Reduce API latency by implementing HTTP caching headers like Cache-Control and ETag to serve 304 responses, applying gzip or brotli compression, and minimizing payload sizes. You can further reduce response times through database query tuning and adding monitoring alerts.

Minimize API payload size by applying sparse fieldsets to return only requested data, removing sensitive or unused fields from JSON responses, and enabling compression. This reduces bandwidth consumption and improves overall application performance.

HTTP caching for REST and GraphQL endpoints works by setting Cache-Control, ETag, and Last-Modified headers. This enables clients to validate cached responses and receive 304 Not Modified status codes, avoiding redundant data processing and reducing server load.

Yes, you can use gzip and brotli compression to speed up slow API responses. Compressing JSON payloads before transmission significantly reduces bandwidth usage and decreases the time required to transfer data to the client.

Add monitoring and alerts to your API optimization strategy when backend services experience high traffic or slow responses. Monitoring tracks the performance impact of caching, compression, and query tuning, alerting you to latency regressions.

Yes, API response optimization works for both REST and GraphQL endpoints. The strategies apply universally, including HTTP caching headers for REST, fragment caching for GraphQL, payload minimization, and query optimization to improve backend service performance.
