APIs are at the center of modern digital systems. They connect applications, cloud platforms, partners, mobile apps, microservices, and enterprise backends. Designing APIs properly requires more than exposing an endpoint. You need to understand API design principles, REST conventions, OpenAPI specifications, payload formats, backend patterns, and how these concepts are implemented inside an API management platform such as Google Cloud Apigee X.
This course, API Design with Apigee X: REST, OpenAPI, GraphQL, focuses on the practical API design and development layer of Apigee X. You will begin with RESTful API design principles and best practices, including HTTP methods, status codes, resource-oriented thinking, URI design, and API behavior patterns. You will then take a deeper look at OpenAPI specifications and how they help document, standardize, and support API proxy development.
The course also introduces GraphQL and gRPC from an enterprise API management perspective. You will learn how these API styles differ from traditional REST APIs and where they may fit in modern architecture. You will also explore JSON and XML payload handling, which remains important in real-world enterprise integration scenarios.
