Only provided fields are modified. All fields in the request body are optional — omit a field to leave it unchanged.
LMS internally requires firstname and lastname on every customer update even when neither is changing. The service reads the existing customer and fills these in transparently — true partial updates work as documented, no need to echo the name on every PUT.
Some fields (status, officeId, accountNo) are not updatable via this endpoint. Use Activate and Close for status transitions.
