This (unofficial) OpenSRS gem provides basic support to connect to, and utilize the OpenSRS API. This library has been well-tested in high-performance production environments.


  • Ruby >= 1.9.2 or >= 2.0.0 or >= 2.1.2


You can install this gem by doing the following:

$ gem install opensrs

You can then include it in a Ruby project, like so:

require 'opensrs'

For Rails 3.x and above, add it to the Gemfile:

gem 'opensrs'
gem 'nokogiri'    # if you want to use nokogiri as the XML parser
gem 'libxml-ruby' # if you want to use libxml as the XML parser


This library provides basic functionality for interacting with the OpenSRS XML API.

  • Connection handling
  • Error reporting
  • XML encoding
  • XML decoding

Currently, the library supports LibXML and Nokogiri as XML parsers. By default, it uses LibXML to parse and generate XML. If you'd like to use Nokogiri (1.4.7 and below) for parsing XML, then in one of your app initializers add the following line:

OpenSRS::Server.xml_processor = :nokogiri


OpenSRS::Server.xml_processor = :libxml

To connect, instantiate a new OpenSRS::Server object:

server =
  server:   "",
  username: "testing",
  password: "53cr3t",
  key:      "c633be3170c7fb3fb29e2f99b84be2410..."

NOTE: Connecting to OpenSRS requires that you add the IP(s) you're connecting from to their whitelist. Log in to the testing or production servers, and add your IP(s) under Profile Management > Add IPs for Script/API Access. IP changes take about one hour to take effect.

If you would like, you can provide OpenSRS::Server with a logger to write the contents of the requests and responses with OpenSRS. The assumption is you are using a Rails-like logger, but as long as your logger has an info method you are fine. You can simply assign the logger or pass it in as an initialization option:

server =
  server:   "",
  username: "testing",
  password: "53cr3t",
  key:      "c633be3170c7fb3fb29e2f99b84be2410...",
  logger:   Rails.logger

or, if you can change it later:

server.logger = Rails.logger

Once you have a server connection class, you can build from this to create the methods that you need. For instance, let's say we want to grab our account balance. The OpenSRS XML API takes a couple of attributes for all commands. You can include those here:

def get_balance
    action: "GET_BALANCE",
    object: "BALANCE"

Sometimes you might need to include attributes for the command, such as a cookie, or the data attributes themselves. You can do this, too:

def create_nameserver(nameserver)
    action: "CREATE",
    object: "NAMESERVER",
    cookie: "366828736:3210384",
    attributes: {
      name: nameserver.hostname,
      ipaddress: ""

Responses from OpenSRS are returned in an OpenSRS::Response object, which gives you access to a multitude of things.

Method Description
response.response This gives you the response in a Hash form, which is highly accessible to most other actions in your application.
response.response This gives you the response in a Hash form, which is highly accessible to most other actions in your application.
response.errors If there are errors which come back from OpenSRS, they are returned here. If not, it returns nil.
response.success? Returns true if the response was labeled as successful. If not, it returns false.
response.request_xml Returns raw request XML.
response.response_xml Returns raw response XML.
