so I installed the ISPCFG3 WHMCS module from Git, but the manual doesn't mention what permissions should I grant the Remote User ? Client Functions and what else ?
I am about to do this, however, i imagine it should be the permissions as outlined by whmcs themselves? You would need a whmcs user on the server it is going to be controlling with appropriate permissions according to whmcs. I will be doing this later today...will post back if i find anything different from what i have said above.
