Possible to issue software serial on Paid Subscription?

[MagicPID]

Hello,

I operate a site where my forum is a part of a two part package - the second part being a software utility. I use an online licensing system where a simple POST command will generate a license for my software and return a serial number for it.

Is it possible for vBulletin (through some feature I'm unaware of, or an add-on) to send the command to my license API this each time someone purchases a certain Paid Subscription and give the user the generated license key?

Thanks so much for your help. If I'm able to automate this process, I'll end up saving so much time!
