AWS Serverless REST API

This project uses Terraform to configure and deploy a REST API using AWS Gateway and AWS Lambda to serve the endpoints.

The lambda handlers are defined in lambda/handlers/http_methods.py, these methods correspond to the methods associated with the methods on the API resources. Below is a table with the endpoints and associated lambda functions, skeleton methods are defined in /lambda/handlers/http_methods.py with no implementation.

The response from the lambda method should use the format provided by Response.format class method.

ROUTE	METHOD	HANDLER
/resource	GET	http_methods.list
/resource	POST	http_methods.post
/resource/<string:post_id>	GET	http_methods.get
/resource/<string:post_id>	PUT	http_methods.put
/resource/<string:post_id>	DELETE	http_methods.delete
