The first and most convenient: Appointment Booking, which is great news if you use Facebook and Instagram to find nail salons or dry bars, only to have to then Google them and make appointments via their individual websites (or worse, call them on the phone). Now, you can now your book appointment directly through Messenger by clicking the “Book Now” button on the business's Facebook page or with the “Book” button on the business's Instagram Profile, request the service you want, and confirm a time without ever leaving the app.
