Photos: We can now shop via Twitter: It introduces a 'buy' button that allows users make a purchase directly from a tweet

Twitter has introduced a new ‘buy’ button that will allow users to make purchases directly through tweets.

The button, which is currently only available to a small percentage of U.S. users, will appear at the bottom right of partner tweets in the Twitter apps on iOS and Android.

To make a purchase you simply tap the button, review product details and enter your shipping and payment information at the prompt. Once complete, Twitter will send an order confirmation. 

‘An an entire purchase can be completed in just a few taps,’ the company boasts in a blog post introducing the feature.  

Twitter has partnered with social shopping platform, Fancy, ecommerce companies Gumroad and Musictoday, and mobile payment startup, Stripe to develop the functionality, and has rolled out the service with a number of notable brands, nonprofits and music artists. 

Current participants include Burberry, The Home Depot, Demi Lovato, Pharrell, Paramore and (RED), with more to come.

Facebook also announced it had been testing its own buy button back in July, though the feature has yet to roll out globally.
