# setPermissionStatus(_:for:expirationDate:)

Sets the status of a permission with a specific expiration date.

```
func setPermissionStatus(_ status: WKWebExtensionContext.PermissionStatus, for permission: WKWebExtension.Permission, expirationDate: Date?)
```

## Parameters

`status`

The new permission status to set for the given permission.

`permission`

The permission for which to set the status.

`expirationDate`

The expiration date for the new permission status, or \c nil for distant future.

## Discussion

This method will update [`grantedPermissions`](/documentation/WebKit/WKWebExtensionContext/grantedPermissions) and [`deniedPermissions`](/documentation/WebKit/WKWebExtensionContext/deniedPermissions). Use this method for changing a single permission’s status.

Passing a `nil` expiration date will be treated as a distant future date. Only [`WKWebExtensionContext.PermissionStatus.deniedExplicitly`](/documentation/WebKit/WKWebExtensionContext/PermissionStatus/deniedExplicitly), [`WKWebExtensionContext.PermissionStatus.unknown`](/documentation/WebKit/WKWebExtensionContext/PermissionStatus/unknown), and [`WKWebExtensionContext.PermissionStatus.grantedExplicitly`](/documentation/WebKit/WKWebExtensionContext/PermissionStatus/grantedExplicitly) states are allowed to be set using this method.
