Send money via messenger
If you use a debit card or have a PayPal account, you can send money to one of your Facebook friends in Messenger. Pull up the person’s conversation and tap the +next to the message entry field to open a screen that includes Payments. Tap it and enter the amount you want to send, attach a note, and tap the Pay button. Enter your payment information as directed. Your payment is on the way, and your friend is notified.
This feature is handy when friends want to split a bill at a restaurant or owe half the rent to a roommate. The service is free and secure.
