title: Client TLS Authentication with AWS API Gateway
body: <p>Is it possible to set up client TLS authentication on AWS API Gateway?</p>
  
  <p>I do not mean between API Gateway and Elastic Beanstalk, as it is described <a href="https://docs.aws.amazon.com/apigateway/latest/developerguide/getting-started-client-side-ssl-authentication.html" rel="nofollow noreferrer">here</a>, but between the client and the API Gateway itself, probably having a custom authorizer (e.g. Lambda) that checks the certificate for validity before forwarding the request to Elastic Beanstalk.</p>
