I have used the whmcs api to create a new client when we create a new client in sugar crm. I would like to be able to create additional contacts for that created client through the api and I do not see that listed in the api functions. Also it would be nice if there was a way to update custom client fields from the api also. That way I could store the sugar crm client id in whmcs when a new client is created through the whmcs api.
