What Is RAML?

RAML stands for RESTful API Modeling Language. RAML is generally used to design APIs to consume a web service. Designing an API is easy, but designing an API that is long-lived, and that your users love - well, that's a little bit harder. But with RAML, you are able to take advantage of the full API Design Lifecycle, and that means you can design your API visually, test it, and get user feedback without ever having to write a single line of code.

Designing an API

1. Go to the Anypoint site and signup for an account.

6. You will be redirected to your RAML File.Image title

With this, you can start writing in your RAML file and see the beauty it creates.

Writing Queries in a RAML File

Writing queries in a RAML file include some important methods, which are described as follow:

  1. GET - Retrieve the information defined in the request URI

  2. PUT - Replace the addressed collection. At the object-level, create or update it

  3. POST - Create a new entry in the collection. This method is generally not used at the object-level.

  4. DELETE - Delete the information defined in the request URI.

We can use as many methods as much as we want in our API.

How to Write Queries

Writing a query in RAML is very easy. The following is a snippet of queries and the way it should be written.

Queries for POST, PUT, and DELETE can also be written in the same way (the response for POST is 201).
