I am using an smarter track administrator account parameters to call the API from another internal site and API is successfully executed as well. So in the response the API call respond with an attachment download URL not the actual file. When I use that URL to access the attachment then it says "Invalid Permission". It only works if I am logged into smarter track website.

 

I wonder the downloadURL should be accessible without having to login again in smarter track or there should be an API that will direct the attachment to download without the URL or to implement a solution for downloading the attachment through the URL without needing to log in.
