# beginRequest(with:)

Tells the extension to prepare for a host app’s request.

## Declaration

```swift
func beginRequest(with context: CXCallDirectoryExtensionContext)
```

## Parameters

- `context`: A CXCallDirectoryExtensionContext object that represents the context in which the host app makes the request.

## Mentioned in

Identifying and blocking calls

## Discussion

Discussion An extension prepares for a host app’s request by getting the context passed in this method and requesting related data items, if appropriate. This method is received after the extension is initialized, but before the principal object is asked to do anything with the context.
