The company doesn't charge users for the feature, and Facebook is one of a myriad of tech companies are trying to carve out a space for themselves within the global payments industry.
This is the first time Messenger has extended p2p payments since launching in the U.S.in 2015 and since then, p2p payments in Messenger have been widely used to make life more seamless.
A Facebook spokesperson didn't share details with Recode but also didn't deny the existence of the mobile payment test, which was first discovered on November 3 by The Next Web's Matt Navarra.
"'With P2P [peer-to-peer] payments, this paves the path to us enabling small and large businesses to accept payments inside of Messenger", said David Marcus, who leads Facebook's Messenger team.
"In the US most people use payments in Messenger to send less than $50 at a time", Marcus said in a statement.
The money you send is transferred right away.
Sending and receiving dosh with Messenger sounds like a dawdle, according to Facebook's instructions. In order to send or request money, users can click on the payment option that appears in the messenger.
Have you ever gone somewhere with a friend and been in the position of forgetting your wallet, leaving your friend to pay for your coffee, drink, meal, or whatever?
It's a win-win situation: Facebook continues its relentless quest to take over the universe, and you'll eventually get to recklessly blow all your money on shite while you're drunk - without needing to change service. "Finally, Messenger payments are offered as a regulated payment service, meaning they're directly subject to consumer protection requirements".
So you'll be able to link when you sent over money to the relevant conversation with that person and also avoid the embarassment of having to chase them up for money if they owe you. Square has a similar product called Square Cash, and PayPal's Venmo has been a popular choice for younger users in particular.
