# requestAuthorization(handler:)

Requests authorization to receive notifications about fall detection events.

```
func requestAuthorization(handler: @escaping (CMAuthorizationStatus) -> Void)
```

## Parameters

`handler`

A block that is called by the system after the user accepts or declines the authorization request.

    The system passes the following parameter:

- `status`: The authorization status chosen by the user.

## Discussion

As soon as the user authorizes fall detection, the system calls the delegate’s [`fallDetectionManager(_:didDetect:completionHandler:)`](/documentation/CoreMotion/CMFallDetectionDelegate/fallDetectionManager(_:didDetect:completionHandler:)) method and passes the latest fall detection event.
