If you are the curious type, you may have noticed a "API" tab in your Account > Profile Settings page. API is an acronym for "Application Programming Interface". We have recently added this core functionality so we can more quickly and easily integrate our systems and services with our partners and other premium services.
Although you can already generate "API Access Keys" with this page, as of right now doing so will not actual "do" anything. But it will not hurt anything either (grin).
Watch for upcoming announcements regarding new integrations with supported services that are now possible due to this update.
