## Format

The format for sending [custom events](docId\:w0DeSMy7YSyAm7PnwzGqq) in the ODP Web SDK is as follows:

```javascript
zaius.event("your_event_type_here", { 
    action: "your_event_action_here",
    example_custom_field: "example_value"
});
```

## Custom event examples

The following examples show Web SDK custom events and how those custom events display on the customer profile in ODP.

The value in the `campaign` event type displays on the customer profile. For example, if `campaign` is set to `Opticon Newsletter`, then Opticon Newsletter displays on the customer profile in ODP.

### Forms

```javascript
zaius.event('web_form', {
  action: 'impression', 
  form_name: 'Opticon Newsletter', 
  campaign: 'Opticon Newsletter' 
});

zaius.event('web_form', {
  action: 'submission', 
  form_name: 'Opticon Newsletter', 
  campaign: 'Opticon Newsletter' 
});
