Apple officially launched Apple Pay, its new payments product, via an update to iOS 8 today. Third-party apps are also getting updates to add support for it.

Groupon announced that it has updated its iPhone app to include it as a payment option. iPhone 6 and 6 Plus users in the U.S. can take advantage.

“To use the new payments service, existing customers need to download iOS 8.1, install Apple Pay, update the Groupon app and select Apple Pay on the purchase confirmation screen. New Groupon customers need to do the same and their method of payment will automatically default to Apple Pay,” Groupon says.

“With nearly 92 million app downloads worldwide and more than half of our transactions occurring on mobile devices, Groupon is one of the largest mobile commerce companies in the world,” says Groupon CEO Eric Lefkofsky. “Bringing Apple Pay to the Groupon mobile app makes it easier than ever to find and buy the best things around you.”

Groupon’s app is one of the 25 most-downloaded free apps in the App Store.
