# AWS API Gateway
We can use Gateway as the front-door to our application. It will create an [HTTP](/Databases/REST/HTTP_request_types.md) endpoint that you can call from a client. In response to a client request you can then call a [lambda function](/DevOps/AWS/AWS_Lambda/Lambda_handler_function.md) that executes a backend process.

See [using API Gateway as Lambda trigger](/DevOps/AWS/AWS_Lambda/Practical_walkthrough_Lambda_creation.md) for a basic example of usage.
