# resumeMonitoring(placeholderURL:)

Informs the system that it needs to resume monitoring the download.

```
@objc(resumeMonitoring:completionHandler:) func resumeMonitoring(placeholderURL: URL) async throws
```

## Parameters

`placeholderURL`

The placeholder location your networking extension previously received when it called [`beginMonitoring()`](/documentation/BrowserEngineKit/BEDownloadMonitor-9bwls/beginMonitoring()).

## Discussion

Call this method when your browser resumes the download after an interruption, for example, someone cancels the download, or your networking extension encounters a network error.
