Explore what a restful API is, including resources, representations, and operations, and learn industry best practices for design, versioning, authentication, error handling, pagination, and formats like JSON and XML.
Explore representational state transfer concepts, including client–server exchanges, resources, request parts, response parts, and the main HTTP methods GET, POST, PUT, PATCH, and DELETE.
Explore REST operations like GET, POST, PUT, PATCH, DELETE, and OPTIONS, and how they manage resources safely, including status codes from 200 to 500 and the nouns over verbs principle.
Learn how REST emphasizes nouns over verbs and apply HTTP methods to perform create, read, update, and delete operations on resources like orders.
Compare json and xml formats for restful APIs, weighing serialization, schema support, tooling, and readability. Conclude that json is winning in APIs due to ease of client interaction and readability.
Versioning explains why API changes require clear versioning and compares root URL versioning (/v-1/orders) with query parameter versioning, recommending at least two stable versions.
Learn why robust error handling matters for RESTful APIs, implement consistent HTTP status codes with meaningful messages, codified errors, and documentation links to guide clients when something goes wrong.
Learn to use query parameters to power search and filtering in RESTful APIs, choose between query parameters and request bodies, and keep your API intuitive.
Explore how pagination and partial responses optimize restful APIs by using offset and limit, returning total records, and exposing only requested fields like IDs.
RESTful APIs are part of our everyday life and most may not even know it. Because most of the design and implementation of these APIs is left up to developers and architects, there are a wide array of opinions and ideas on how things should work. This can create a good deal of confusion.
Writing Beautiful RESTful APIs provides a fundamental overview of REST, best practices for design, and discusses several advanced topics like pagination, search, and authentication.
This course is meant for beginners to API design, but it is also a good refresher for those who are familiar to API design or are hoping to gain a deeper understanding of advanced topics.
By the end of the course, you will understand the fundamentals of REST and you'll be able to start designing your APIs to be "beautiful APIs".
