As software systems become increasingly modular, robust APIs are critical for ensuring seamless data flow across platforms.

RESTful vs GraphQL

Understand the trade-offs. REST is standard and cacheable, while GraphQL allows clients to request exactly the data they need, reducing over-fetching.

Authentication and Security

Implement strict OAuth 2.0 or JWT authentication. Always validate and sanitize inputs to prevent injection attacks.

Rate Limiting and Caching

Protect your API from abuse by implementing rate limiting and leverage caching layers like Redis to handle high traffic loads efficiently.
