Key takeawaysREST polling: ask the API every 1-5 min „anything new?” → 12-60 useless calls/hourWebhook: notified in under 1 sec on change → 0 useless calls, minimal latency Definition A webhook (or „HTTP callback”) is the mechanism by which a system automatically sends an HTTP POST to a pre-configured URL when an event happens (new order, invoice issued, delivery confirmed). Why it beats polling REST polling: ask the API every 1-5 min „anything new?” → 12-60 useless calls/hour Webhook: notified in under 1 sec on change → 0 useless calls, minimal latency Azuvio events exposed as webhooks order.created / order.shipped / order.delivered invoice.issued / invoice.paid inventory.low_stock / inventory.reserved partner.created / partner.updated chargeback.received Webhook receiver best practices Respond HTTP 200 fast (under 5 sec), process async Validate signature (HMAC) for security Idempotency: the same event may be delivered multiple times Frequently askedWhat if my URL is down?Azuvio retries with exponential backoff (5 min, 30 min, 2h, 12h, 24h).
