Olo Webhooks
Olo exposes outbound webhooks that fire on order lifecycle events (placed, confirmed, ready, completed, refunded), gift-card activity, loyalty accrual / redemption, tender events, and marketplace status changes. Webhooks are HMAC-signed; reference signature-validation samples are published in C#, Java, PHP, Ruby, JavaScript, and Python in the ololabs/dev-support-code-samples repository.
