## one-gateway-to-every-api

One Gateway to Every API The API Gateway provides a unified entry point for all DXP APIs and external service integrations. Rate limiting protects backends from overload. Authentication supports OAuth2, JWT, and API key with granular scope-based permissions. Request transformation modifies inbound requests before they reach backends — header injection, path rewriting, body transformation. Response caching reduces backend load for frequently-accessed data. Real-time monitoring dashboards show latency, error rates, and throughput.
