# Method name: getDownloadUrl(fileUrl: string, expirationTime: number, downloadedFileName: string, expiredTokenRedirectUrl: string)

# Method package: wixMediaBackend

# Method menu location: wixMediaBackend --> MediaManager --> getDownloadUrl

# Method Link: https://dev.wix.com/docs/velo/apis/wix-media-backend/media-manager/get-download-url.md

# Method Description:

Gets a temporary download URL with a token for a specified file in the Media Manager.

The `getDownloadUrl()` function returns a Promise that resolves to 
 a download URL for a specified file in the Media Manager. 

 Pass the file's URL in the `fileUrl` parameter, as returned 
 in the `fileUrl` property of the `getFileInfo()`, `importFile()`, `upload()`, and `listFiles()` functions.
 When the download URL is clicked, the specified file downloads to your device. 

 You can use the `getDownloadUrl()` function to allow external clients to download a file from the Media Manager to their device.

 This function provides a temporary URL for downloading a single file.
 If you need permanent download URLs for one or more files, use the [`downloadFiles()`](#downloadFiles) function.

>**Notes:** 
> + The download URL with the token is valid for a single file download only. `getDownloadUrl()` must be called for each file that you want to download.
> + This function's parameters are positional, and must be specified in the sequence shown in the syntax below. When specifying a parameter, use `null` as a placeholder for any unspecified parameters. For example, to specify `downloadedFileName` only, call `getDownloadUrl(fileUrl, null, downloadedFileName, null)`.
