The Newgrounds Flash API is a set of tools that let developers earn revenue, protect their work, and integrate their games with the Newgrounds community.

Note: For modern, non-Flash web games, please see Newgrounds.io.

The API has lots of cool features, including:

• Flash ads, to earn revenue from your game or movie
• Site-locking, to control where your game is played
• Version control, to forward users to the newest version of your game
• Medals, for players to earn with their Newgrounds account
• Scoreboards, for players to compete for a top spot
• Save files, to store game data to a Newgrounds account
• File sharing, to let users share their content with others

The latest API packages are available in the API Tools section of a project in your Projects page.
