Players can buy virtual goods via Amazon accounts, while devs will have automatic access to fraud detection tools.
Amazon introduced in-app purchases to Appstore developers back in April, enabling users of the Kindle Fire and other Android devices to buy digital upgrades while playing games.
The online retail giant has now launched in-app purchases to Mac, PC, and web-based games. The expansion means customers will now be able to pay for virtual goods via an Amazon account when playing desktop games.
Customers can use any credit card, gift certificate or promo credit connected to existing Amazon accounts to buy in-app items, while developers will automatically receive access to Amazon's fraud detection tech.
What's more, in-app products will appear on the Amazon.com site in best seller lists , recommendations and more, offering extra means of app discovery.
Mike Frazzini, director of Amazon Games, said: "We’re passionate about making game developers successful, and we’ll continue to build services that make monetization easier and remove undifferentiated heavy lifting from developers.
"Game developers build games that are used across multiple platforms and mediums. In-App Purchasing for Mac, PC and Web-based games is our latest service that helps game developers grow their business and increase their customer-base. For years, Amazon has focused on making the online shopping experience as frictionless as possible, and we are excited to share this expertise and technology so that game developers can offer customers this same great experience.”
Just last month, Amazon announced that 23 of the top 25 grossing Appstore apps use its in-app purchasing tools.
