What it means

expiredWebPurchaseToken (code 41) means the redemption link for a web purchase has expired, reported as backend code 7853. A new link is sent to the email used to buy. The error carries an obfuscated email so you can say where it went. Show that hint, and ask the customer to open the new link.

Causes

Why the SDK returns expiredWebPurchaseToken

  • The backend answered 7853 (expired web redemption token). The iOS SDK maps it here and returns the expired result with the obfuscated email (WebPurchaseRedemptionHelper.swift).
  • The customer opened the link after its validity period ended.
  • A newer link replaced this one, so the old token is treated as expired, not invalid.
  • Android maps 7853 to PurchaseInvalidError and has no member for this code (errors.kt).

Fix

How to fix expiredWebPurchaseToken

  1. 01

    Show the email hint

    Read rc_obfuscated_email from the error's userInfo, or the expired result's email, and show "We sent a new link to j***@example.com".

  2. 02

    Ask for the new link

    Tell the customer to open the newest email and use that link.

  3. 03

    Lengthen the validity

    If links expire too soon for your buyers, raise redemption_link_hours in the web config.

  4. 04

    Offer a support path

    If the buyer lost access to the email, route them to support with their order details.

How to handle it in code

  • Do not retry the old link. It stays expired.
  • Show the obfuscated email, so the customer knows where to look.
  • Do not grant access from the error. Access appears after redemption with the new link.
