Hi Guys,

I'm having a problem downloading attachments using Chatter Rest API. When I tried to get the feed item response I get the download URL and used the url for my download. I'm having an error SESSION is invalid. What I want is get the attachments link and view it in my browser page. 

Hi Everyone,

I am trying to upload a file in Chatter by REST API using request body - Since we are not able to send @Mention text with request parameter, we are using request body instead of request parameter to send the file Attachment with feed text having @Mentions together.

Please reply it, if anybody has worked on similar problem earlier or has any clue for resolution.

So the problem im having is when a user on my applicaiton clicks to download a file attached to a chatter post it prompts them to login. is there a way to add the session id or oauth token to the request to allow the file to be served the file to people.
