In today's connected world, APIs are the backbone of software. This course provides a fundamental understanding of what web services and APIs are and how they work. We cover the core architectural styles that dominate modern development: REST and GraphQL.
You will learn the principles of REST, including resources, HTTP verbs, and statelessness. We'll explore the structure of a GraphQL query and understand why it's a powerful alternative to REST. The course also covers common data formats like JSON, and essential authentication strategies used to secure APIs, such as API Keys and JWT.
This course is for aspiring front-end and back-end developers, project managers, and anyone who needs to understand how modern applications communicate.
