Hi,
Our project requests to handle 'cis_registered' field from api request
[Contracts] has "cis_registered" field. https://developer.sage.com/accounting/reference/contacts/#tag/Contacts/operation/postContacts
We can read 'cis_registered' field from api request.
But It's not support changing 'cis_registered' call by api(post/put) requests.
Can you support updating 'cis_registered' field by sage accounting api.
Sincerely,
