Step by Step Guide to Building a Salesforce Commerce Cloud API Integration in Ruby

Introduction

Hey there, fellow developer! Ready to dive into the world of Salesforce Commerce Cloud API integration with Ruby? You're in for a treat. This powerful combo will supercharge your e-commerce projects, giving you the ability to manage products, orders, and customers with ease. Let's get cracking!

Prerequisites

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

• A Ruby environment set up (you're a pro, so I'm sure you've got this covered)
• The necessary gems (we'll cover these soon)
• A Salesforce Commerce Cloud account with API credentials (if you don't have this, go grab a coffee while you wait for access)

Authentication: Your Golden Ticket

First things first, let's get you authenticated. We'll be using OAuth 2.0, because we're not savages.

require 'oauth2'

client = OAuth2::Client.new(YOUR_CLIENT_ID, YOUR_CLIENT_SECRET, site: 'https://account.demandware.com')
token = client.client_credentials.get_token

Boom! You've got your access token. Guard it with your life (or at least until it expires).

Setting Up Your Ruby Project

Let's get your project structure sorted. Create a new directory and initialize your Gemfile:

mkdir sfcc_integration && cd sfcc_integration
bundle init

Add these gems to your Gemfile:

gem 'oauth2'
gem 'faraday'
gem 'json'

Run bundle install and you're good to go!

Creating the API Client

Time to create our API client. We'll use Faraday because it's awesome.

require 'faraday'
require 'json'

class SFCCClient
  BASE_URL = 'https://your-instance.demandware.net/s/Sites-Site/dw/shop/v20_2'

  def initialize(access_token)
    @conn = Faraday.new(url: BASE_URL) do |faraday|
      faraday.headers['Authorization'] = "Bearer #{access_token}"
      faraday.headers['Content-Type'] = 'application/json'
      faraday.adapter Faraday.default_adapter
    end
  end

  # We'll add more methods here soon!
end

Implementing Key API Endpoints

Let's add some methods to interact with products, orders, and customers. Here's a taste:

class SFCCClient
  # ... previous code ...

  def get_product(product_id)
    response = @conn.get("products/#{product_id}")
    JSON.parse(response.body)
  end

  def create_order(order_data)
    response = @conn.post('orders', order_data.to_json)
    JSON.parse(response.body)
  end

  def get_customer(customer_id)
    response = @conn.get("customers/#{customer_id}")
    JSON.parse(response.body)
  end
end

Error Handling and Logging

Don't let errors catch you off guard. Let's add some error handling and logging:

class SFCCClient
  # ... previous code ...

  private

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

  def log_error(response)
    # Implement your logging logic here
    puts "Error: #{response.status} - #{response.body}"
  end
end

Testing Your Integration

You're not done until you've tested it! Here's a quick example using RSpec:

require 'rspec'
require_relative 'sfcc_client'

RSpec.describe SFCCClient do
  let(:client) { SFCCClient.new('your_access_token') }

  it 'fetches a product successfully' do
    product = client.get_product('some-product-id')
    expect(product).to have_key('id')
    expect(product['id']).to eq('some-product-id')
  end

  # Add more tests for other endpoints
end

Best Practices

Remember to:

• Implement rate limiting to avoid hitting API limits
• Use caching strategies for frequently accessed data
• Keep your access token secure and refresh it when needed

Conclusion

And there you have it! You've just built a Salesforce Commerce Cloud API integration in Ruby. Pat yourself on the back, you magnificent code wizard!

Remember, this is just the beginning. There's a whole world of SFCC API endpoints to explore. Keep experimenting, keep building, and most importantly, keep being awesome!

Happy coding! 🚀
