# Architecting Bulletproof REST & GraphQL APIs
APIs serve as the foundational gateway for web apps, mobile apps, and partner integrations. A single security vulnerability or slow query can degrade your entire digital product.
Key Principles of CombineGrowth API Architecture 1. **OAuth2 & JWT Auth**: Fine-grained token scopes with short expiration and automatic refresh rotators. 2. **Redis Rate Limiting**: Token-bucket algorithm preventing DDoS and API quota abuse. 3. **OpenAPI / Swagger Generation**: Code-first schema generation ensuring client SDKs never go out of sync. 4. **Sub-50ms Caching**: Intelligent cache invalidation using Redis clusters.
