With Heroku Platform API, Heroku provides you with the ability to call the Heroku platform services to do virtually anything you need to do on Heroku—creating an application, checking the release history of your app, or plugging new add-ons in to your application. All this and more just by using simple HTTP. The following diagram depicts the interaction between a simple Heroku API client and the Heroku platform services. An API client can use the Heroku API to interact the core platform services of Heroku using a well-defined interface.

The Heroku Platform API allows you to do almost everything you can do with the Heroku command line or dashboard. This API is a powerful tool for application developers to leverage the capabilities of Heroku's features and gain complete control of their apps, from creating to monitoring them.
