# webView(_:requestMediaCapturePermissionFor:initiatedByFrame:type:decisionHandler:)

Determines whether a web resource, which the security origin object describes, can access to the device’s microphone audio and camera video.

## Declaration

```swift
optional func webView(_ webView: WKWebView, requestMediaCapturePermissionFor origin: WKSecurityOrigin, initiatedByFrame frame: WKFrameInfo, type: WKMediaCaptureType, decisionHandler: @escaping @MainActor @Sendable (WKPermissionDecision) -> Void)
```

```swift
optional func webView(_ webView: WKWebView, decideMediaCapturePermissionsFor origin: WKSecurityOrigin, initiatedBy frame: WKFrameInfo, type: WKMediaCaptureType) async -> WKPermissionDecision
```

## Parameters

- `webView`: The web view requesting permission for microphone audio and camera video.
- `origin`: An object that identifies the host name, protocol, and port number for a web resource.
- `frame`: The frame that initiates the request in the web view.
- `type`: An enumeration case representing a type of media capture device, like a microphone or camera.
- `decisionHandler`: A closure that you call from your delegate method. Pass the permission decision you determine to the closure.

## Discussion
