    When the trigger is set to "Anyone", the flow requires authentication via a Shared Access Signature, which is already part of the URL in the sig parameter
    Try below steps which should resolve issue
    1. Use Full URL in PAD - Ensure the complete URL, including the sig parameter, is used in the Invoke Web Service action.
    Example format:
    https://prod-130.westus.logic.azure.com/.../invoke?...&sig=XXXXXXXXXXXXXXX
    2. Configure Invoke Web Service in PAD - 
    Set Method to POST.
    Paste the complete URL in the URL field.
    Set Header to Content-Type: application/json (if required).
    Ensure Proper Payload (if needed):
    3. Match the request body with the expected JSON format of the flow.
    4. Re-run the Action - Test the Invoke Web Service action in PAD to see if it works correctly.
