Step by Step Guide to Building a systeme.io API Integration in Ruby

Introduction

Hey there, fellow developer! Ready to dive into the world of systeme.io API integration? You're in for a treat. This guide will walk you through building a robust integration in Ruby, allowing you to tap into the power of systeme.io's features. Let's get cracking!

Prerequisites

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

• Ruby 2.7+ installed
• The httparty and dotenv gems
• Your systeme.io API key (keep it secret, keep it safe!)

Setting up the project

First things first, let's set up our project:

mkdir systeme_io_integration
cd systeme_io_integration
bundle init

Add these to your Gemfile:

gem 'httparty'
gem 'dotenv'

Then run:

bundle install

Authentication

Create a .env file in your project root:

SYSTEME_IO_API_KEY=your_api_key_here

Now, let's create an authentication helper:

require 'dotenv/load'
require 'httparty'

module SystemeIO
  class Client
    include HTTParty
    base_uri 'https://systeme.io/api/v2'

    def initialize
      @options = {
        headers: {
          'X-Api-Key' => ENV['SYSTEME_IO_API_KEY'],
          'Content-Type' => 'application/json'
        }
      }
    end

    # We'll add more methods here soon!
  end
end

Making API requests

Let's add some methods to our Client class:

def get(path)
  self.class.get(path, @options)
end

def post(path, body)
  self.class.post(path, @options.merge(body: body.to_json))
end

def put(path, body)
  self.class.put(path, @options.merge(body: body.to_json))
end

def delete(path)
  self.class.delete(path, @options)
end

Implementing key systeme.io API endpoints

Now, let's add some endpoint-specific methods:

def get_contacts
  get('/contacts')
end

def create_product(product_data)
  post('/products', product_data)
end

def update_order(order_id, order_data)
  put("/orders/#{order_id}", order_data)
end

def delete_campaign(campaign_id)
  delete("/campaigns/#{campaign_id}")
end

Error handling and rate limiting

Let's add some error handling to our Client class:

def handle_response(response)
  case response.code
  when 200..299
    response
  when 429
    raise 'Rate limit exceeded. Try again later.'
  else
    raise "API error: #{response.code} - #{response.message}"
  end
end

Update your request methods to use this:

def get(path)
  handle_response(self.class.get(path, @options))
end

# Do the same for post, put, and delete methods

Testing the integration

Here's a quick test script:

client = SystemeIO::Client.new

begin
  contacts = client.get_contacts
  puts "Fetched #{contacts['data'].length} contacts"
rescue => e
  puts "Error: #{e.message}"
end

Best practices and optimization

Consider implementing caching for frequently accessed data:

require 'redis'

def get_cached_contacts
  redis = Redis.new
  cached = redis.get('contacts')
  return JSON.parse(cached) if cached

  contacts = get_contacts
  redis.set('contacts', contacts.to_json, ex: 3600) # Cache for 1 hour
  contacts
end

Conclusion

And there you have it! You've just built a solid foundation for your systeme.io API integration in Ruby. Remember, this is just the beginning – there's so much more you can do with the API. Keep exploring, keep coding, and most importantly, have fun with it!
