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.

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.

Lambda Proxy Integration is allowed now, and because of that the Lambda function can return proper HTTP codes and headers:

let response = {

    statusCode: '400',

    body: JSON.stringify({ error: 'What up!' }),

    headers: {

        'Content-Type': 'application/json',




The second option is to integrate aws-serverless-express with an already existing Express app with Lambda/API gateway.
