Question

A company is using Amazon API Gateway to develop an API for its application on AWS. A developer needs to test and generate API responses. Other teams are required to test the API immediately. What should the developer do to meet these requirements?

Why each option

API Gateway mock integrations let developers generate synthetic responses without a backend, enabling immediate testing by all teams.

ASet up a mock integration request in API Gateway. Configure the method's integration requestCorrect

A mock integration in API Gateway allows the developer to define static responses directly in the method's integration request without any backend service. This means all teams can call the endpoint and receive configured responses immediately, making it ideal for early-stage API testing and parallel team development.

BSet up the request validators in the API's OpenAPI definition file. Import the OpenAPI definitions

Request validators in an OpenAPI definition enforce input validation but do not generate or return mock responses for testing.

CSet up a gateway response for the API in API Gateway. Configure response headers with

Gateway responses customize error responses (4xx/5xx) returned by API Gateway itself, not simulated backend responses for functional testing.

DSet up a request parameter-based Lambda authorizer to control access to the API. Configure the

A Lambda authorizer controls access to the API based on a token or request parameter but does not generate test responses.
