Heroku Ruby Client

The Heroku Ruby Client is used to interact with the Heroku Legacy API from Ruby.

Where possible we recommend interacting instead with the Heroku Platform API. You can use the Ruby client with the Platform API (or just install the gem).

Build Status


Start by creating a connection to Heroku with your credentials:

require 'heroku-api'

heroku = => API_KEY)                           # use API Key
heroku = => USERNAME, :password => PASSWORD)  # use username and password
heroku = => {'User-Agent' => 'custom'})        # use custom header

NOTE: You can leave out the :api_key if ENV['HEROKU_API_KEY'] is set instead.

Now you can make requests to the api.


What follows is an overview of commands you can run for the client.

For additional details about any of the commands, see the API docs.


heroku.delete_addon(APP, ADD_ON)    # remove the ADD_ON add-on from the app named APP
heroku.post_addon(APP, ADD_ON)      # add ADD_ON add-on to an the app named APP
heroku.put_addon(APP, ADD_ON)       # update the ADD_ON add-on on the app named APP
heroku.get_addons                   # see a listing of all available add-ons
heroku.get_addons(APP)              # see listing of installed add-ons for the app named APP


heroku.delete_app(APP)                  # delete the app named APP
heroku.get_apps                         # get a list of your apps
heroku.get_app(APP)                     # get info about the app named APP
heroku.get_dyno_types(APP)              # get dyno types for the app named APP    
heroku.post_app                         # create an app with a generated name and the default stack
heroku.post_app_maintenance(APP, '1')   # toggle maintenance mode for the app named APP
heroku.post_app('name' => 'app')        # create an app with a specified name, APP
heroku.put_app('name' => 'myapp')       # update an app to have a different name


heroku.delete_collaborator(APP, '')   # remove '' collaborator from APP app
heroku.get_collaborators(APP)                          # list collaborators for APP app
heroku.post_collaborator(APP, '')     # add '' collaborator to APP app

Config Variables

heroku.delete_config_var(APP, KEY)               # remove KEY key from APP app
heroku.get_config_vars(APP)                      # get list of config vars for APP app
heroku.put_config_vars(APP, KEY => 'value')      # set KEY key to 'value' for APP app


heroku.delete_domain(APP, '')   # remove the '' domain from the APP app
heroku.get_domains(APP)                    # list configured domains for the APP app
heroku.post_domain(APP, '')     # add '' domain to the APP app


heroku.delete_key('user@hostname.local') # remove the 'user@hostname.local' key
heroku.delete_keys                       # remove all keys
heroku.get_keys                          # list configured keys
heroku.post_key('key data')              # add key defined by 'key data'


heroku.get_logs(APP) # return logs information for APP app


heroku.get_ps(APP)                               # list current dynos for APP app
heroku.post_ps(APP, 'command')                   # run 'command' command in context of APP app
heroku.post_ps_restart(APP)                      # restart all dynos for APP app
heroku.post_ps_scale(APP, TYPE, QTY)             # scale TYPE type dynos to QTY for APP app
heroku.post_ps_stop(APP, 'ps' => 'web.1')        # stop 'web.1' dyno for APP app
heroku.post_ps_stop(APP, 'type' => 'web')        # stop all 'web' dynos for APP app
heroku.post_ps_restart(APP, 'ps' => 'web.1')     # restart 'web.1' dyno for APP app
heroku.put_dynos(APP, DYNOS)                     # set number of dynos for bamboo app APP to DYNOS
heroku.put_workers(APP, WORKERS)                 # set number of workers for bamboo app APP to WORKERS
heroku.post_ps_scale(APP, 'worker', WORKERS)     # set number of workers for cedar app APP to WORKERS
heroku.put_formation(APP, 'web' => '2X')         # set dyno size to '2X' for all 'web' dynos for APP app


heroku.get_releases(APP)       # list of releases for the APP app
heroku.get_release(APP, 'v#')  # get details of 'v#' release for APP app
heroku.post_release(APP, 'v#') # rollback APP app to 'v#' release


heroku.get_stack(APP)          # list available stacks
heroku.put_stack(APP, STACK) # migrate APP app to STACK stack


heroku.get_user                  # list user info


For testing (or practice) you can also use a simulated Heroku account:

require 'heroku-api'

heroku = => API_KEY, :mock => true)

Commands will now behave as normal, however, instead of interacting with your actual Heroku account you'll be interacting with a blank test account. Note: test accounts will have NO apps to begin with. You'll need to create one:

heroku.post_app(:name => 'my-test-app')


To run tests, first set ENV['HEROKU_API_KEY'] to your api key. Then use bundle exec rake to run mock tests or MOCK=false bundle exec rake to run integration tests.
