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

Aug 14, 2024 • 5 minute read

Hey there, fellow Ruby developer! Ready to supercharge your billing system with Chargebee? Let's dive right in and get that API integration up and running.

Introduction

Chargebee's API is a powerhouse for subscription management, and integrating it with your Ruby project is going to be a game-changer. Trust me, your future self will thank you for this.

Prerequisites

Before we start coding, make sure you've got:

Ruby 2.5 or higher (come on, you're not still on 1.9, right?)
A Chargebee account (if you don't have one, what are you waiting for?)

Installation

Let's kick things off by adding the Chargebee gem to your project. Pop this into your Gemfile:

gem 'chargebee'

Then hit the terminal with:

bundle install

Easy peasy, right?

Configuration

Time to set up those API keys. Create an initializer file (e.g., config/initializers/chargebee.rb) and add:

ChargeBee.configure(
  site: ENV['CHARGEBEE_SITE'],
  api_key: ENV['CHARGEBEE_API_KEY']
)

Pro tip: Use environment variables to keep your keys safe. No one likes a leaked API key!

Basic API Calls

Let's make our first API call. Here's how you can fetch a customer:

result = ChargeBee::Customer.retrieve("customer_id")
customer = result.customer
puts customer.first_name

Feels good, doesn't it?

Common Use Cases

Customer Management

Creating a customer is a breeze:

result = ChargeBee::Customer.create({
  first_name: "John",
  last_name: "Doe",
  email: "[email protected]"
})

Subscription Handling

Want to create a subscription? Here you go:

result = ChargeBee::Subscription.create({
  plan_id: "basic",
  customer_id: "john_doe"
})

Invoice Operations

Generating an invoice is just as easy:

result = ChargeBee::Invoice.create({
  customer_id: "john_doe"
})

Payment Processing

Collecting a payment? No sweat:

result = ChargeBee::Payment.create({
  amount: 1000,
  customer_id: "john_doe",
  currency_code: "USD"
})

Error Handling and Best Practices

Always wrap your API calls in a begin-rescue block. Chargebee throws specific exceptions, so catch them like this:

begin
  # Your API call here
rescue ChargeBee::InvalidRequestError => e
  puts "Oops! #{e.message}"
end

And remember, respect the API rate limits. Your server will thank you.

Webhooks Integration

Webhooks are your friends. Set up an endpoint in your app:

post '/chargebee_webhook' do
  event = ChargeBee::Event.deserialize(request.body.read)
  # Handle the event
end

Testing

Use Chargebee's test environment for development. It's like a sandbox, but for billing!

For unit tests, mock those API responses. Your CI/CD pipeline will love you for it.

Conclusion

And there you have it! You're now armed with the knowledge to integrate Chargebee into your Ruby project. Remember, the Chargebee API docs are your best friend for diving deeper.

Now go forth and bill with confidence! Your subscription management game just leveled up. 🚀💎
