Connect to UKG Pro HCM Data in Ruby

The CData API Driver for ODBC makes it easy to integrate connectivity to live UKG Pro HCM data in Ruby. This article shows how to create a simple Ruby app that connects to UKG Pro HCM data, executes a query, and displays the results.

Create an ODBC Connection to UKG Pro HCM Data

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

Start by setting the Profile connection property to the location of the UKGProHCM Profile on disk (e.g. C:\profiles\UKGProHCM.apip). Next, set the ProfileSettings connection property to the connection string for UKGProHCM (see below).

UKGProHCM API Profile Settings

UKG Pro HCM uses Basic authentication combined with a customer API key to authorize access to the API. To connect, you will need your UKG Pro HCM credentials and a customer API key issued by UKG.

Set the following connection properties to authenticate:

• AuthScheme: Set this to Basic.
• User: Set this to your UKG Pro HCM username.
• Password: Set this to your UKG Pro HCM password.
• ProfileSettings: Set this to a semicolon-separated list containing:
  • Host: Your UKG Pro HCM tenant hostname (e.g., yourcompany.ultipro.com).
  • CustomerAPIKey: Your UKG customer API key. This is passed as the US-CUSTOMER-API-KEY request header on each API call.

To obtain your customer API key, contact your UKG Pro HCM administrator or refer to the UKG Developer Portal at https://developer.ukg.com.

Installing Ruby and Necessary Gems

If you do not have Ruby installed, refer to the Ruby installation page. With Ruby installed, you will need to install the ruby-dbi, dbd-odbc, and ruby-odbc gems:

gem install dbi
gem install dbd-odbc
gem install ruby-odbc

Create a Ruby App with Connectivity to UKG Pro HCM Data

Create a new Ruby file (for example: APISelect.rb) and open it in a text editor. Copy the following code into your file:

#connect to the DSN
require 'dbi'
cnxn = DBI.connect('DBI:ODBC:CData API Source','','')

#execute a SELECT query and store the result set
resultSet = cnxn.execute("SELECT UserId, UserName FROM UserDetails WHERE UserStatus = 'A'")

#display the names of the columns
resultSet.column_names.each do |name|
  print name, "\t"
end
puts

#display the results
while row = resultSet.fetch do
  (0..resultSet.column_names.size - 1).each do |n|
    print row[n], "\t"
  end
  puts
end
resultSet.finish

#close the connection
cnxn.disconnect if cnxn

With the file completed, you are ready to display your UKG Pro HCM data with Ruby. To do so, simply run your file from the command line:

ruby APISelect.rb
