I'm sorry but I quite don't understand
I'm sorry but I quite don't understand when to use "checkout" and when "attach". My basic service is free, so I assume I do use "attach", when a new customer registers. When the customer later exceeds the included 10k AI Tokens, she can buy an AI-Addon that will give her 100k, do I then use "checkout" with only the addon product? Am I correct with my assumptions?
