2. Add a "Call HTTP web service" action to your workflow.
3. Configure the action to make a GET request to the URL of the file you want to download.
4. Add a "Build Dictionary" action to the workflow.
5. Add a key-value pair to the dictionary with the key "Accept" and the value "application/octet-stream".
6. Add a key-value pair to the dictionary with the key "Authorization" and the value "Bearer {your access token}".
7. Add the dictionary to the "RequestHeaders" parameter of the "Call HTTP web service" action.
8. Add a "Send HTTP web service" action to the workflow.
9. Configure the action to store the response content in a variable.

$siteUrl = "https://yoursharepointsite.com"
$webUrl = "https://yoursharepointsite.com/subsite"
$filePath = "/sites/yourdocumentlibrary/yourfile.txt"

# Get the access token
$accessToken = Get-SPOToken -SiteUrl $siteUrl

# Make a GET request to download the file
$uri = "$webUrl/_api/web/GetFileByServerRelativePath(decodedurl='$filePath')/\$value"
$response = Invoke-RestMethod -Uri $uri -Headers @{ "Accept" = "application/octet-stream"; "Authorization" = "Bearer $accessToken" }

# Save the file to your local machine
$localPath = "C:\Users\yourusername\Downloads\yourfile.txt"
[System.IO.File]::WriteAllBytes($localPath, $response)

In this script, the Get-SPOToken function is used to get the access token for authentication. You can implement this function using the SharePoint Online PowerShell module or any other method that provides the access token.

Replace the siteUrl, webUrl, filePath, and localPath variables with the appropriate values for your SharePoint site, file, and local machine.

Run the PowerShell script to download the file from SharePoint to your local machine.

What is SharePoint Online Management Shell and how to use it for downloading files?

SharePoint Online Management Shell is a set of Windows PowerShell cmdlets that can be used to manage SharePoint Online within the Office 365 environment. It allows administrators to perform various tasks such as managing site collections, lists, libraries, users, and more.

To use SharePoint Online Management Shell for downloading files, you can follow these steps:

1. Launch SharePoint Online Management Shell: Open the SharePoint Online Management Shell application on your computer.
2. Connect to SharePoint Online: Use the Connect-SPOService cmdlet to connect to your SharePoint Online site. You will need to enter your SharePoint Online admin URL and credentials to establish a connection.
3. Navigate to the SharePoint document library: Use the Get-SPOFolder cmdlet to navigate to the document library where the file is located. You may need to specify the site URL and library name in the cmdlet.
4. Download the file: Use the Get-SPOFile cmdlet to download the file from the document library. You will need to specify the file name and destination path where you want to save the file on your local computer.

Example:

Connect-SPOService -Url https://yourtenant-admin.sharepoint.com
$folder = Get-SPOFolder -SiteRelativeUrl "/sites/your-site" -LibraryName "Documents"
Get-SPOFile -ServerRelativeUrl $folder.ServerRelativeUrl + "/file.pdf" -LocalFile "C:\Downloads\file.pdf"

In the example above, replace "https://yourtenant-admin.sharepoint.com" with your SharePoint Online admin URL, "/sites/your-site" with the site URL where the document library is located, "Documents" with the library name, "/file.pdf" with the file path within the library, and "C:\Downloads\file.pdf" with the local destination path.
