I have no experience with this, but the API reference is here:

https://learn.microsoft.com/en-us/rest/api/appservice/web-apps/restart?view=rest-appservice-2023-12-01

I would personally get things working with Postman first, then migrate the REST call to AA.

That’s an interesting question, sravan.aluvala !

Hi ​@sravan.aluvala ,

Please find the below 

🔧 Prerequisites

1. Azure Subscription with access to the Web App.
2. App Registration in Azure AD (to get client_id, client_secret, and tenant_id).
3. Automation Anywhere A360 environment with access to the REST Web Services package.

🔐 Step 1: Register an App in Azure AD

1. Go to Azure Portal → Azure Active Directory → App registrations → New registration.
2. Name your app and register it.
3. Note down:
   • Application (client) ID
   • Directory (tenant) ID
4. Under Certificates & secrets, create a client secret and save it.

🔑 Step 2: Assign API Permissions

1. Go to your app → API permissions → Add a permission.
2. Choose Azure Service Management → Delegated permissions → user_impersonation.
3. Click Grant admin consent.

🔁 Step 3: Get Azure Access Token

Use the following REST API call in A360 to get the token:

• Method: POST
• URL:

  https://login.microsoftonline.com/{tenant_id}/oauth2/token
  

• Headers:
  Content-Type: application/x-www-form-urlencoded
• Body (form-data):

  grant_type=client_credentials
  client_id=YOUR_CLIENT_ID
  client_secret=YOUR_CLIENT_SECRET
  resource=https://management.azure.com/
  

🚀 Step 4: Restart the Azure Web App

Once you have the token, use this API call:

• Method: POST
• URL:

  https://management.azure.com/subscriptions/{subscription_id}/resourceGroups/{resource_group}/providers/Microsoft.Web/sites/{webapp_name}/restart?api-version=2022-03-01
  

• Headers:

  Authorization: Bearer <access_token>
  Content-Type: application/json
  

🤖 Step 5: Implement in Automation Anywhere A360

1. Use REST Web Services → POST to get the token.
2. Store the token in a variable.
3. Use another REST Web Services → POST to call the restart API.
4. Use Log to File or Message Box to confirm success.
