### Event Main event abstract class for inheriting classes.
This is an abstract class and it is not meant to be instantiated directly. You should use concrete subclasses instead.
**Declared In:** lib/model/tracker/event.dart **Declaration:** 
abstract class Event
**Properties:** | Property | Type | Optional | Description | | --- | --- | --- | --- | | **type** | String | no | Event type | | **label** | String | no | Can't be empty. This value isn't saved in persistent storage and can't be used in Decision or Automation Hubs. It isn't shown on a Profile card. | | **action** | String | no | Event action | | **parameters** | bool | no | Event parameters | --- --- ### CustomEvent
DO NOT send `transaction.charge` events as custom events.
Transactions must be tracked with these endpoints: - [`/v4/transactions`](https://developers.synerise.com/DataManagement/DataManagement.html#operation/CreateATransaction) (single transaction) - [`/v4/transactions/batch`](https://developers.synerise.com/DataManagement/DataManagement.html#operation/BatchAddOrUpdateTransactions) (multiple transactions)
