# Setup custom events
### Overview
Custom event tracking enables you to monitor and analyze user interactions, business metrics, and application behavior by capturing specific events throughout your system. This feature provides the flexibility to track any custom action or milestone that matters to your business.
How it works
### Prerequisites
Pulse must be installed on your website using the custom pixel code snippet. If you haven't installed it yet, please check the [installation guide](https://booleanmaths.gitbook.io/booleandocs/getting-started/install-pulse-website) first.
### Implementation by Platform
#### Shopify Websites
**No additional setup required** - Our Shopify plugin automatically manages all required events for Shopify stores.
#### Non-Shopify Websites
Custom events implementation involves two layers:
1. **Data Layer**: Collect and prepare business data for tracking and analysis
2. **Event Endpoint**: Send the prepared data to BooleanMaths
Example: Form Tracking Implementation
Let's implement form tracking using the `FormFilled` event:
| Parameter | Type | Description | Example |
| ----------------- | ------ | --------------------------- | ------------------------------------------------------------ |
| form\_name\* | string | Name of target form | Peter Parker |
| form\_data\* | Json | Form details filled by user | { "email": "", "name" : "Peter Parker", } |
| conversion\_value | float | Conversion value | 10 |
Note: '\*' fields are required to identify user. All other fields are optional
FormFilled event accepts above data values. For data layer we need to write some custom code so that we can connect data with this event.\
