'Forbidden' Error
{"http_code":403,"response_code":"FORBIDDEN","response_msg":"You need to be authenticated to access this file.","data":null}
If you receive this error message when trying to open a file you likely have your security settings set to 'Private'.
If private, you will only be able to access the files if authenticated via the API or logged into the dashboard.
You can change this back to public here: https://dashboard.clicksend.com/#/account/settings/security
If 'public' anyone with access to the random, long URL can open the file. It is still stored securely, but only people with the file name will be able to view it. It is technically secure because it's unlikely to be guessed by a random person.
