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

Introduction

Hey there, fellow Ruby enthusiast! Ready to supercharge your app with Leadpages? Let's dive into building a slick API integration that'll have you pulling lead data like a pro. We'll keep things snappy and to the point, so buckle up!

Prerequisites

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

• Ruby 2.7+ (because who doesn't love the latest and greatest?)
• Your favorite HTTP client gem (we'll use faraday in this guide)
• Leadpages API credentials (you've got these, right?)

Setting Up the Project

First things first, let's get our project off the ground:

mkdir leadpages_integration
cd leadpages_integration
bundle init

Now, crack open that Gemfile and add:

gem 'faraday'
gem 'json'

Run bundle install and we're cooking with gas!

Authentication

Leadpages uses OAuth 2.0, so let's grab that access token:

require 'faraday'
require 'json'

client_id = 'your_client_id'
client_secret = 'your_client_secret'

conn = Faraday.new(url: 'https://api.leadpages.io/oauth/token')
response = conn.post do |req|
  req.body = {
    grant_type: 'client_credentials',
    client_id: client_id,
    client_secret: client_secret
  }
end

token = JSON.parse(response.body)['access_token']

Pro tip: Store that token securely and handle refreshes like a champ!

Making API Requests

Now that we're authenticated, let's make some noise:

api = Faraday.new(url: 'https://api.leadpages.io/') do |f|
  f.headers['Authorization'] = "Bearer #{token}"
  f.headers['Content-Type'] = 'application/json'
end

# GET request
response = api.get('v3/leads')

# POST request
response = api.post('v3/leads') do |req|
  req.body = { email: '[email protected]' }.to_json
end

Implementing Key Leadpages API Endpoints

Let's put that API to work:

# Fetch leads
leads = JSON.parse(api.get('v3/leads').body)

# Create a new lead
new_lead = JSON.parse(api.post('v3/leads') do |req|
  req.body = { email: '[email protected]' }.to_json
end.body)

# Update a lead
updated_lead = JSON.parse(api.put("v3/leads/#{lead_id}") do |req|
  req.body = { first_name: 'John' }.to_json
end.body)

# Get landing page data
landing_page = JSON.parse(api.get("v3/landing_pages/#{page_id}").body)

Error Handling and Logging

Don't let those pesky errors catch you off guard:

begin
  response = api.get('v3/leads')
  raise unless response.success?
  # Handle successful response
rescue Faraday::Error => e
  puts "API request failed: #{e.message}"
  # Log error, retry, or handle gracefully
end

Testing the Integration

Test early, test often:

require 'minitest/autorun'
require 'webmock/minitest'

class LeadpagesIntegrationTest < Minitest::Test
  def setup
    @api = LeadpagesAPI.new(token: 'fake_token')
  end

  def test_fetch_leads
    stub_request(:get, "https://api.leadpages.io/v3/leads")
      .to_return(status: 200, body: '{"leads": []}')

    assert_equal [], @api.fetch_leads
  end
end

Best Practices and Optimization

• Respect rate limits like a good neighbor
• Cache responses to keep things zippy
• Use background jobs for heavy lifting

Conclusion

And there you have it! You're now armed and dangerous with a Leadpages API integration in Ruby. Remember, the API is your oyster – explore, experiment, and build something awesome. Happy coding, and may your leads be ever-flowing!
