# Webhooks

eInvoicing can notify your backend about invoice status changes in real time, instead of you having to poll [List Invoices](/chekin-public-api/api-reference/einvoicing/invoices/list-invoices.md).

* [Invoice webhooks](/chekin-public-api/api-reference/einvoicing/webhooks/invoice-webhooks.md) — configure `webhook_configurations` on a supplier and track invoice status changes.
