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

Introduction

Hey there, fellow Ruby enthusiast! Ready to dive into the world of MemberPress API integration? You're in for a treat. We'll be building a sleek, efficient integration that'll have you managing members like a pro in no time. Let's get cracking!

Prerequisites

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

• Ruby 2.7+ (because who doesn't love the latest and greatest?)
• The httparty and dotenv gems (our trusty sidekicks)
• Your MemberPress API credentials (don't forget to keep these secret!)

Setting up the project

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

mkdir memberpress_integration
cd memberpress_integration
bundle init

Now, add these gems to your Gemfile:

gem 'httparty'
gem 'dotenv'

Run bundle install, and we're ready to rock!

Configuring the API client

Let's create a killer API client class:

require 'httparty'
require 'dotenv/load'

class MemberPressClient
  include HTTParty
  base_uri 'https://your-site.com/wp-json/mp/v1'

  def initialize
    @options = {
      headers: {
        'Authorization' => "Basic #{ENV['MEMBERPRESS_API_KEY']}"
      }
    }
  end

  # We'll add more methods here soon!
end

Implementing core API functionalities

Now for the fun part! Let's add some methods to our client:

class MemberPressClient
  # ... previous code ...

  def fetch_members
    self.class.get('/members', @options)
  end

  def create_member(data)
    self.class.post('/members', @options.merge(body: data))
  end

  def update_member(id, data)
    self.class.put("/members/#{id}", @options.merge(body: data))
  end

  def get_membership_levels
    self.class.get('/membership_levels', @options)
  end

  def check_subscription(member_id)
    self.class.get("/members/#{member_id}/subscriptions", @options)
  end
end

Error handling and rate limiting

Let's add some error handling magic:

def handle_response(response)
  case response.code
  when 200...300
    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

Wrap your API calls with this method, and you're golden!

Testing the integration

Time to put our code through its paces:

require 'minitest/autorun'

class TestMemberPressClient < Minitest::Test
  def setup
    @client = MemberPressClient.new
  end

  def test_fetch_members
    response = @client.fetch_members
    assert_equal 200, response.code
  end

  # Add more tests for other methods
end

Best practices and optimization

To keep things speedy, consider caching responses:

require 'redis'

def fetch_members
  cache = Redis.new
  cached_response = cache.get('members')

  if cached_response
    JSON.parse(cached_response)
  else
    response = self.class.get('/members', @options)
    cache.setex('members', 3600, response.body) # Cache for 1 hour
    response
  end
end

Extending the integration

Feel like a superhero yet? Let's add a custom endpoint:

def custom_endpoint(path, method = :get, data = nil)
  options = @options
  options = options.merge(body: data) if data

  response = self.class.send(method, "/#{path}", options)
  handle_response(response)
end

Conclusion

And there you have it! You've just built a robust MemberPress API integration in Ruby. Pat yourself on the back, you coding wizard! Remember, the API is your oyster - keep exploring and building awesome things.
