Restore your deleted, non-solution canvas app via PowerShell

Restoring a standalone (non-solution) canvas app using PowerShell involves leveraging the Power Apps Administration PowerShell module. Here’s a breakdown of the process:

Prerequisites:

• PowerShell Modules: Ensure you have the Microsoft.PowerApps.Administration.PowerShell and Microsoft.PowerApps.PowerShell modules installed.
• Permissions: You must have appropriate permissions to manage canvas apps in your Power Apps environment.

Steps:

1. Connect to Power Apps: PowerShellAdd-PowerAppsAccount This command will prompt you to authenticate with your Power Apps credentials.
2. Get Deleted Apps: PowerShellGet-AdminApp -EnvironmentName "YourEnvironmentName" -Deleted Replace "YourEnvironmentName" with the actual name of your Power Apps environment. This command retrieves a list of deleted canvas apps within that environment.
3. Identify the App:
   • Examine the output of the Get-AdminApp command.
   • Locate the app you want to restore.
   • Note the AppName (the app’s GUID).
4. Restore the App: PowerShellRestore-AdminApp -EnvironmentName "YourEnvironmentName" -AppName "AppGUID" Replace "YourEnvironmentName" with your environment name and "AppGUID" with the AppName you noted in the previous step.

Example:

PowerShell

Add-PowerAppsAccount

$environmentName = "MyDevEnvironment"
$deletedApps = Get-AdminApp -EnvironmentName $environmentName -Deleted

if ($deletedApps) {
    Write-Host "Deleted Canvas Apps:"
    $deletedApps | Format-Table DisplayName, AppName, LastModifiedTime

    $appToRestore = Read-Host "Enter the AppName (GUID) of the app to restore"

    Restore-AdminApp -EnvironmentName $environmentName -AppName $appToRestore

    Write-Host "Canvas app restored successfully."
} else {
    Write-Host "No deleted canvas apps found."
}

Explanation:

• The script begins by connecting to your Power Apps account.
• It then retrieves a list of deleted canvas apps from the specified environment.
• It displays the deleted apps, including their display names and GUIDs.
• The user is prompted to enter the GUID of the app to restore.
• The Restore-AdminApp command is used to restore the selected app.
• The script also includes error handeling, to inform the user if no deleted apps are found.

Important Notes:

• Ensure you have the correct environment name and app GUID.
• The restoration process might take some time.
• It is always best practice to add canvas apps into solutions, so they are easier to manage, and backup.
• Keep your PowerShell modules up to date.

By following these steps, you can effectively restore deleted standalone canvas apps using PowerShell.
