# API Gateway documentation

[Read product documentation](https://docs.cloud.google.com/api-gateway/docs/about-api-gateway)
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.
