Updates the customer object for the customer specified in the request body.
Special Notes
If changes are entered for any other fields, the system will ignore them and retain existing values.
You must include the entire set of Customer Object Attributes in your change request, even if you are changing just one of the fields. Failure to do this will result in any non-included fields being set to null.
If you know a field is set to null, and you want to keep it that way, you do not need to include it in the Request.
