Android subscription offers not working correctly - always shows first base plan regardless of offerToken

[cddceo]

Description

When using multiple base plans (monthly/yearly) under a single Android subscription product, the Google Play
purchase dialog always shows the first base plan (1month) regardless of which offerToken is passed.

Environment

• react-native-iap version: 14.3.7
• Platform: Android

Current Setup

Google Play Console configuration:

• SKU: premium
• Base Plan 1: 1month (with offerToken)
• Base Plan 2: 1year (with offerToken)

Code Implementation

// Fetching subscriptions
fetchProducts({ skus: ['premium'], type: 'subs' })

// Processing subscription offers
subscriptions[0].subscriptionOfferDetailsAndroid.forEach((e) => {
    if (e.basePlanId === '1month') {
        // Save 1month details with offerToken
    } else if (e.basePlanId === '1year') {
        // Save 1year details with offerToken
    }
})

// Purchase request
await requestPurchase({
    request: {
        android: {
            skus: ['premium'],
            subscriptionOffers: [{
                sku: 'premium',
                offerToken: selectedSub.offerToken // Different token for each plan
            }],
        },
    },
    type: 'subs',
})

Expected Behavior

- When selecting 1month plan → Google Play should show monthly subscription
- When selecting 1year plan → Google Play should show yearly subscription

Actual Behavior

- Always shows 1month subscription regardless of which offerToken is passed
- The offerToken values are confirmed to be different for each base plan

Investigation

Looking at the type definitions, AndroidSubscriptionOfferInput only has:
export interface AndroidSubscriptionOfferInput {
  offerToken: string;
  sku: string;
}

There's no basePlanId field to specify which base plan to purchase. It seems the library doesn't fully support
Google Play Billing Library 5.0's new subscription model where:
- Product → Base Plan → Offer

Question

Is there a way to specify which base plan to purchase when a single product has multiple base plans? Or is this a
limitation of the current implementation?

Possible Solutions

1. Add basePlanId field to AndroidSubscriptionOfferInput
2. Create separate products for each subscription period (like iOS)
3. Any other recommended approach?

Thank you for your help!

@cddceo Thank you for the issue! This issue has actually raised in similar library expo hyochan/expo-iap#207 which I thought I've also resolved it here 😔

The issue you described was due to a bug in the Android bridge up to 14.3.7, where subscriptionOffers were not passed down to the native layer.
As a result, Google Play would always pick the first base plan regardless of the offerToken provided.

I’ve just merged a fix #3017 into 14.3.9.

Key changes

• The Nitro → OpenIAP bridge (HybridRnIap) now forwards the subscriptionOffers array directly to the OpenIAP 1.1.12 API.
• Added a JS unit test to verify that the given offerToken is passed through unchanged.

This means if you put the stored offerToken for your “1month/1year” offers into requestPurchase, the correct base plan should now be selected.

👉 Please update to 14.3.8 and let me know if the issue persists.
