There’s been plenty of buzz lately about Pinterest’s new Buyable Pins, which aim to turn users from window shoppers into paying customers. If you haven’t heard, customers browsing Pinterest will soon be able to purchase items without leaving the mobile app by selecting a “buy it” button placed next to the iconic, red “pin it” button. This is an important step for Pinterest, as its evolution into an e-commerce platform helps justify the company’s $11 billion valuation.

Pinterest tapped PayPal-owned Braintree to be a part of the launch later this month. Many sources reported that Braintree’s role will be to simply “make sure Pinterest never touches credit card information.” Braintree’s role, however, will go deeper than that.

Braintree, which prides itself on making payments so easy that they fade into the background, will indeed handle the transmission and storage of credit card information to help Pinterest remain PCI compliant. However, the payments company will also take on a secondary role to enable Pinterest to accept PayPal as a payment option. Pinterest has also tapped Stripe and Apple Pay as payment options.

Buyable Pins will launch on mobile iOS devices later this month and will soon be available on desktop and Android platforms (though no word on when).

Braintree presented its developer platform, alongside parent company PayPal, at FinDEVr in San Francisco 2014.
