There are a number of webhooks within Commerce Cloud that provide support for configured items. The webhooks that support configuration are:
Approval
Cart Idle
External Price Validation
Order Submit
Order Submit for PCI Compliant Target Systems
Quote Request
Quote Update
Return Request Update
You must ensure that each of these webhooks is configured to work with your external configurator. This means providing appropriate URLs, usernames, and passwords to each of these webhooks. See Configure webhooks for more information.
