Step by Step Guide to Building a OneLogin API Integration in Ruby

Aug 7, 2024 • 5 minute read

Introduction

Hey there, fellow developer! Ready to dive into the world of OneLogin API integration with Ruby? You're in for a treat. OneLogin's API is a powerhouse for managing user authentication and access, and pairing it with Ruby's elegance is a match made in code heaven. Let's get cracking!

Prerequisites

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

A Ruby environment up and running (you've got this, right?)
A OneLogin account with API credentials (if not, go grab those real quick)

Installation

First things first, let's get the OneLogin gem installed:

gem install onelogin

Easy peasy, right?

Authentication

Now, let's set up those API credentials:

require 'onelogin'

OneLogin.configure do |config|
  config.client_id = 'YOUR_CLIENT_ID'
  config.client_secret = 'YOUR_CLIENT_SECRET'
  config.region = 'us'  # or 'eu' if you're across the pond
end

Pro tip: Keep those credentials safe! Use environment variables or a secure config file.

Basic API Operations

Time to initialize the client and make some API calls:

client = OneLogin::Api::Client.new

# GET request
users = client.get_users

# POST request
new_user = client.create_user(
  email: '[email protected]',
  firstname: 'New',
  lastname: 'User'
)

# PUT request
client.update_user(user_id, { firstname: 'Updated' })

# DELETE request
client.delete_user(user_id)

See how smooth that is? Ruby's got your back!

Common Use Cases

Let's tackle some everyday tasks:

User Management

# Create a user
new_user = client.create_user(user_params)

# Get user details
user = client.get_user(user_id)

# Update user
client.update_user(user_id, update_params)

# Delete user
client.delete_user(user_id)

Group Management

# Get all groups
groups = client.get_groups

# Add user to group
client.add_user_to_group(user_id, group_id)

Role Assignments

# Assign role to user
client.assign_role_to_user(user_id, role_id)

Error Handling

Don't let errors catch you off guard:

begin
  client.get_user(user_id)
rescue OneLogin::Api::Error => e
  puts "Oops! #{e.message}"
end

Best Practices

Respect rate limits: OneLogin's not a fan of spam!
Keep your credentials secret: Treat them like your Netflix password.
Use pagination for large datasets: Your RAM will thank you.

Testing

Always test your integrations:

require 'minitest/autorun'

class TestOneLoginIntegration < Minitest::Test
  def setup
    @client = OneLogin::Api::Client.new
  end

  def test_get_users
    users = @client.get_users
    assert_instance_of Array, users
  end
end

Advanced Topics

Want to level up? Look into:

Implementing pagination for large datasets
Setting up webhooks for real-time updates
Creating custom wrappers for frequently used operations

Conclusion

And there you have it! You're now armed and ready to integrate OneLogin's API into your Ruby projects. Remember, the API docs are your best friend for diving deeper. Now go forth and code something awesome!

Happy integrating!
