I used a free, open sourced starter bootstrap template and modified the content as needed.

SAM makes it very easy to get started with creating Serverless apps and maintain them as they start getting more and more complex and involved. For more information on SAM , check this out - https://github.com/awslabs/serverless-application-model

However , AWS_IAM authorization is not supported in the implicit API declaration as detailed here :https://github.com/awslabs/serverless-application-model/issues/25
