https://docs.mulesoft.com/api-manager/2.x/tutorial-manage-an-api Steps are as below :
Add the Required RAML Snippet

SLA-based rate limiting requires adding a RAML or OAS snippet to your API. This procedure demonstrates adding a RAML snippet.
Specify the client ID and secret as query parameters.
Add a section called traits: at the RAML root level to define query parameters:
traits:
- client-id-required:
queryParameters:
client_id:
type: string client_secret:
type: string
Add the client-id-required trait to every method that requires these query parameters:

/users:
get:
is: [client-id-required]
description: Gets a list of JSONPlaceholder users.

DataWeave Function Definition Syntax
To define a function in DataWeave use the following syntax:
fun myFunction(param1, param2, ...) = <code to execute> The fun keyword starts the definition of a function.
myFunction is the name you define for the function.
Function names must be valid identifiers.
(param1, param2, ... , paramn) represents the parameters that your function accepts. You can specify from zero to any number of parameters, separated by commas (,) and enclosed in parentheses.
The = sign marks the beginning of the code block to execute when the function is called. <code to execute> represents the actual code that you define for your function.
