Web Hosting Provider: How to link OnlyOffice workspace to WHMCS?

We are a web hosting provider using whmcs. We installed Onlyoffice WORKGROUP. Is it possible to add multiple domains and create users (mailboxes) with each of the domain name? Is it possible to define a disk quota per user mailboxes ? possible to disable sending mail features per mailbox?
Possible to get an API which will allow us to link to whmcs?

We are looking for this solution :
