Social e-commerce platform Chirpify today announced the rollout of its solution to brands widely on Facebook to power purchases through comments on the social network.

Chirpify debuted on Facebook last month through a promotion that let fans buy a special edition of country singer Tim McGraw’s “Two Lanes of Freedom” album. Among select brands named as launch partners on Tuesday were Adidas, the Portland Trailblazers, Major League Soccer’s Portland Timbers, bands Owl City and Neon Trees.

Through the platform, businesses and individuals can sell digital and physical items, seek donations and run giveaways directly within the Facebook news feed. Using the Chirpify dashboard, a user creates a listing with product information and pricing that will appear in both a brand page’s feed and those of its fans.

People who have signed up with Chirpify respond to a listing simply by typing in “buy,” “donate,” or “gimme” in the comments section depending on the type of promotion. In the case of the Tim McGraw album, for instance, a fan would simply type the word “buy” as a comment in response to the for-sale post in their feed. An email receipt is sent via email.

 Registering for Chirpify requires uses to enter their PayPal or credit card information along with shipping details for physical goods.

Founded in 2011, the company started by turning replies and comments on Twitter into transactions, before extending to Instagram, and now, Facebook. With its 1 billion users worldwide, Facebook obviously expands Chirpify-powered buying and selling to many more potential customers. It makes money by taking a 5% commission on items sold through its platform.
