Error 400 when using API (Update file info)

Hello,

I am trying to call the https://api.box.com/2.0/files/file_id api from an external tool. The requrement is to update the information of a file.

I tried the API call with a ReSt client, it worked fine but when I am trying to call the API from my external tool (with its Rest API Connector) I am receiving an "HTTP error code : 400" message.

Below some parameters I used :

Base Url: https://api.box.com/2.0/files
Media Type: application/json
Request Type: PUT
Authentication Type: OAUTH
Auth UserId: ***email address removed for privacy***
Auth Password: **********
OAuth Token Secret: *********

Can you please suggest.

Thanks, ZZ
