We are planning to release an app with subscriptions. But we can't test the offer code feature with the app distributed by TestFlight. So, I'm unsure how to measure the offer code campaign's success. I watched this video but still don't know how to collect the data of the date that people redeem the Offer Code. https://developer.apple.com/videos/play/tech-talks/10868/
If someone has already released the app with subscriptions and an offer code campaign, please let me know if we can do that!
offerType and offerIdentifier are available in JWS signed transaction.
If offerType is 3, then it means the transaction is redeemed via offer code. You can check the purchaseDate of the transaction which represents the date of the offer code redemption unless it's restored.
Please refer to the document for the JWS signed transaction
I hope we could see these data, which are the offerIdentifier, offerType, and purchaseDate, on App Analitics of App Store Connect so that we don't need to implement something. Can we do that?
You can find the #of redemptions by each offer in Subscription report. Please refer to this document https://developer.apple.com/help/app-store-connect/reference/subscription-report.
