# Task

## Canceled

`com.twilio.taskrouter.task.canceled`

> \[!NOTE]
>
> The `worker_time_in_previous_activity` field began reporting in seconds starting May 21, 2021. Version 2 of the TaskRouter schema added a new `worker_time_in_previous_activity_ms` field that was not exposed through Event Streams previously. If you want to measure this field in milliseconds, you must use schema version 2.

Task Canceled events are compatible with Webhook and Kinesis sinks. To learn more, you can get started with the [Webhook](/docs/events/webhook-quickstart) or [Kinesis](/docs/events/eventstreams-quickstart) quickstarts and refer to the [product documentation](/docs/taskrouter/api/event).

## Deleted

`com.twilio.taskrouter.task.deleted`

> \[!NOTE]
>
> The `worker_time_in_previous_activity` field began reporting in seconds starting May 21, 2021. Version 2 of the TaskRouter schema added a new `worker_time_in_previous_activity_ms` field that was not exposed through Event Streams previously. If you want to measure this field in milliseconds, you must use schema version 2.

Task Deleted events are compatible with Webhook and Kinesis sinks. To learn more, you can get started with the [Webhook](/docs/events/webhook-quickstart) or [Kinesis](/docs/events/eventstreams-quickstart) quickstarts and refer to the [product documentation](/docs/taskrouter/api/event).

Version 2 of the TaskRouter schema added a new `worker_time_in_previous_activity_ms` field that was not exposed through Event Streams previously. If you want to measure this field in milliseconds, you must use schema version 2.

## Wrapup

`com.twilio.taskrouter.task.wrapup`

> \[!NOTE]
>
> The `worker_time_in_previous_activity` field began reporting in seconds starting May 21, 2021. Version 2 of the TaskRouter schema added a new `worker_time_in_previous_activity_ms` field that was not exposed through Event Streams previously. If you want to measure this field in milliseconds, you must use schema version 2.

Task Wrapup events are compatible with Webhook and Kinesis sinks. To learn more, you can get started with the [Webhook](/docs/events/webhook-quickstart) or [Kinesis](/docs/events/eventstreams-quickstart) quickstarts and refer to the [product documentation](/docs/taskrouter/api/event).
