[+] PRODUCTION BEST PRACTICES

1. Rate Limiting: Always implement exponential backoff when polling third-party webhooks or CRM endpoints.
2. Data Hygiene: Validate email syntax using regex before initiating REST calls to keep API costs minimal.
3. Secrets Management: Never hardcode access tokens; load credentials dynamically via environment variables (`.env`).
