Is it possible to add metadata to requestPurchase function ?

[CallbackDan]

Hi there!

When I use the requestPurchase method to initiate a purchase, I have data accessible that I need to deliver the product to the user. But when I receive the successful purchase object from the purchaseUpdatedListener (which might not be immediate), I don't have that data accessible anymore, so can't get the product to the user.

Is there a way to add metadata to the requestPurchase method so that it will be given to me in the successful purchase object from the purchaseUpdatedListener ?

Thanks in advance, Dan!
