Configure the webhooks you intend to use. At a minimum, you will need to configure the Order Submit webhook. If your store includes the Agent Console, you should also configure the Return Request Update webhook.

To configure a webhook, you supply the URL to direct POST requests to, the headers to include, and authentication information. The values to supply are determined by your OMS. See Configure webhooks for more information.

Register your OMS application with Oracle Commerce Cloud Service. Doing this generates an application ID and an application key that the OMS can use for authentication when it makes REST calls to Oracle Commerce Cloud Service. See Register applications for more information.
