Updates a Cartʼs customer_id.

Notes

Changing the Cart customer_id will remove any promotions or shipping calculations on the Cart. These are tied to the customer depending on cart conditions and any customer groups.

To prevent lost updates due to concurrent requests overriding changes made by others, it is recommended to enable optimistic concurrency control by including the version field in the request payload. If the provided version does not match the version on the server, a conflict error will be returned, which the client can handle accordingly.
