How can I list webapp extensions using Azure CLI?

I need to remove a Site Extension across ~50 Azure App Services.
The az webapp command space doesn’t list anything for Site Extensions: https://learn.microsoft.com/en-us/cli/azure/webapp?view=azure-cli-latest

The Azure team won’t touch Site Extensions: https://github.com/Azure/azure-cli/issues/7617

However, a comment shows it’s possible to delete the extension, if you know the resource ID: https://github.com/Azure/azure-cli/issues/7617#issuecomment-952743871

This command does not return installed extensions:

az resource list --resource-type Microsoft.Web/sites

And this command returns nothing:

az resource list --resource-type Microsoft.Web/sites/siteextensions

So how can I get a list of installed webapp extensions with Azure CLI?

    Even Iam unable to get the Extensions list with az resource list --resource-type Microsoft.Web/sites command.

    enter image description here

    Instead of az resource list use show az resource show.

    az resource show --resource-group 'YourRGName' --resource-type 'Microsoft.Web/sites/siteextensions'  --name 'mywebapp15June/siteextensions'

    enter image description here

    • This command work only if we provide the webapp name. At a time, we can retrieve only 1 webapp.
    • To retrieve the extensions for all the webapps, need to run the above command in loop.

    I have tried to run the command in loop using Bash.

    RG="YourRGName"
AppNames=$(az webapp list --resource-group $RG --query "[].name" -o tsv)

for AppName in $AppNames; do
    echo "WebApp: $AppName"
    
    # Retrieve the site extensions for the web app
    extensions=$(az resource show --resource-group $RG --resource-type Microsoft.Web/sites/siteextensions --name "$AppName/siteextensions")
    
    # Display the site extensions information
    echo "Site Extensions:"
    echo $extensions.title
    echo "=========================="
done

    Output:

    The webapps which has extensions installed will be listed.

    You can use WebApps -List Site Extensions REST API to pull the list of extensions installed in the specific webapp.

    You Need to write a custom script using the above rest API in PowerShell.

    Here is the sample script and please do modify it accordingly based on your requirement.

    Connect-AzAccount

$token = (Get-AzAccessToken).Token

$subcriptionId= "<SubscriptionId>"

$webapplist= Get-AzWebApp 

Write-output "List of webapp extensions installed:"

foreach ( $item in $webapplist) {

$url = 'https://management.azure.com/subscriptions/' + $subcriptionId + "/resourceGroups/" + $item.ResourceGroup + "/providers/Microsoft.Web/sites/" + $item.Name + "/siteextensions?api-version=2022-03-01"
 
$extension= Invoke-WebRequest -Method Get -Uri $url -Headers @{'authorization'= "Bearer " + $token } -ContentType "application/json" | Select -ExpandProperty Content
$installedextenstions = (ConvertFrom-Json $extension).value.name


Write-Output $installedextenstions
