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

Introduction

Hey there, fellow developer! Ready to supercharge your Ruby project with respond.io's powerful API? You're in the right place. This guide will walk you through creating a sleek, efficient integration that'll have you managing conversations and contacts like a pro in no time.

Prerequisites

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

• Ruby 2.7+ installed
• The httparty gem (we'll use this for API requests)
• Your respond.io API credentials (if you don't have these yet, hop over to the respond.io dashboard and grab 'em)

Setting up the project

Let's get this show on the road:

mkdir respond_io_integration
cd respond_io_integration
bundle init

Now, open up your Gemfile and add:

gem 'httparty'

Run bundle install, and we're off to the races!

Authentication

First things first, let's set up authentication:

require 'httparty'

class RespondIoClient
  include HTTParty
  base_uri 'https://api.respond.io/v1'

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

Making API requests

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

def get_contacts
  self.class.get('/contacts', @options)
end

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

Implementing key features

Let's put these methods to work:

client = RespondIoClient.new('your_api_key_here')

# Get contacts
contacts = client.get_contacts
puts contacts

# Send a message
response = client.send_message('contact_123', 'Hello from Ruby!')
puts response

Error handling

Always be prepared! Let's add some error handling:

def send_message(contact_id, message)
  response = self.class.post('/messages', @options.merge(
    body: { contact_id: contact_id, message: message }.to_json
  ))
  
  case response.code
  when 200
    puts "Message sent successfully!"
  when 401
    puts "Unauthorized. Check your API key."
  else
    puts "Error: #{response.code} - #{response.message}"
  end
  
  response
end

Testing the integration

Don't forget to test! Here's a simple RSpec example:

RSpec.describe RespondIoClient do
  let(:client) { RespondIoClient.new('test_api_key') }

  it 'sends a message successfully' do
    VCR.use_cassette('send_message') do
      response = client.send_message('contact_123', 'Test message')
      expect(response.code).to eq(200)
    end
  end
end

Best practices

A few tips to keep in mind:

• Respect rate limits! Check the API docs for current limits.
• Keep your API key safe. Use environment variables, never commit it to version control.
• Consider implementing retries for failed requests.

Conclusion

And there you have it! You've just built a solid foundation for your respond.io API integration in Ruby. From here, you can expand on this base, adding more features and fine-tuning to your heart's content.

Remember, the best integrations are built iteratively. Start small, test often, and gradually add more complexity. You've got this!

Happy coding, and may your conversations always be engaging and your contacts always responsive!
