GetClients API custom fields search
We are integrating WHMCS with another system(REGY) that we have, and we have a problem mapping the users.
I am storing the using the REGY ID of the user in the customfields field, available on WHMCS's AddClient API call.
I cannot search for that REGY ID using API GetClients, on the documentation it says it will only search on "email, firstname, lastname, fullname or companyname".
My Request is, please add the ability to search in custom fields in the GetClients API, it would be very useful. There is a similar request here: http://requests.whmcs.com/topic/client-custom-field-search
Thanks in Advance
