I have a developer who asked me to implement the ability to download a media from a private message.
After being refused due to the authentication information being required I noticed that the data sent from the twitter ton api was different if I was authenticated on Twitter.com compared to use the OAuth authentication credentials from a Twitter app.
It sems that the twitter.com version contains some kind of header. Would you please give me more information concerning this.
Here is the difference between the 2 files. On the left the twitter.com version, on the right the same file from the same url but using OAuth.
