Facebook is expanding use of its "buy" button through merchants on the e-commerce platform Shopify, allowing consumers to purchase items from Shopify merchants on the social media site.
After about a year of testing the button concept with a small group of merchants, Shopify says it is offering the service to a larger group of U.S.-based Shopify merchants.
Facebook's move continues a trend in which buy buttons are increasingly appearing on social media sites. Twitter is working with Stripe for its Buy button; Pinterest is working with Stripe, Apple Pay and others; and Snapchat has a P2P capability from Square.
Facebook has also begun rolling out P2P payments within its Messenger app, a product headed by former PayPal president David Marcus. PayPal's Venmo also has elements of social media in the design of its app.
