For creating a Logic App which will restart the Azure web app, you need the following items and access.

  1. Azure portal access where Azure web App is deployed.
  2. Tenant Id of your azure account
  3. Client_id
  4. Client_secret
  5. Azure Subscription Id
  6. Resource Group
  7. App name


Restarting of Azure web app using Azure logic app will have three simple steps, as shown below.

Three steps to restarting Azure web app

We will discuss, figure 1 steps in detail in the following section.

Start Designing of the Azure Logic App

Step 1 - Get Access Token (HTTP)

Firstly, we need to add the HTTP action in-order to generate and get the access token. This action is having a post method and requires tenant_id, client_id, client_secret.

"method": "POST"

"uri": "https://login.microsoftonline.com/{tenant_id}/oauth2/token"
"body": "&client_id={client_id} &client_secret{client_secret}&://management.core.windows.net/"

"Content-Type": "application/x-www-form-urlencoded"

After execution, we will get a JSON result which will have an access_token value which is required to restart the app.

JSON result looks like as below:

Step 2: Parse JSON

Parse the JSON and get the body and define the schema using the sample payload to generate the schema.

Step 3 - Restart App (HTTP)

For this HTTP request, we need a subscription ID, resource group, and app name of the Azure web app. We need to pass the access_token  from the previous step in the Authorization field.

"method": "POST"

"uri": "https://management.azure.com/subscriptions/{subscription_id}/resourceGroups/{resource_group}/providers/Microsoft.Web/sites/{webApp_name}/restart?-08-01"
"Authorization": "Bearer @{body('Parse_JSON')?['access_token']}",

"Content-Type": "application/json"

Expected Result

The Logic app is configured properly and worked as per expected. It is restarting the Azure web app, and we can configure this on-demand and schedule it. For on-demand, we can use email receiving event and restart it on receiving an email with a specific subject line. This process is presented below.

Automate the Logic App on Receiving an Email

To automate this process, we can configure the above Logic app to receive an email with some defined text in the subject. Now, whenever you will receive an email with a defined subject then the Logic app will run automatically.

Running app


In the above article, we saw how to restart the Azure web app using the logic app. We also saw how to use email receiving an event to restart the app. Apart from the restart, we can perform many more operations like stop, start, etc. For more triggered APIs, refer to the below URL and configure those in the above logic app accordingly.
