Twitter changed how applications are authorized to access its services back in May and this means that most apps and services will no longer be able to access your direct messages from June 30.
Twitter is doing this because there are thousands of apps within the Twitter ecosystem and the majority have no need to access direct messages. These include a number of services or apps such as Klout, Instagram, Foursquare, LinkedIn, Lockerz, Twitpic, YFrog, Tumblr, Posterous, WordPress, and just about every other app that lets you cross post content to Twitter without actually acting as a Twitter client the way Twitter’s own apps do.
Third party applications such as Tweetbot, Twitterrific, Seesmic, Hootsuite, Osfoora, Destroy Twitter, Twicca, SocialScope and many others are actual clients that let you access Twitter just as you would on its website or the official apps but with additional features, and these apps require access to your direct message so you can read or send them.
From June 30, you will no longer be able to send or receive direct messages using these apps because of the way Twitter changed its access permissions and terms of service unless the developers of these apps have updated their respective apps to comply with its new terms.
If you find yourselves locked out of your direct message from June 30 while using a non-official Twitter app, check if there’s an update and quickly update your app. Otherwise you’ll need to use Twitter’s official applications for your device.
Twitter has official apps for Mac OS X, iPhone, iPad, BlackBerry, Android, and Windows Phone 7. TweetDeck is also an official Twitter application.
