RESTful API Design Principles

Welcome! In this lesson, we'll explore RESTful API design principles. REST stands for REpresentational State Transfer, a set of architectural principles for designing networked applications.

For a SaaS product, a well-designed RESTful API is crucial for:

• Scalability: Handling many users and requests.
• Maintainability: Easy to understand and update.
• Interoperability: Works well with different clients (web, mobile).

The core idea of REST is to focus on resources. Think of resources as the 'nouns' of your application, like users, products, orders, or subscriptions.

Instead of thinking about actions (e.g., getUser, createProduct), think about the data itself. Each resource should have a unique identifier.

• Good: /users, /products
• Avoid: /getAllUsers, /createProduct
