Step by Step Guide to Building a UKG Pro Recruiting API Integration in Ruby

Hey there, fellow Ruby enthusiast! Ready to dive into the world of UKG Pro Recruiting API integration? Let's roll up our sleeves and get coding!

Introduction

UKG Pro Recruiting API is a powerful tool that lets you tap into a wealth of recruitment data. We're going to build an integration that'll make your recruiting process smoother than a freshly waxed surfboard.

Prerequisites

Before we jump in, make sure you've got:

• Ruby 2.7+ (because we're not savages)
• Your favorite HTTP client gem (I'm partial to faraday)
• json gem for parsing responses
• UKG Pro Recruiting API credentials (don't forget to keep these secret!)

Setting Up the Project

Let's get this party started:

mkdir ukg_pro_integration
cd ukg_pro_integration
bundle init

Now, crack open that Gemfile and add:

gem 'faraday'
gem 'json'

Run bundle install, and we're off to the races!

Authentication

First things first, let's get that access token:

require 'faraday'
require 'json'

class UKGProClient
  BASE_URL = 'https://api.ultipro.com'

  def initialize(client_id, client_secret)
    @client_id = client_id
    @client_secret = client_secret
  end

  def authenticate
    response = Faraday.post("#{BASE_URL}/oauth/token") do |req|
      req.body = {
        grant_type: 'client_credentials',
        client_id: @client_id,
        client_secret: @client_secret
      }
    end

    JSON.parse(response.body)['access_token']
  end
end

Pro tip: In a real-world scenario, you'd want to handle token expiration and refreshing. But let's keep it simple for now, shall we?

Making API Requests

Now that we're authenticated, let's make some noise:

def get_job_listings
  access_token = authenticate

  response = Faraday.get("#{BASE_URL}/recruiting/v1/job-openings") do |req|
    req.headers['Authorization'] = "Bearer #{access_token}"
  end

  JSON.parse(response.body)
end

Implementing Key Functionalities

Let's add a method to submit applications:

def submit_application(job_id, candidate_data)
  access_token = authenticate

  response = Faraday.post("#{BASE_URL}/recruiting/v1/applications") do |req|
    req.headers['Authorization'] = "Bearer #{access_token}"
    req.headers['Content-Type'] = 'application/json'
    req.body = {
      jobOpeningId: job_id,
      candidateData: candidate_data
    }.to_json
  end

  JSON.parse(response.body)
end

Error Handling and Logging

Don't let those pesky errors catch you off guard:

def api_request(method, endpoint, params = {})
  response = Faraday.send(method, "#{BASE_URL}#{endpoint}") do |req|
    req.headers['Authorization'] = "Bearer #{authenticate}"
    req.body = params.to_json if [:post, :put].include?(method)
  end

  handle_response(response)
rescue Faraday::Error => e
  log_error("API request failed: #{e.message}")
  raise "API request failed: #{e.message}"
end

def handle_response(response)
  case response.status
  when 200..299
    JSON.parse(response.body)
  else
    log_error("API error: #{response.status} - #{response.body}")
    raise "API error: #{response.status} - #{response.body}"
  end
end

def log_error(message)
  # Implement your logging logic here
  puts "ERROR: #{message}"
end

Testing the Integration

Time to put our code through its paces:

require 'minitest/autorun'
require 'webmock/minitest'

class UKGProClientTest < Minitest::Test
  def setup
    @client = UKGProClient.new('fake_id', 'fake_secret')
  end

  def test_authenticate
    stub_request(:post, "#{UKGProClient::BASE_URL}/oauth/token")
      .to_return(status: 200, body: '{"access_token":"fake_token"}')

    assert_equal 'fake_token', @client.authenticate
  end

  # Add more tests for other methods
end

Best Practices and Optimization

Remember, with great power comes great responsibility:

• Respect rate limits: Implement exponential backoff for retries.
• Cache responses when appropriate to reduce API calls.
• Use connection pooling for better performance.

Conclusion

And there you have it, folks! You've just built a lean, mean, UKG Pro Recruiting API integration machine. Remember, this is just the tip of the iceberg. There's a whole world of recruitment data out there waiting for you to explore.

Now go forth and recruit like a boss! 🚀
