Avalara gem

This API provides access to the Avalara AvaTax API.

Setup

Add the gem to your Gemfile.

gem 'avalara'

Setup your Avalara credentials, either in a yml file, or as environment variables. If you want to add a yml file, it'll just need username and password:

username: 'testaccount'
password: 'testkey'

You can also specify a different endpoint for development mode:

endpoint: https://development.avalara.net

Setup the gem in an initializer (if using Rails), or wherever if you're not. You can load in your username/password however you want, but here's a sample way to do this:

file = File.new(File.join(Rails.root, 'config', 'avalara.yml'))

if file.exist?
  begin
    AVALARA_CONFIGURATION = YAML.load_file(path)
    Avalara.configure do |config|
      config.username = AVALARA_CONFIGURATION['username'] || abort("Avalara configuration file (#{path}) is missing the username value.")
      config.password = AVALARA_CONFIGURATION['password'] || abort("Avalara configuration file (#{path}) is missing the password value.")
      config.version = AVALARA_CONFIGURATION['version'] if AVALARA_CONFIGURATION.has_key?('version')
      config.endpoint = AVALARA_CONFIGURATION['endpoint'] if AVALARA_CONFIGURATION.has_key?('endpoint')
    end
  end
else
  abort "Avalara configuration not found."
end

Usage

After that you should be able to use a few endpoints to Avalaras tax service. If you need a new endpoint, feel free to fork this gem, add support for it, add specs and do a pull request back.

Geographical Tax

result = Avalara.geographical_tax('47.627935', '-122.51702', 100)

# Access the details of the result, which is a Avalara::Response::Tax object
result.rate
result.tax
result.tax_details

line = Avalara::Request::Line.new({  
  line_no: "1",
  destination_code: "1",

address = Avalara::Request::Address.new({

  line_1: "435 Ericksen Avenue Northeast",
  line_2: "#250",
  postal_code: "98110"
})

invoice = Avalara::Request::Invoice.new({
  doc_date: Time.now,
  company_code: 1,
  lines: [line],
  addresses: [address]
