Twitter is launching a pilot of the Shop Module. The Shop Module is a dedicated space at the top of a profile where businesses can showcase their products. When people visit a profile with the Shop Module enabled, they can scroll through the carousel of products and tap through on a single product to learn more and purchase - seamlessly in an in-app browser, without having to leave Twitter.
Now only a few brands will have access to this module. Furthermore, only users in the United States who use Twitter in English on iOS will be able to see the carousel
