Template:Construction API, also known as Application Programming Interface, is an ad system introduced in 2007 that allows users to generate revenue from their games and movies. Newgrounds has a partnership with CPMStar, an advertisement company, that allows users' flash games to earn revenue regardless of where people view the game or movie. This helps authors make money while still letting other websites choose to host their work. Revenue can be shared between multiple people. Flashes have unique IDs. Some ads pay based on how many views they get, some by how many click-throughs they get and some by how many customers buy something from the advertiser. Every version of Flash after 4 is supported. Parodies are allowed. Whenever authors make over $50, they are paid via check or paypal.
Work that reflects poorly on advertisers, such as adult material, racism, and stolen work, is ineligible.
