How to get Resource Group name from within Logic App

In an Azure Logic App, how can I get the name of the Resource Group containing the current logic app?

I want to include some tracking details in the JSON output that I am sending to another system.

I can get the run Identifier ( using @{workflow()['run']['name']} ),

and the current logic app name ( using @{workflow()['name']} )

However, I cant work out how to get the name of the resource group to which the logic app is deployed.

As a last resort, I will use the resource group name used by the deployment template, but that will be wrong if the logic app is moved later. I could also use tags, but again that could get out of step if the logic app is moved.

Thanks

Solution

  • First we can create a "Initialize variable" action to get all of the data in workflow, shown as below screenshot:

    enter image description here

    Then we can find the data in workflow is:

    {
    "id": "/subscriptions/*****/resourceGroups/huryTest/providers/Microsoft.Logic/workflows/hurylogicblob",
    "name": "hurylogicblob",
    "type": "Microsoft.Logic/workflows",
    "location": "eastus",
    "tags": {},
    "run": {
        "id": "/subscriptions/*****/resourceGroups/huryTest/providers/Microsoft.Logic/workflows/hurylogicblob/runs/*****",
        "name": "*****",
        "type": "Microsoft.Logic/workflows/runs"
    }
}

    It contains the resource group name, so we just need to get the property "id" and substring it to get resource group name. The length of "resourceGroups/" is 15, so in the expression below I use add(,15) and sub(,15).

    You can use the expression as below:

    substring(workflow()['id'],add(indexOf(workflow()['id'],'resourceGroups/'),15),sub(sub(indexOf(workflow()['id'],'/providers'),indexOf(workflow()['id'],'resourceGroups/')),15))

    At last, I got the resource group name of the logic app:
