Recently, a customer asked about how to retrieve some details about the running Azure Logic Apps (Standard) instance. They were interested in some specific details that would help them populate error traces including:

  • Logic App URL
  • Logic App Name
  • Subscription
  • Workflow Name

The question now is how we go ahead and retrieve these values at runtime? The answer lies in expressions. However, some of the expressions used to obtain these values aren't visible, hence documenting it here. When it comes to Workflow Name, an existing property exists as part of the workflow() expression. But, for the others we can take advantage of the appsetting() expression.


Attribute Expression Example

Logic App URL


Logic App Name



Workflow Name
Hello World


Here is an example of how you can retrieve the Logic App's URL by using the appsetting() expression.



The next question is what other values can I take advantage of using this approach? All of the App Service app settings have been documented here: Environment variables and app settings reference - Azure App Service | Microsoft Learn.


Note: There may be some settings which are not relevant for Azure Logic Apps and as a result may not have been implemented.


But, we can look at the App Settings that have been included for your Logic Apps instance by viewing the App Settings for your Logic App (Standard) instance in Kudu. For instructions on how to access Kudu, please see the following post.
