Integrating your business with Bloomreach Engagement is the first step in getting closer to your customers. Once integrated, you will immediately start getting data about your customers' behavior. If you need any assistance in deciding which API is the best for your business, please contact our integration specialist.

**Integration through Javascript** is recommended for a business based on web-browsing or for a business coded in other languages that still make use of Javascript.

# Basic integration

To integrate with Bloomreach Engagement using Javascript, you need to copy-paste the integration snippet into the header of your webpage. This step is an essential prerequisite for identifying your customers and tracking their actions. Read more about [the integration process here](🔗).

Checking if you initialized Bloomreach Engagement correctly

After copy-pasting the initialization code, open your business website in a new window and visit a few pages. Then open the Web integration window in the Bloomreach Engagement app. If you did everything correctly, it should say _Your tracking code is working_.

# Events

In Bloomreach Engagement, we distinguish between two types of events: system and custom ones. System events are automatically tracked across all projects. You can find their comprehensive list in the [**System events article**](🔗). Custom events are the ones specifically-tailored integration for each project and you can choose whether to incorporate them. You can find some of them with examples of how to track them below. However, if you are looking for a more extensive list go to the [**Custom events article**](🔗).

Deduplication of events

Every tracked or imported event is checked for possible deduplication. Read more [**here**](🔗).

## Purchase

The `purchase` event tracks the basic purchase transaction of your customers. It is crucial for analyzing the overall performance of your business, evaluating campaigns, calculating the lifetime value of your customers and much more.

**Overview of basic recommended attributes to track:**

## Purchase_item

`purchase_item` events are generated alongside every `purchase` event and are related to every item ordered within that purchase. For example, if a customer buys 1 unit of product A and 2 units of product B within one purchase, then a single `purchase` event and two `purchase_item` events are generated.

**Overview of basic recommended attributes to track:**

## Cart_update

Event `cart_update` is tracked whenever customers add or remove a product from the shopping cart. This event is mainly used in the [abandoned cart email campaign](🔗).

**Overview of basic recommended attributes to track:**

## View_item

Event `view_item` tracks every view of a product page, which allows you to know how many users are interested in each product.

**Overview of basic recommended attributes to track:**

## View_category

Event `view_category` tracks every view of a category page. This information is useful when determining what are the most visited categories.

**Overview of basic recommended attributes to track:**

## Checkout

Event `checkout` is used to track several steps of the purchase process, including the customer data acquisition, payment, shipping, and the transaction thank-you page. Tracking these steps is vital for analyzing where customers drop out.

**Overview of basic recommended attributes to track:**

## Registration

Event `registration` is tracked when a new user registers on the website. This event allows you to keep track of customer behavior or trigger automated marketing campaigns. In combination with the 'exponea.update' function, the attributes this event tracks will be attributed directly to the customer profile.

**Overview of basic recommended attributes to track:**

## Tracking list attributes

It is possible to track list attributes, that is equivalent to JS array. It is possible to use Bloomreach Engagement list filters with list attributes, which is not possible with objects (as shown above in cart_update).

# Customer identification

To know your customers better, you need to identify them with a unique identifier, such as e-mail or username.

## Automatic identification

Bloomreach Engagement automatically creates an anonymous customer when the method initialize() (e.g from [Javascript SDK](🔗)) is called for the first time on a device. These customers are identified by a generated cookie which means that subsequent sessions within a single device will be tracked to the same customer.

## Multi-device identification

Apart from the automatic cookie tracking, Bloomreach Engagement also allows clients to track a single customer across more platforms or devices. Therefore we can, for example, connect events that customers make in the Android and iOS version of your business.

## Hard IDs

We use the method identify(hard_id) to assign a hard ID (e.g. email address or username) to a user. When a customer with the given hard ID already exists, all customer profiles with the same ID will be merged. A new customer is created in Bloomreach Engagement every time a user is identified with a different hard ID. However, all previous events remain in the previous customer history.

## Implementation

We can use the identify() method in two ways:

• identify(hard_id);

  • identity field registered will be updated

• identify({identity: id});

  • We can save various hard IDs for a customer. However, customers are merged under every hard ID. Therefore if two customers with different `registered` are identified with the same hard ID identity field, event tracking will fail.

A good practice is to identify customers after every successful login/registration. More frequent identification may lead to problems with customer merging.

To read more about identifying customers, continue reading [the documentation for the `identify()` method](🔗).

### Multiple identities

If there are more identities (more than `registered` and `cookie`) in the project, you need to use a special identify call.

For example to identify with email_id you call:

If you are identifying a customer and you know all identities, you can also identify with:

🚧



If using caching on your web server, you need to make sure you do not insert the identify script into this part.

# Updating the customer’s profile

In addition to tracked events, every customer in Bloomreach Engagement has a set of attributes. Attributes can be used to contact the customer through a personalized campaign.

Read more [in our documentation about the `update()` method](🔗).

This guide should have provided you with all the basics needed to start tracking your first events and customers. We would love to help you get started as soon as possible, so if you have any questions, please contact our integration specialist.

# Advanced tracking

## Customizing default tracking

Default tracking behavior can be adjusted in the exponea.start(options) call:

You can also specify custom properties to be emitted with the `session_start` and `session_end` events.

📘



The _customer_ parameter can use any object with identifier same as _exponea.identify()_. When **string** is used, it will use identifier **registered** only.

## Action tracking

You can emit custom events when clicking links:

## Limitations

Characters . and $ are not allowed to be used in JSON keys. However, they can be used as values.

## Bot filtering

Bloomreach Engagement automatically filters out bot traffic which it can identify. This currently works by default and can’t be configured on project-level basis.

### Bloomreach Engagement filtering:

If customer/events is tracked with Bloomreach Engagement web tracking, and the message includes user-agent header with patterns from [this file](🔗), the message is automatically neglected. The message then isn’t stored within Bloomreach Engagement.

## Javascript SDK

All functionalities in a detail are described in a [Javascript SDK](🔗).
