The two answers are polling and webhooks. Polling asks the question repeatedly. Webhooks get notified when the answer changes. Understanding which approach fits a given situation — and why — shapes everything from latency and cost to reliability and operational complexity.</p> <h2 id="polling-the-default-that-mostly-works">Polling: The Default That Mostly Works</h2> <p>Polling is the simpler mental model. Your application sends requests to an API on a schedule — every 30 seconds, every minute, every hour — and checks whether anything has changed since the last check. If yes, process the changes. If no, wait for the next interval.</p>
