# endAction(_:)

Tells the host application that the plug-in is done accessing parameters.

## Declaration

```swift
func endAction(_ sender: Any!)
```

## Parameters

- `sender`: The view class that implements this protocol. Typically passed as self.

## Mentioned in

Adding parameters to plug-ins

## Discussion

Discussion It is important to note that OSC plug-ins (implementing FxOnScreenControl_v4) should not use startAction(_:) and endAction(_:), as the host is already aware that parameters are likely to change.
