Update Customer’s Segment

The CRM / Ordering system updates a Customer in the OCS.io via the RESTful API. The request body contains updated Customer details like External ID, Custom Name, etc. The OCS.io updates the instance of the Customer, then returns Business Transaction containing updated Customer as a payload of the response. Other systems may be notified about the Business Transaction via the Streaming Platform.

While a history is maintained for the Customer Segment attribute in OCS.io, the new value becomes effective immediately and is used in subsequent processes like rating & charging, billing & invoicing. Please note that historical values are not considered in these processes.
