Facebook users will soon be able to use PayPal to buy advertising as well as credits for virtual gifts and games.
At the moment, anyone wishing to advertise on the site needs to use a credit card.
"For businesses in areas where the payment process can be difficult and expensive, the option to pay with PayPal makes it even easier for advertisers, particularly small international companies, to run campaigns on Facebook," the site said in a statement.
Facebook said this was important as 70 per cent of its 400 million users aren't based in the US.
PayPal will also be accepted for the new Facebook Credits system, the social networking site's own internal payment system. While it's still in testing in just a few games and applications, Facebook is hoping to roll it out across the site to buy virtual gifts or items in games.
Ethan Beard, director of Facebook's developer network, told IT PRO in December that Facebook Credit could one day be rolled out across the Connect network - a move which some think could lead to the system being used for micro-payments for access to pages like news articles.
PayPal will be available for a small number of users soon, a Facebook spokeswoman told IT PRO, and will "roll out more broadly over the coming weeks."
