[xwiki-users] Adding custom object using Xwiki REST service

Now I have more tricky question -- how to add custom object using Xwiki REST service. By browsing existing ones I assume, I can create linked custom object using POST before, and get object id. Then I add wiki document using PUT and set relation to previously created object. Is it right approach to test? Are there more recommendations beside http://platform.xwiki.org/xwiki/bin/view/Features/XWikiRESTfulAPI Thanks, Valdis
