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

Aug 7, 2024 • 5 minute read

Introduction

Hey there, fellow code wranglers! Ready to dive into the world of Freelancer API integration? You're in for a treat. The Freelancer API is a powerful tool that can open up a whole new realm of possibilities for your projects. Whether you're building a job aggregator, a freelance management system, or just want to flex your API muscles, this guide's got you covered.

Prerequisites

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

Ruby installed (I know you do, but just checking!)
Freelancer API credentials (grab 'em from the Freelancer developer portal)
Your favorite text editor at the ready

Setting up the project

Let's kick things off by creating a new Ruby project and installing the freelancer gem:

mkdir freelancer_integration
cd freelancer_integration
bundle init
echo "gem 'freelancer'" >> Gemfile
bundle install

Initializing the Freelancer client

Now, let's get that Freelancer client up and running:

require 'freelancer'

client = Freelancer::Client.new(
  oauth_key: 'YOUR_OAUTH_KEY',
  oauth_secret: 'YOUR_OAUTH_SECRET'
)

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

Basic API operations

Time to flex those API muscles! Here are some basic operations to get you started:

# Fetch user profile
user = client.users.get(user_id: 123)

# Search for projects
projects = client.projects.search(query: 'Ruby developer')

# Place a bid
bid = client.bids.create(
  project_id: 456,
  amount: 500,
  period: 7,
  description: 'I'm your Ruby guru!'
)

Handling API responses

The Freelancer API returns JSON responses. Here's how to handle them like a pro:

begin
  response = client.projects.get(project_id: 789)
  puts response.title
  puts response.description
rescue Freelancer::Error => e
  puts "Oops! #{e.message}"
end

Advanced features

Ready to level up? Let's tackle some advanced features:

# Pagination
projects = client.projects.search(query: 'Ruby', page: 2, limit: 20)

# Filtering results
projects = client.projects.search(
  query: 'Ruby',
  min_budget: 500,
  max_budget: 1000
)

# Webhook integration
webhook = client.webhooks.create(
  events: ['bid.created'],
  url: 'https://your-webhook-url.com'
)

Best practices

Remember, with great power comes great responsibility:

Respect rate limits (the gem handles this for you, but keep an eye out)
Cache responses when appropriate to reduce API calls
Keep your API credentials secure (seriously, don't commit them to GitHub!)

Testing the integration

Don't forget to test your integration! Here's a quick example using RSpec:

RSpec.describe 'Freelancer API Integration' do
  let(:client) { Freelancer::Client.new(oauth_key: 'test', oauth_secret: 'test') }

  it 'fetches a user profile' do
    VCR.use_cassette('user_profile') do
      user = client.users.get(user_id: 123)
      expect(user.id).to eq(123)
      expect(user.username).to eq('ruby_ninja')
    end
  end
end

Conclusion

And there you have it, folks! You're now armed with the knowledge to build a killer Freelancer API integration in Ruby. Remember, the API is your oyster – don't be afraid to explore and experiment.
