Implementing a stand-alone curl command

I guess I'm mixing the two. I went to the subscribe web page form just so I can look at the syntax and the available options for the curl command. 

I want to use a simple curl.exe command from windows command prompt, that I can call from VFP program after. That part works.
What would be the part after [admin/?page=] in [https://hepsales.hosted.phplist.com/lists/admin/?page=importsimple] if I want to confirmation email to be sent?
What do I replace “importsimple” with if I just want to subscribe just one email address from curl?


curl -v --insecure -F login=email1@hepsales.com -F password=xxxxxxxxxxx -F importcontent=myemail@abc.com -F importlists[2]=2 -F notify=no -F makeconfirmed=0 -F htmlemail=1 -F import=import https://hepsales.hosted.phplist.com/lists/admin/?page=importsimple

works but doesn’t send them confirmation email.

I guess my question is, where do I find what options are available to me after 

… [admin/?page=] ?

or what comes after " ..../lists/?page= "
in case someone else needs it, in the importsimple the parameter is [ -F confirm=1 ], not [ -F makeconfirmed=1 ]. I just needed to find the importsimple.php page in order to finalize adding a subscriber with curl.exe only, from windows/dos. Works like a charm now. 

Duncan, thanks for your help on this!
