This project is for you, if you want to learn how to develop a public-facing (or private) API, using Ruby on Rails. We'll learn about how to secure your application, making it user-based and token-based authentication so you have the ultimate choice in how you want to structure your own app. If you're curious about the advantages of building an API with Rails, check out this page:



This Ruby on Rails tutorial will cover all the details (resources, tools, languages etc) that are necessary to build a complete and operational external API. You will be guided through all the steps and concepts, starting from the basic ones like setting up the right tools and frameworks to the more advanced topics related to the development. Ultimately I should help you master creating your own API’s and get building soon enough, without any difficulty.
