title: How to point ApiGateway to a specific Lambda alias
body: <p>I created a resource in Amazon's ApiGateway.  It is pointing to a Lambda function.  This is being hit by a native mobile application (android and ios) which is already in the wild.</p>
  
  <p>I now want to modify the Lambda function, but I see no way to change my ApiGateway resource to point to an alias of the lambda.  This is my first time playing with any of these technologies and I see no easy mechanism to manage this in the aws console.</p>
  
  <p><strong>How can I modify my ApiGateway resource to point to my lambda alias so I can edit trunk without affecting existing clients?</strong></p>
