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

If you're deploying the Logic Apps using ARM templates (e.g. edit in Visual Studio, check into Azure DevOps git repo and deploy using release pipeline), you can create an ARM parameter:

"resGroup_ARM": {
  "type": "string",
  "defaultValue": "[resourceGroup().name]",
  "metadata": {
    "description": "Resouce group name"
  }
}

Then, you can create a workflow parameter:

        "resGroup_LA": {
          "type": "string",
          "defaultValue": "ResGroup LA default"
        }

... and give it a value in the parameters initialisation section:

      "resGroup_LA": {
        "value": "[parameters('resGroup_ARM')]"
      }

You can get all the other properties of resourceGroup() in a similar manner, see: https://learn.microsoft.com/en-us/azure/azure-resource-manager/templates/template-functions-resource?tabs=json#resourcegroup

A simple formula may be:

split(workflow().id, "/")[4]

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:
