In 2016, Facebook and PayPal began offering users an easier way to shop online in Facebook Messenger by using their PayPal account. The company has now expanded this feature, allowing users to choose PayPal and send or receive money directly within Facebook Messenger.
The integration is rolling out for customers residing in the United States. Previously, users could send and receive money using Facebook Messenger by linking their debit/credit card with Facebook, but integrating PayPal makes it a little more convenient.
In order to send/receive money, just tap on the blue plus icon, and then select the green Payments button to carry out the transaction. It's not limited to just a single person, users can even send money to a group of people.
