suppose I bought a key for fingerprint switcher, made a bot and sold it. will i have to renew it every time periodically to keep the bot working. Or the bot i made will work if even my fingerprint switcher key license expired.
The API Key is what is used in each fingerprint request, if it expires you won't be able to make new authorization requests until you purchase a new one. It's pretty cheap compared to what you can accomplish and gain with the use of it for your scripts.
