Environment Variables & Secrets in Workers
Configure your Cloudflare Worker with environment variables and securely manage secrets like API keys.

Hardcoding values like API keys into your Worker is insecure and inflexible. Environment variables and secrets keep config out of your code.
Vars vs Secrets
Workers distinguish two kinds:
- Vars: plain text config, visible in dashboard
- Secrets: encrypted, write-only values like keys and tokens
