Frequently asked questions
Quick answers about this topic hub.
What is the difference between REST and GraphQL?▾
REST exposes multiple endpoints that each return fixed data shapes, while GraphQL exposes a single endpoint where clients request exactly the fields they need. REST is simpler and cache-friendly; GraphQL reduces over-fetching for complex, nested data.
How should I secure an API?▾
Use HTTPS everywhere, authenticate requests (API keys, OAuth, or JWTs), authorize on the server for every request, validate all input, and rate-limit to prevent abuse. Never trust the client.
What makes good API documentation?▾
Clear endpoint descriptions, request/response examples, authentication steps, and error explanations. Tools like the OpenAPI (Swagger) spec let you generate interactive docs from a single source of truth.
