Gem Version Code Climate Build Status


Update 9/21/2015 - I have started working on the 1.0.0 release for this gem, this will include a complete test suite as well as UPS, FedEx, and USPS full integeration 1-to-1 with all basic features of these carriers. After this release, then I'll get into developing out the more advanced features of these carriers which will include full support for international shipping. If you wish to provide a suggestion for more carriers, please create an issue with the "feature" tag.

This gem is under active development, I'm only in the Alpha stage right now, so keep checking back for updates.

This library has been created to make web requests to common shipping carriers using XML. I created this to be easy to use with a nice Ruby API. This code was originally forked from the Shopify/active_shipping code, I began to strip it down cause I wan't a cleaner API along with the ability to actually create shipment labels with it. After changing enough code, I created this gem as its own project since it's different enough.

Supported Shipping Carriers

  • UPS
    • Create Shipment
    • Void Shipment
    • Get Rates
    • Validate Address
    • Validate Address with Street
  • FedEx (These listed features work, but still need more options added)
    • Create Shipment
    • Void Shipment
    • Get Rates

Simple example snippets

UPS Code Example

To run in test mode during development, pass :test => true as an option into create_shipment and accept_shipment.

  def create_shipment
  # If you have created the omniship.yml config file
  @config  = OMNISHIP_CONFIG[Rails.env]['ups']
  shipment = create_ups_shipment

def create_ups_shipment
  # If using the yml config
  ups =
  # Else just pass in the credentials
  ups = => @user, :password => @password, :key => @key)
  send_options = {}
  send_options[:origin_account] = @config["account"] # Or just put the shipper account here
  send_options[:service]        = "03"
  response = ups.create_shipment(origin, destination, package, options = send_options)
  return ups.accept_shipment(response)

def origin
  address = {}
  address[:name]     = "My House"
  address[:address1] = "555 Diagonal"
  address[:city]     = "Saint George"
  address[:state]    = "UT"
  address[:zip]      = "84770"
  address[:country]  = "USA"

def destination
  address = {}
  address[:company_name] = "Wal-Mart"
  address[:address1]     = "555 Diagonal"
  address[:city]         = "Saint George"
  address[:state]        = "UT"
  address[:zip]          = "84770"
  address[:country]      = "USA"

def packages
  # UPS can handle a single package or multiple packages
  pkg_list = []
  weight = 1
  length = 1
  width  = 1
  height = 1
  package_type = "02"
  pkg_list <<,[length.to_i,width.to_i,height.to_i],:units => :imperial, :package_type => package_type)
  return pkg_list


Currently this is on my TODO list. Check back for updates

Change Log


  • Bug fixes for UPS
  • Updated syntax for gemspec
  • Updated dependencies


  • Bug fixes for dependencies


Before anyone starts contributing, I want to get a good stable version going and tests to follow, after I get that going then for the features you add, you should have both unit tests and remote tests. It's probably best to start with the remote tests, and then log those requests and responses and use them as the mocks for the unit tests.

To log requests and responses, just set the logger on your carrier class to some kind of Logger object:

Omniship::USPS.logger =$stdout)

(This logging functionality is provided by the PostsData module in the active_utils dependency.)

After you've pushed your well-tested changes to your github fork, make a pull request and we'll take it from there!
