💡 Webhooks vs. Polling

Factor	Webhooks	Polling
Latency	Real-time (seconds)	Depends on poll frequency
Infrastructure	Requires public HTTPS endpoint	Outbound requests only
Firewall	Needs inbound access	Firewall-friendly
Best for	Real-time sync	Batch processing, restricted networks

Most integrations use webhooks for real-time updates. Use polling if your infrastructure doesn't support inbound connections.
