The upcoming Twitter's API release will aim at restricting consumer focused client applications in favor of business oriented ones, said the company's blog on Thursday. A Twitter group product manager, Michael sippey wrote that Twitter's 1.1 version of it's API (application programming interface) is scheduled for release in coming weeks, adding that developers will have six months to migrate their applications to new API.

Sippey wrote, "Nearly eighteen months ago, we gave developers guidance that they should not build client apps that mimic or reproduce the mainstream Twitter consumer client experience." Applications cited are Echofon, Tweetbot, Favstar. fm and Storify. Twitter will allow applications to double their token count. After that, developers will not be able to add additional users without Twitter's permission. Developers building new applications that want access to information such as home timelines and account settings and expect to need more than 100,000 tokens will have to ask for Twitter's approval as well.

Seppey added, "We will require you to work with us directly. One of the key things we've learned over the past few years is that when developers begin to demand an increasingly high volume of API calls, we can guide them toward areas of value for users and their businesses."
