getReceiptIOS return empty string

[Mazenelali]

Hello @hyochan

I’m currently using expo-iap for subscriptions in my app. However, when I call getReceiptIos(), it returns an empty string instead of the expected Base64-encoded receipt.

I’ve noticed that fields when i make purchase like transactionReceipt and purchaseToken are returned, but they appear to be JWT-encoded, which doesn’t align with my backend implementation — it’s designed to work with a Base64-encoded iOS receipt.

Could you please provide a quick guide on how to properly retrieve the iOS receipt ?

Thank you in advance for your support!

getReceiptIOS should no more exists you should validate your recepit with purchaseToken which jwsRepresentation on iOS.

/** Unified purchase token(jwsRepresentation for iOS, purchaseToken for Android) */
purchaseToken?: string;
