API Gateway documentation
API Gateway enables you to provide secure access to your backend services through a well-defined
REST API that is consistent across all of your services, regardless of the service implementation.
Clients consume your REST APIS to implement standalone apps for a mobile device or tablet, through
apps running in a browser, or through any other type of app that can make a request to an HTTP
endpoint. Learn more
