Ecwid webhooks are automatic real-time notifications for apps about different events in the store. Webhooks are always sent as POST requests from Ecwid API to your server when something happens in a store, allowing you to automate practically any business process.
To receive webhooks, you need a self-hosted endpoint working on your side called webhookUrl:
Webhooks must be delivered as quickly as possible, so they only carry essential data about the event, for example, event details, store and item ID, timestamp, etc.
When you receive a webhook from Ecwid API, you must send back a confirmation to stop Ecwid API from sending it again.
