I am using SugarCRM v11_4 REST API (which is SugarCRM version 8.3). I believe it only supports Sugar cloud versions. I need to know which version of SugarCRM it supports. Does it only support REST API v10 and above (SugarCRM v7.7.x and above)?
SugarCRM 6.5 seems to be REST API v4.1. Would v11_4 API work with that?
