Create response from JSON
Create Endpoints/Units/UnitResponse.php beside the endpoint. Extend
AbstractJsonResponse and keep constructor arguments named $response and
$body, typed as PSR ResponseInterface and GetValue.
Call the parent constructor, then use required getters to initialize typed
response fields. The response guide
contains a complete UnitResponse example.
Return UnitResponse from your endpoint operation and pass
responseClass: UnitResponse::class to the request helper. The SDK parses JSON
and constructs the response. Add tests for valid fields and invalid input.
