unable to delete public key certificates from appservice through powershell,cli and restapi.pipeline is getting successful but still certificate is not being deleted.

Hello,

Welcome to Microsoft Q&A,

Step 1: Check for Resource Locks

Locked resources prevent modifications or deletions.

• List locks

    Get-AzResourceLock -ResourceGroupName "<ResourceGroupName>"
  

• If a lock exists, remove it:

    Remove-AzResourceLock -LockId "<LockId>"
  

Step 2: Identify Dependencies

Bindings, custom domains, or other configurations may reference public key certificates.

• List all SSL bindings for the app:

    az webapp config ssl list --resource-group <ResourceGroupName> --name <AppName>
  

• If the certificate is bound to a hostname, remove the binding:

    az webapp config hostname delete --resource-group <ResourceGroupName> --webapp-name <AppName> --hostname <Hostname>
  

Step 3: Force Certificate Deletion

If the certificate is not bound or locks are removed, but it still cannot be deleted, force deletion might be necessary.

az webapp config ssl delete --certificate-thumbprint <Thumbprint> --resource-group <ResourceGroupName>

Remove SSL Binding:
Execute the command to remove any SSL bindings associated with the certificate:

Remove-AzWebAppSSLBinding -ResourceGroupName "YourResourceGroup" -WebAppName "YourWebApp" -Name "YourDomainName"

Delete Certificate:
After removing the binding, attempt to delete the certificate again using:

Remove-AzWebAppCertificate -ResourceGroupName "YourResourceGroup" -Name "YourCertificateName"
