Core Mindsets for Web API Developers

1. "API-First" Mindset

Design the API as a product. Always think about the user (client) first. The API contract must be clear, consistent, and easy to use.

2. Stateless is King

Each API request must be independent and contain enough information to be processed. This is the foundation for building highly scalable systems.

3. Security is Not an Option

Build security in from the start, not as an add-on feature. Think about authentication, authorization, and input validation at every endpoint.

4. Architect for Sustainability

Use design patterns (like Repository, DI) and clean architecture to build APIs that are easy to maintain, test, and evolve in the future.
