Add offer code information to transaction and/or server API responses

[Renszit]

Hi!

Is there currently a way to see which offer or discount (e.g. App Store offer code, introductory offer, or promo) was applied to a purchase?
either in the transaction data or through the server API?

I couldn’t find anything related in the docs. If it’s not supported yet, it would be really helpful to expose offer-related fields such as the offerIdentifier or offerType from StoreKit / Play Billing. That would make it easier to analyze offer usage and handle related logic server-side.

Thanks!
