Destroying an App
If you are no longer using an application, it should be destroyed to avoid paying for unused resources.
Danger
Destroying an application destroys everything related to the application. If you've configured add-ons which are storing data (database, Redis, S3, etc.), all data in those stores will be erased. Be sure to back up any data to a separate location before destroying the application.
When you're ready to destroy your application, you can use the apppack destroy app
command. Only administrators can perform this action.
Example
apppack destroy app my-app
