Not sure if i worded that right but i was wondering if there was any new way to generate licenses for my scripts via api, also instead of user/password, i wanted to know if i could just generate one string key to keep it more simple.
Try printing ( with log) the command you are trying to execute, run it in a seperate command line to see if it's working properly.
since it's related to input I am suspecting the problem is with the youtube url you are providing
