When I do the following: api?command=listTemplates&templatefilter=featured&apikey=******&response=json
The result is the following (I have tried the API key of a domain admin and root admin, as well as a cookie session after GUI login - all yielded same result): { "listtemplatesresponse" : {"uuidList":[],"errorcode":401,"errortext":"unable to verify user credentials and/or request signature"} } Per this forum post, there was a suggestion to change the case of the commands - that changed the output, but still didn't work: api?command=listtemplates&templatefilter=featured&apikey=******&response=json { "errorresponse" : {"uuidList":[],"errorcode":432,"errortext":"The given command does not exist"} }
