When customers first buy in my external Checkout (I use Thrivecart) there is no was to make a zap directly to create an account in my app, so I could not get there content free immediatly. I have to manage eveything after they create it by there own. So I have to be super on point with recognize when they buy, then check if they still have an account, then check if the content is available and then maybe put it free manually....

It takes so long. I don't have many customers yet, but it is not the "Think big" way to manage customers I expected.
