I am developing pump.io stream social server on my iOS app. I am successfully logged-In, got access token and also get the logged-In user details using OAuth. But facing problem to POST new activity. Like i want to POST notes on public(feeds). I have done the same thing as pump.io mentioned in the document and my app URL which i am using to post new activity : https://hostname/api/user/nickname/feed and also add the OAuth Authorization in httpHeader.
How could i POST using OAuth?
