API Design Guide
Published on 2017-02-21. Changelog
Introduction
This is a general design guide for networked APIs. It has been used inside Google since 2014 and is the guide that Google follows when designing Cloud APIs and other Google APIs. This design guide is shared here to inform outside developers and to make it easier for us all to work together.
Cloud Endpoints developers may find this guide particularly useful when designing gRPC APIs, and we strongly recommend such developers use these design principles. However, we don't mandate its use. You can use Cloud Endpoints and gRPC without following the guide.
This guide applies to both REST APIs and RPC APIs, with specific focus on gRPC APIs. gRPC APIs use Protocol Buffers to define their API surface and API Service Configuration to configure their API services, including HTTP mapping, logging, and monitoring. HTTP mapping features are used by Google APIs and Cloud Endpoints gRPC APIs for JSON/HTTP to Protocol Buffers/RPC transcoding.
This guide is a living document and additions to it will be made over time as new style and design patterns are adopted and approved. In that spirit, it is never going to be complete and there will always be ample room for the art and craft of API design.
