Real-Time vs. Batch Processing

When should you use polling (interval) triggers vs. webhooks in n8n for syncing data with external APIs? Provide a use case where a combination of both is required?

if an external service supports webhooks, then it’s a preferable way, as it’s possible to receive events in real-time.

Polling is a general way to access data via API.

But generally, it depends on what you are trying to achieve.
