What We Cover in Backend & APIs

🌐

REST & HTTP

Methods, status codes, request/response cycle — what actually happens when AI calls an API.

🔑

Authentication

JWT, OAuth, sessions, API keys — keeping the right people in and the wrong people out.

🪝

Webhooks

Real-time notifications, event-driven architecture — making apps react to the outside world.

🚦

CORS & Rate Limiting

Why your API calls get blocked and how to fix the most frustrating errors in development.

📊

GraphQL

Queries, mutations, schemas — an alternative to REST that AI is increasingly choosing.

⚡

WebSockets

Real-time bidirectional communication — how chat apps and live dashboards actually work.
