I can´t send updates that begin with @ (mentions) using https://api.twitter.com/1.1/statuses/update.json through my php application. If the tweet begin with other character it works, but if it begin with @ it doesn´t work and twitter doesn’t return any error.
I have “Read, Write and Access direct messages” permision in my application.
What I’m doing wrong? or How can I send mentions through API 1.1?
