Stripe Subscriptions in Rails

Choosing the right payment solution for your app could be tricky, especially if you're running a global marketplace. The prospect of dealing with country-specific regulations is not something I look forward to while getting on a new project. Also, there is a lot of boilerplate that you have to handle to get recurring billing to work. Stripe seems to understand the pain thousands of developers face every day and solves it pretty well. In this article, I will demonstrate how to integrate Stripe into your Rails app. Read on.

Setting Up

Before we begin, you will need a Stripe API key. You can obtain one by signing up with Stripe with your bank details. There are two different set of keys, one for your test and one for production.

Let's begin by setting up the Stripe client. Add this to your Gemfile:

[ruby] gem 'stripe', :git => 'http://ift.tt/1lJK0yH' [/ruby]

and bundle install.

Once you are done installing your dependencies, you need to setup your API keys. In production, you would store these keys in an environment variable and take it out of the codebase. But for brevity's sake, I'm going to set them in an initializer. Kindly refrain from throwing pitchforks at me... :)

[ruby] # config/initializers/stripe.rb #todo remove the key info from this file and have env variable #todo recreate new API keys when do that if Rails.env == 'production' Rails.configuration.stripe = { :publishable_key => MY_PUBLISHABLE_KEY, :secret_key => MY_SECRET_KEY } else Rails.configuration.stripe = { :publishable_key => TEST_MY_PUBLISHABLE_KEY, :secret_key => TEST_MY_SECRET_KEY } end Stripe.api_key = Rails.configuration.stripe[:secret_key] [/ruby]

With that out of the way, let's setup our payment page.
