The video tutorial covers fundamental principles of REST API development, explaining its architecture, constraints, and best practices. It discusses key concepts like uniformity, statelessness, and cacheability, and how REST APIs facilitate layered systems. The tutorial also delves into HTTP methods for CRUD operations and the importance of correct HTTP response codes.
