According to this docs: https://developers.hubspot.com/docs/methods/files/get_files_file_id
we can get JSON with information about file, which is attached to deal for example, also here are some links like url or alt_url,
but when I try to go this link I get 403 Forbidden.
Hi @kremenetskyi, You can access the file via the HubSpot UI. Hidden files are not meant to be accessible outside of the UI, so I would recommend only working with these files via the UI wherever possible. *Edit: Corrected; it isn’t possible to un-hide files
