How to get base plan id from purchaseUpdatedListener?

[sgwanlee]

Hello. Is there a possible way to get base plan Id from purchaseUpdatedListener?

I need to pass the base plan id to server when verifying the purchase receipt like the following.

 purchaseUpdateSubscription = purchaseUpdatedListener(
      async (purchase: SubscriptionPurchase | ProductPurchase) => {
        const payload =
          Platform.OS === 'ios'
            ? { receiptData: purchase.transactionReceipt }
            : {
                purchaseToken: purchase.purchaseToken,
                productId: purchase.productId,
                basePlanId: purchase.basePlanId,
              };
       await verifyMutate(payload);
       ...
