I have setup offer codes and subscriptions for users to purchase, when a user signs up using an offer code outside of the app the offer code does not save into my database where the subscriptions are saved
the transaction is successful and validated by store kit but I cant see that that user used an offer code - an example
https://apps.apple.com/redeem/?ctx=offercodes&id=6744338284&code=ASKDOM
I then setup an edge function in supabase to retrieve the data that store kit sends back and im not sure where to find the offer code as it still doesnt save
is there an internal apple reference that they use as apposed to the users offer code i.e offer code askdomSA = P3050 for example
how can Identify if an offer code was used
thank you
