The message flow of business entities from Commerce Cloud to Order Management Cloud happens through the Oracle Integration Cloud Service.

Commerce Cloud includes a Commerce adapter on Oracle Integration Cloud Service infrastructure that is used for Integration. The Order Management Cloud part of the integration uses the generic SOAP adapter of the Integration Cloud Service to meet Integration purpose. The data from Commerce using the webhook framework goes through the Oracle Integration Cloud Service and reaches the Order Management Cloud. The data from the Order management reaches Commerce through the integration cloud service as well.

For more information about Oracle Integration Cloud Services, refer to the documentation on the Oracle website.
