How many methods can we apply under resource in raml?

In RAML, you can apply as many methods as you like under a single resource. However, there's an important caveat:

• Each HTTP method can only be used once per resource.

This means you can define various functionalities for a resource using different HTTP methods like GET, POST, PUT, DELETE, etc. But, you cannot have two methods with the same name (e.g., two GET methods) within the same resource.

Here's a breakdown:

• Scenario 1 (Valid):

YAML

/users:
  get:
    description: Retrieve a list of users
  post:
    description: Create a new user

In this example, the resource /users allows both GET and POST methods for different functionalities.

• Scenario 2 (Invalid):

YAML

/products:
  get:
    description: Retrieve a list of products
  get:  # This is not allowed
    description: Retrieve a specific product by ID

Here, having two GET methods within the same resource is not allowed.

Here are some alternative approaches to achieve the desired functionality:

• Use Path Parameters:

YAML

/products/{id}:
  get:
    description: Retrieve a specific product by ID

• Use Query Parameters:

YAML

/products:
  get:
    description: Retrieve a list of products
    queryParameters:
      id:  # Filter products based on ID
        type: string

By following these guidelines, you can effectively utilize multiple methods within a RAML resource while maintaining clarity and avoiding naming conflicts.
