API Security Best Practices
Learn API security best practices including authentication methods, authorization strategies, and protection against common attacks.
Secure your APIs with proper authentication (API keys, JWT, OAuth 2.0), authorization (RBAC, scopes), and protection against common attacks. Use HTTPS everywhere, implement rate limiting to prevent abuse, validate all input to prevent injection attacks, use CORS headers properly, and set security headers like Content-Security-Policy and Strict-Transport-Security. See our <a href="/http-header/authorization">Authorization header guide</a> and <a href="/http-header/cors">CORS guide</a>.
