Webhooks for order and vehicle revisions allow getting notifications when an order or its vehicles are updated. Using these webhook events API users are able to fully synchronize data in their system with Shipper TMS. These events allow subscribing to any subset of field changes. For example, if you are interested only in price changes you can subscribe to the price field changes and get notified only when the order price is changed.

Please, see details in the Webhooks for order and vehicle revisions section of documentation and in API Reference.
