# 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_within_AWS.md)
for a basic example of usage.
