Today we’re introducing Facebook Pay, which will provide people with a convenient, secure and consistent payment experience across Facebook, Messenger, Instagram and WhatsApp.

People already use payments across our apps to shop, donate to causes and send money to each other. Facebook Pay will make these transactions easier while continuing to ensure your payment information is secure and protected.

With Facebook Pay you can:

Add your preferred payment method once then use Facebook Pay where available to make payments and purchases on our apps, instead of having to re-enter your payment information each time
Set up Facebook Pay app-by-app, or choose to set it up for use across apps (where available) — that means we won’t automatically set up Facebook Pay across the apps you are active on, unless you choose to do so
View payment history, manage payment methods and update your settings in one place
Get real-time customer support via live chat in the US (and in more places around the world in the future)
Clearly understand which payment services are part of Facebook
Facebook Pay will begin rolling out on Facebook and Messenger this week in the US for fundraisers, in-game purchases, event tickets, person-to-person payments on Messenger and purchases from select Pages and businesses on Facebook Marketplace. And over time, we plan to bring Facebook Pay to more people and places, including for use across Instagram and WhatsApp.
