This release syncs with OpenIAP v1.3.14, introducing iOS 18+ win-back offers, JWS promotional offers, Android 8.0+ product status codes, and important type cleanup.

New Features​

Win-Back Offers (iOS 18+)​

Win-back offers allow you to re-engage churned subscribers with special discounts or free trials.

import {requestPurchase} from 'expo-iap';

// Apply a win-back offer during subscription purchase
await requestPurchase({
  request: {
    apple: {
      sku: 'premium_monthly',
      winBackOffer: {
        offerId: 'winback_50_off',  // iOS 18+
      },
    },
  },
  type: 'subs',
});

Win-back offers are automatically presented via StoreKit Message when eligible, or can be applied programmatically.

JWS Promotional Offers (iOS 15+)​

A new simplified format for promotional offers using compact JWS strings, back-deployed to iOS 15.

await requestPurchase({
  request: {
    apple: {
      sku: 'premium_yearly',
      promotionalOfferJWS: {
        offerId: 'promo_20_off',
        jws: 'eyJhbGciOiJFUzI1NiI...', // Server-signed JWS
      },
    },
  },
  type: 'subs',
});

Introductory Offer Eligibility Override (iOS 15+)​

Override system-determined introductory offer eligibility.

await requestPurchase({
  request: {
    apple: {
      sku: 'premium_monthly',
      introductoryOfferEligibility: true, // Force eligible
    },
  },
  type: 'subs',
});

Product Status Codes (Android 8.0+)​

Get detailed feedback on why products couldn't be fetched.

import {fetchProducts} from 'expo-iap';
import type {ProductAndroid} from 'expo-iap';

const result = await fetchProducts({
  skus: ['product_1', 'product_2'],
  type: 'in-app',
});

result.forEach((product) => {
  const androidProduct = product as ProductAndroid;
  if (androidProduct.productStatusAndroid) {
    switch (androidProduct.productStatusAndroid) {
      case 'ok':
        // Product available
        break;
      case 'not-found':
        // SKU doesn't exist in Play Console
        break;
      case 'no-offers-available':
        // User not eligible for any offers
        break;
    }
  }
});

Suspended Subscriptions Support (Android 8.1+)​

Include suspended subscriptions when fetching available purchases. This feature required native code updates to pass the option through to the OpenIAP SDK.

import {getAvailablePurchases} from 'expo-iap';

const purchases = await getAvailablePurchases({
  includeSuspendedAndroid: true, // Include suspended subs
});

// Check if subscription is suspended
purchases.forEach((purchase) => {
  if (purchase.isSuspendedAndroid) {
    // Direct user to resolve payment issues
    // Do NOT grant entitlements for suspended subscriptions
  }
});

Important: Suspended subscriptions should NOT be granted entitlements. Users should be directed to the Play Store subscription center to resolve payment issues.

Sub-Response Codes (Android 8.0+)​

More granular error information for purchase failures.

// SubResponseCodeAndroid provides additional context:
// - 'no-applicable-sub-response-code'
// - 'payment-declined-due-to-insufficient-funds'
// - 'user-ineligible'

Type Cleanup​

Subscription-Only Fields Removed from RequestPurchaseIosProps​

The following fields have been removed from RequestPurchaseIosProps because they only apply to subscription purchases:

• winBackOffer - Win-back offers are subscription-only (iOS 18+)
• promotionalOfferJWS - JWS promotional offers are subscription-only
• introductoryOfferEligibility - Introductory eligibility is subscription-only

These fields remain available in RequestSubscriptionIosProps where they belong.

Migration: If you were incorrectly using these fields with one-time purchases, move them to subscription purchases with type: 'subs'.
