Webhooks vs polling, which is better?

Webhooks are almost always better: the source system pushes an event the instant something changes, so data stays fresh and you don’t hammer the API. Polling is the fallback when a third-party platform doesn’t emit webhooks, we then poll on a sensible schedule with a cursor so we only fetch what changed. For high-volume two-way flows we layer RabbitMQ queues on top so neither side is overwhelmed.
