Before we look at creating resources, it’s important to understand that authentication and validation are extremely important on the backend. Real APIs must:
- Validate all incoming data thoroughly
- Authenticate users properly
- Authorize actions based on user permissions
In this lesson, we’ll use only basic validation (checking if fields exist) and simple authentication patterns to focus on learning CRUD operations. These are not production-ready security measures.
In Module 3, you’ll learn proper validation and authentication. For now, we’re building the foundation.
