Question: How to dynamically pass the URL from http request to actions in Azure Logic App?

I tried concat(triggerOutputs()?['relativePathParameters'], '/pet/findByStatus') but it does not work!

To keep it simple, I am just printing the @triggerOutputs()?['relativePathParameters'] to check it's value. Here is the full json. It returns null.

{
    "definition": {
        "$schema": "https://schema.management.azure.com/providers/Microsoft.Logic/schemas/2016-06-01/workflowdefinition.json#",
        "actions": {
            "Response": {
                "type": "Response",
                "kind": "Http",
                "inputs": {
                    "statusCode": 200,
                    "body": {
                        "url": "@triggerOutputs()?['relativePathParameters']"
                    }
                },
                "runAfter": {}
            }
        },
        "contentVersion": "1.0.0.0",
        "outputs": {},
        "triggers": {
            "When_a_HTTP_request_is_received": {
                "type": "Request",
                "kind": "Http"
            }
        }
    },
    "kind": "Stateful"
}

Hi Smith,

Thank you for reaching out on Microsoft Q&A!

It's not possible natively in Azure Logic Apps, however you can use the Microsoft Graph API to retrieve the URL of a Logic App. Please find the documentation below:
