APIs are the hidden backbone of the modern web. Each time you check social media, APIs are likely calling several API endpoints behind the scenes.

HTTP APIs continue to be the most popular paradigm for creating data services. REST provides a elegant set of conventions for building endpoints that use web standards like the standard HTTP verbs to handle CRUD operations.

Protecting API endpoints is non-negotiable in today's development. Identity verification systems such as JWT tokens ensure verify that only authenticated users and applications can call your endpoints.

Managing API versions is another aspect in API design. When your service matures, teams will eventually need to make changes that might disrupt production integrations. Good versioning strategies allow preserve backward compatibility.

Good docs is often considered an lower priority in engineering work but is truly among the most essential aspects in API success. Properly documented interfaces minimize integration time, increase developer satisfaction, and decrease support requests.
