I am trying to put together a license/serial number system in v4. I want the user to be able to purchase the same product multiple times and each one has a different api key in the subscription/product purchase data. Where should I put this data? (I can generate the API key in the plugin, just don't know where I should store it within aMember.)
Ummm .. if you are using softsale it will handle that, otherwise add the field to the payment record and update it there you will then need to have it display etc...
