# Subscription

To track an event using the subscription package, you can use the corresponding method on the tracker instance. For example:

## Example

{% tabs %}
{% tab title="Android" %}

```kotlin
val properties = SubscriptionSubscriptionCreatedProperties(
    endDate = endDate
)
bird.tracker.subscription.subscriptionCreated(properties)
```

{% endtab %}

{% tab title="Swift" %}

```swift
let properties = SubscriptionSubscriptionCreatedProperties(
    endDate: endDate
)
bird.tracker.subscription.subscriptionCreated(properties)
```

{% endtab %}

{% tab title="Web" %}

```javascript
const properties: SubscriptionSubscriptionCreatedProperties = {
    end_date: end_date
};
Bird.tracker.subscription.subscriptionCreated(properties, event_opts);
```

{% endtab %}
{% endtabs %}
