How to launch a new request with context parameters from an external application via a URL

Hello,

can you please give another syntax example for
http://[myserver]/wfgen/show.aspx?QUERY=PROCESS_START_REMOTE

I tried:
http://workflow/wfgen/show.aspx?QUERY=PROCESS_START_REMOTE&PROCESS="SDK_CS_REMOTE_LAUNCH"&TEST="Y"
(–> using the example given)

I am getting the following error notification:
“The process ‘“SDK_CS_REMOTE_LAUNCH”’ cannot be found”.
(–> I tried with several other processes as well)

Am I missing something? Is the syntax incorrect?
How can I call the right process?

Thank you,
regards
