Step by Step Guide to Building an OpenPhone API Integration in Ruby

Introduction

Hey there, fellow developer! Ready to supercharge your Ruby project with OpenPhone's powerful communication features? You're in the right place. We're going to walk through building an OpenPhone API integration that'll have you managing contacts, handling messages, and juggling phone numbers like a pro. Let's dive in!

Prerequisites

Before we get our hands dirty, make sure you've got:

• Ruby 2.7+ installed
• The httparty gem (we'll use this for API requests)
• Your OpenPhone API credentials (if you don't have these yet, hop over to the OpenPhone developer portal)

Setting up the project

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

mkdir openphone_integration
cd openphone_integration
bundle init

Now, add this to your Gemfile:

gem 'httparty'

And run:

bundle install

Authentication

Alright, time to get cozy with the OpenPhone API. Create a new file called openphone_client.rb:

require 'httparty'

class OpenPhoneClient
  include HTTParty
  base_uri 'https://api.openphone.com/v1'

  def initialize(api_key)
    @options = { headers: { 'Authorization' => "Bearer #{api_key}" } }
  end

  # We'll add more methods here soon!
end

Basic API Operations

Let's add a method to make GET requests:

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

Now you can make API calls like this:

client = OpenPhoneClient.new('your_api_key_here')
response = client.get('/contacts')

Implementing Key Features

Managing Contacts

Let's add some contact management methods:

def create_contact(name, phone_number)
  self.class.post('/contacts', @options.merge(body: { name: name, phone_number: phone_number }))
end

def get_contact(contact_id)
  get("/contacts/#{contact_id}")
end

def update_contact(contact_id, updates)
  self.class.patch("/contacts/#{contact_id}", @options.merge(body: updates))
end

Handling Messages

Now for some messaging magic:

def send_message(to, body)
  self.class.post('/messages', @options.merge(body: { to: to, body: body }))
end

def get_conversations
  get('/conversations')
end

Managing Phone Numbers

And finally, let's handle those phone numbers:

def list_available_numbers(area_code)
  get("/phone-numbers/available?areaCode=#{area_code}")
end

def purchase_number(phone_number)
  self.class.post('/phone-numbers', @options.merge(body: { phoneNumber: phone_number }))
end

Error Handling and Best Practices

Don't forget to add some error handling to your methods:

def get(endpoint)
  response = self.class.get(endpoint, @options)
  handle_response(response)
end

def handle_response(response)
  case response.code
  when 200..299
    response
  when 429
    raise "Rate limit exceeded. Try again in #{response.headers['Retry-After']} seconds."
  else
    raise "API error: #{response.code} - #{response.message}"
  end
end

Testing the Integration

Here's a quick example of how you might test your integration:

require 'minitest/autorun'
require_relative 'openphone_client'

class OpenPhoneClientTest < Minitest::Test
  def setup
    @client = OpenPhoneClient.new('test_api_key')
  end

  def test_get_contacts
    # Mock the API response
    HTTParty.stub :get, { 'contacts' => [] } do
      response = @client.get('/contacts')
      assert_equal [], response['contacts']
    end
  end
end

Deployment Considerations

When deploying, remember to:

• Store your API key securely (use environment variables!)
• Implement proper error logging
• Consider using a job queue for long-running operations

Conclusion

And there you have it! You've just built a solid foundation for your OpenPhone API integration. Remember, this is just the beginning - there's so much more you can do with the OpenPhone API. Keep exploring, keep building, and most importantly, keep having fun with it!
