EnvStore supports two authentication methods for accessing API endpoints:
- Usage: Web interface and browser-based requests
- Method: HTTP-only session cookies
- Security: CSRF protection with double-submit cookies
- Rate Limiting: 5 login attempts per 15 minutes per IP
- Usage: Programmatic access and server-to-server communication
- Header:
x-api-key: esk_live_your-api-key - Format:
esk_live_prefix followed by 32-character token - Rate Limiting: Higher limits for authenticated requests (60/min vs 20/min)
