title: Is there a way to change the http status codes returned by Amazon API Gateway?
body: <p>For instance if I want to return a specific 400 error for invalid parameters or perhaps a 201 when the lambda function call resulted in a create.</p>
  
  <p>I'd like to have different http status codes but it looks like api gateway always returns a 200 status code even if the lambda function is returning an error.</p>
