# permissionStatus(for:in:)

Checks the specified match pattern against the currently denied, granted, and requested permission match patterns.

```
func permissionStatus(for pattern: WKWebExtension.MatchPattern, in tab: (any WKWebExtensionTab)?) -> WKWebExtensionContext.PermissionStatus
```

## Parameters

`pattern`

The pattern for which to return the status.

`tab`

The tab in which to return the permission status, or `nil` if the tab is not known or the global status is desired.

## Discussion

Match patterns can be granted on a per-tab basis. When the tab is known, access checks should always use this method.
