Welcome to the Microsoft Q&A community.

To automate the execution of your PowerShell runbook as a pre-maintenance event before patching, and to run it on the created Hybrid Worker Group, follow these steps:

Step 1: Create and Publish the Runbook

1. Create the Runbook: Ensure your PowerShell runbook is created and published in your Azure Automation account.

Assign Permissions: Assign the necessary permissions to the managed identity used by the runbook.

Step 2: Create a Webhook for the Runbook

Navigate to the Runbook: Go to your Azure Automation account and select the runbook you want to automate.

Create Webhook: Under the "Runbook" page, select "Webhooks" and then "Add Webhook".

Configure Webhook: Provide a name for the webhook, set the expiration date, and copy the URL provided. This URL will be used to trigger the runbook.

Step 3: Configure Pre-Maintenance Event

Navigate to Maintenance Configuration: Go to Azure Update Manager and select the maintenance configuration where your Arc-enabled machine is added.

Add Pre-Maintenance Event: Under the "Events" tab, select "+Event Subscription" to create a pre-maintenance event.

Configure Event Subscription:

Event Type: Select "Pre Maintenance Event".

  **Endpoint Type**: Choose "Webhook".
  
     **Webhook URL**: Paste the webhook URL you copied earlier.
     
        **Event Schema**: Keep it as "Event Grid Schema".
        

Step 4: Configure Post-Maintenance Event

Repeat Steps for Post-Maintenance: Follow the same steps to create another runbook for starting the service after patching.

Create Webhook for Post-Maintenance Runbook: Create a webhook for this runbook as well.

Add Post-Maintenance Event: Under the "Events" tab, select "+Event Subscription" to create a post-maintenance event.

Configure Event Subscription:

Event Type: Select "Post Maintenance Event".

  **Endpoint Type**: Choose "Webhook".
  
     **Webhook URL**: Paste the webhook URL for the post-maintenance runbook.
     
        **Event Schema**: Keep it as "Event Grid Schema".
        

Step 5: Test the Configuration

1. Test Pre-Maintenance Event: Trigger the pre-maintenance event manually to ensure the runbook stops the app service as expected.
2. Test Post-Maintenance Event: Trigger the post-maintenance event manually to ensure the runbook starts the app service as expected.

By following these steps, you can automate the execution of your PowerShell runbooks as pre- and post-maintenance events on your Arc-enabled server using Azure Automation and Azure Update Manager.

Scratch my previous comment, got it, I missed to configure the parameter inside Webhook to run on Hybrid worker group, fixed that.

Thank you for the response.
