MuleSoft Doc Ref : 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]

QUESTIONNO: 96

Refer to the exhibits.

The main flow contains a Flow Reference to the child flow.

A web client sends a GET request to the main flow's HTTP Listener that includes a make query parameter.

What values are accessible in the child flow?

A. payload

B.payload

make query param

C. payload

model var

D. payload

make query param model var

Answer: D

Correct answer is String is not blank.

-------------------------------------------------------------------------------------------------------------------------------------------------

Here’s specifically what is happening here:

1) Payload is successfully set to “Start”

2) The Is Blank String validator createsan Error Object because the payload is string "Start". Execution stops

#[error.description] = “String is not blank”

3) Because no error handler is defined, the Mule default error handler handles the error. Remember, at its heart, the Mule Default Error handler is an error handling scope with just an on error propagate

4) “String is not blank” is the error message returned to the requestor in the body of the HTTP requestHTTP Status Code: 500
