#### Data store actions

Using the `@woocommerce/data` package, the following selectors and actions are available to interact with the task lists under the onboarding store.

```js
import { ONBOARDING_STORE_NAME } from '@woocommerce/data';
import { useSelect } from '@wordpress/data';

const { snoozeTask } = useDispatch( ONBOARDING_STORE_NAME );
const { taskLists } = useSelect( ( select ) => {
  const { getTaskLists } = select( ONBOARDING_STORE_NAME );

  return {
    taskLists: getTaskLists(),
  };
} );
```


* `getTaskLists` - (select) Resolve any registered task lists with their nested tasks
* `hideTaskList( id )` - (dispatch) Hide a task list
* `actionTask( id )` - (dispatch) Mark a task as actioned
* `snoozeTask( id )` - (dispatch) Snooze a task
* `dismissTask( id )` - (dispatch) Dismiss a task
* `optimisticallyCompleteTask( id )` - (dispatch) Optimistically mark a task as complete


### SlotFills

The task UI can be supplemented by registering plugins that fill the provided task slots.

#### Task content

A task list fill is required if no `action_url` is provided for the task.  This is the content shown after a task list item has been clicked.

```js
import { WooOnboardingTask } from '@woocommerce/onboarding';

registerPlugin( 'my-task-plugin', {
	scope: 'woocommerce-tasks',
	render: () => (
    <WooOnboardingTask id="my-task">
      { ( { onComplete, query } ) => (
        <MyTask onComplete={ onComplete } />
      ) }
    </WooOnboardingTask>
	),
} );
```
#### Task list item

The items shown in the list can be customized beyond the default task list item.  This can allow for custom appearance or specific `onClick` behavior for your task.

```js
import { WooOnboardingTaskListItem } from '@woocommerce/onboarding';

registerPlugin( 'my-task-list-item-plugin', {
	scope: 'woocommerce-tasks',
	render: () => (
    <WooOnboardingTaskListItem id="appearance">
      { ( { defaultTaskItem, onComplete } ) => (
        <MyTaskListItem onComplete={ onComplete } />
      ) }
    </WooOnboardingTaskListItem>
	),
} );
```

### Endpoints

The following REST endpoints are available to interact with tasks.  For ease of use, we recommend using the data store actions above to interact with these endpoints.
