Facebook has teamed up with Uber to allow its users to book a taxi directly from its Messenger app.
"Uber on Messenger" will start in the US later this week, allowing Facebook users to book an Uber taxi without leaving its platform. They will also not have to download the Uber app to use the service.
On its blog, Uber said: "With the ability to request, view, and pay for an Uber ride in Messenger, taking your next ride is as simple as sending a message.
Facebook said: "You can request a ride from a car service without ever needing to download an extra app or leave a conversation."
Describing the service as "super easy", Facebook added: "Driver status updates and payment receipts will get delivered to a private conversation between you and Uber.
"With everything in one place, you can seamlessly keep track of your ride and payment history."
To entice users to make use of the service, Facebook said the first ride - worth up to $20 - would be free.
Facebook has more than 1.5 billion users worldwide, 700 million of which use the Messenger app which was separated from the main app earlier this year.
