Salla Webhooks
Server-to-server event delivery covering order, product, customer, shipping, shipment, store branch, category, brand, abandoned cart, coupon, invoice, special offer, and review lifecycle events. Payloads are signed via HMAC SHA-256 — X-Salla-Security-Strategy and X-Salla-Signature headers (or token strategy with Authorization header) — and developers can attach conditional rules per subscription.
