Where to save additional details?

[techguydev]

I have been testing this package and it looks great.

I am using paypal recurring payments api, I know that payment is not part of this implementation but I would like to have a place where I could save the returned details of the subscription we get from paypal (orderID,Billingtoken,subscriptionID ) so I can use it later to check the subscription status with the payment provider.

Do we have to create the additional field or table ourselves or this package has a way to handle this additional data?

Thanks.
