How should I call SAM on port 1221 directly?
I tried in this way but unsuccessfully

http://MYIP:1221?songID=10189


P.S. "MYIP" is put just for privacy. In the reality there is the IP of SAM Server

Depends on what you want to query?
SAM does at least two (probably there are more options I just forgot about) things on Port 1221, so you will need to differentiate the URL.
/event is for PAL event hooks
/req is for requests

This is how the URL format looks in the code.request.php:

So the /req/ endpoint expects 2 parameters: songID and host
songID should be an integer and host is either an IP or a hostname in URLencoded foprmat.

Your URL should look like this:
http://MYIP:1221/req/?songID=10189&host ... stname.com

Excellent, I did try it and it works.
The important is that the calling IP (the one of the server that calls) is into
Config > Request Policy > Only accept requests from these IP addresses

Thanks a million

But make sure to also include the hostname/IP of whoever you're making the request for. Or disable the "The same viewer can vote [aa] times every [bb] minutes, but no more than [cc] times per day." rule in your request policy.
