Webhooks
COPE webhooks deliver selected cart, checkout, order, payment, refund, chargeback, and payout events to subscriber endpoints as CloudEvents 1.0 structured JSON. Register HTTPS endpoints in the COPE dashboard. Use the event reference to choose the webhook types your integration is ready to process.Delivery semantics
