId"**) and the value to the **ID** of that identity for the visitor (the actual **session ID**).
8. Optional: Add any additional information about the user, such as **traits**, or **segments,** in the **User information** section. These fields correspond to the different parts of the [**user object**](/product-discovery/tracking-and-sending-events/identities/user-object.md).
9. Optional: Add any additional details around the **activity**, such as **metadata**, in the **Activity information** section.
{% hint style="warning" %}
The section **Advanced Settings** is not part of the XO tag configuration.
{% endhint %}
#### Example
A basic tracking configuration for events that relate to a single product should look like this:
### XO Multi-Activity Tracking
Use this template to send multiple activity events for a single user action, such as when a user purchases multiple items in their basket:
1. Add the template to your workspace.
2. Use the **New** button in the **Tag** section, add a new tag.
3. Select the **XO Multi-Activities Tracking** template.
{% hint style="warning" %}
For the most part, you can use this template in the same way as the [**XO Activities Tracking** template](#xo-activities-tracking). The key difference in the requirement of a [**variable**](https://support.google.com/tagmanager/answer/7683056?hl=en) containing all the necessary product information.
{% endhint %}
4. Set up your variable in the "Target list" section.
Your **variable** should be an array of objects like in the following example:
```json
"buyedProducts": [
{id: "product1", "price": 100, quantity: 1},
{id: "product2", "price": 50, quantity: 2}
]
```
5. To set product-specific values for an event, add rows to the **Attributes** section.\
Each row corresponds to a different value in your **variable**, and allows you to define what it will be mapped to in the activity object.\
In the following example, we will map the **ID**, **price** and **quantity** from our **variable** (the input object) to the `target.product` , `metadata.price` and `metadata.quantity` fields in the resulting activity object.
{% hint style="danger" %}
Each tracker key can only be used with a single currency.
{% endhint %}
6. To set information that is specific to this group of events, and not each product (eg: orderId or currency) you can add them in the **common** section.
