Update Subscriber’s External ID

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

Subscriber’s External ID is an attribute which is not versioned in the OCS.io. This means, that after this operation comes into effect, CRM will no longer be able to manipulate with the Subscriber using the old External ID. It is responsibility of the CRM system to version Subscribers' External IDs internally.
