How to call Azure Logic app(standard) from Power Automate flow, facing 403 forbidden error

Hi Team,

I have a use case to call Azure logic app(Standard) workflow from Power app/automate.
But on direct https call i am getting 403 error for testing i have kept public access open.

Although, i am able to call Logic app workflow from any browser directly. (it is automictically using certificate).
I am aware that there Power app customer connection is only available for logic app (consumption plan).

If there is not solution and I am planning to use and test APIM in between, but it would increate the complexity for single use case.
I did find some old post for connection but those doesn't work anymore(azure might have update the service now).

Any suggestions for direct call?

    How to call Azure Logic app(standard) from Power Automate flow, facing 403 forbidden error
    Hi,
     
    Have you tried this?
     
    https://<your-app>.azurewebsites.net/api/<workflow-name>/triggers/<trigger-name>/run?code=<access-key>
     
     

    1. Use the Workflow URL with the code Parameter

    The simplest way for a direct call to the Logic App (Standard) workflow is to use the pre-generated URL that includes an authentication code.

    Steps:

    1. Get the Workflow URL:

      • Open your Logic App in the Azure portal.
      • Go to the workflow’s Overview section.
      • Copy the HTTP POST URL. It should look the above.
    2. Direct Call:

      • Use this URL in your HTTP request from Power Apps or Power Automate.
      • For example, in Power Automate’s HTTP action:
        • Method: POST
        • URI: Paste the copied URL
        • Headers: Add any headers your Logic App expects.
        • Body: Add the payload required by your Logic App.

    Pros:

    • Simple to set up.
    • No additional authentication is required.

    Cons:

    • Less secure as the code is embedded in the URL. If exposed, anyone with the URL can trigger the Logic App.
