This is a gem to pragmatically access your Netbox instance via it's API from Ruby. This gem is currently only compatible with Netbox v2.4 or newer.


Add this line to your application's Gemfile:

gem 'netbox-client-ruby'

And then execute:

$ bundle

Or install it manually:

$ gem install netbox-client-ruby



Put this somewhere, where it runs, before any call to anything else of Netbox. If you are using Rails, then this would probably be somewhere underneath /config.

require 'netbox-client-ruby'
NetboxClientRuby.configure do |config|
  config.netbox.auth.token = 'YOUR_API_TOKEN'
  config.netbox.api_base_url = 'http://netbox.local/api/'

  # these are optional:
  config.netbox.auth.rsa_private_key.path = '~/.ssh/netbox_rsa'
  config.netbox.auth.rsa_private_key.password = ''
  config.netbox.pagination.default_limit = 50
  config.faraday.adapter = Faraday.default_adapter
  config.faraday.request_options = { open_timeout: 1, timeout: 5 }
  config.faraday.logger = :logger # built-in options: :logger, :detailed_logger; default: nil


The methods are aligned with the API as it is defined in Netbox. You can explore the API endpoints in your browser by opening the API endpoint. Usually that's http://YOUR_NETBOX/api/.

So if the URL is /api/dcim/sites.json, then the corresponding Ruby code would be NetboxClientRuby.dcim.sites.


# configuration
NetboxClientRuby.configure do |c|
  c.netbox.auth.token = '2e35594ec8710e9922d14365a1ea66f27ea69450'
  c.netbox.api_base_url = 'http://netbox.local/api/'
  c.netbox.auth.rsa_private_key.path = '~/.ssh/netbox_rsa'

# get all sites
sites = NetboxClientRuby.dcim.sites
puts "There are #{} sites in your Netbox instance."

# get the first site of the result set
first_site = sites.first
puts "The first site is called #{}."

# filter devices by site
# Note that Netbox filters by *slug*
devices_of_site = NetboxClientRuby.dcim.devices.filter(site: first_site.slug)
puts "#{} devices belong to the site. #{devices_of_site}.length devices have been fetched."

# Finds a specific device
NetboxClientRuby.dcim.devices.find_by(name: 'my-device', other_field: 'other-value')

# Finds a specific device with a certain custom field
NetboxClientRuby.dcim.devices.find_by(cf_custom_url: '')

# Or a mix of regular and custom fields
NetboxClientRuby.dcim.devices.find_by(name: 'my-device', cf_custom_field: 'custom-value')

# get a site by id
s =

# update a site
s.update(name: 'Zurich', slug: 'zrh')

# update a site (alternative) = 'Amsterdam'
s.slug = 'ams'

# create a site
new_s = = 'Berlin'
new_s.slug = 'ber'

# create a site (alternative)
new_s = NetboxClientRuby::DCIM::Site
          .new(name: 'Berlin', slug: 'ber')

# delete a site
s =

# working with secrets
secrets = NetboxClientRuby.secrets.secrets
puts "#{} secrets are in your Netbox."
secrets[0].plaintext # => nil, because you have not yet defined a session_key
NetboxClientRuby.secrets.get_session_key # now get a session_key
secrets = NetboxClientRuby.secrets.secrets # you must reload the data from the server
secrets[0].plaintext # => 'super secret password'

# optionally, you can persist the session_key:
session_key = NetboxClientRuby.secrets.get_session_key.session_key
FILE_NAME = File.expand_path('~/.netbox_session_key').freeze
File.write(FILE_NAME, session_key)

# later on, you can restore the persisted session_key:
persisted_session_key =
NetboxClientRuby.secrets.session_key = persisted_session_key

If you can't find the object you need, also check the source code if it was added in the meantime without the list above having been updated.


After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests.

To install this gem onto your local machine, run bundle exec rake install.

To experiment interactively, fire up the Netbox Docker container by running docker-compose up -d. Then, run bin/console for an interactive prompt that will allow you to experiment against your local Netbox.

Load Development Data

To simplify development, e.g. via the bin/console described above, there is a very complete sample set of Netbox data readily available. You can use it to query almost every object and relation in Netbox.

docker exec -i netbox-client-ruby_postgres_1 psql -U postgres < dump.sql

Dump Development from Database

Should you want to export the current set of data, use the command below.

docker-compose exec postgres pg_dump -U netbox --exclude-table-data=extras_objectchange -Cc netbox > dump.sql

(Remove --exclude-table-data=extras_objectchange from the command if you want to retain the history!)
