Looking to understand how the token value is generated in the following SSO call as it appears to change each time it is called :

web_submit_data("sso",
"Action=https://omc.openspan.com/tenantname/sso",
"Method=POST",
"TargetFrame=", "RecContentType=application/json",
"Referer=", "Snapshot=t2.inf",
"Mode=HTML",ITEMDATA,
"Name=token", "Value="long string of characters and numbers", ENDITEM, LAST);

We are trying to automate running our robots with Performance Center (vugen tool).
