Is there a way to check if a purchase is InAppPurchase or SubscriptionPurchase

[da9ish]

Currently, there's no way to check if a purchase is a subscription or in-app

export interface ProductPurchase {
  productId: string;
  transactionId?: string;
  transactionDate: number;
  transactionReceipt: string;
  purchaseToken?: string;
  //iOS
  quantityIOS?: number;
  originalTransactionDateIOS?: string;
  originalTransactionIdentifierIOS?: string;
  //Android
  dataAndroid?: string;
  signatureAndroid?: string;
  autoRenewingAndroid?: boolean;
  purchaseStateAndroid?: PurchaseStateAndroid;
  isAcknowledgedAndroid?: boolean;
  packageNameAndroid?: string;
  developerPayloadAndroid?: string;
  obfuscatedAccountIdAndroid?: string;
  obfuscatedProfileIdAndroid?: string;
  //Amazon
  userIdAmazon?: string;
  userMarketplaceAmazon?: string;
  userJsonAmazon?: string;
  isCanceledAmazon?: boolean;
}

export type InAppPurchase = ProductPurchase;

export interface SubscriptionPurchase extends ProductPurchase {
  autoRenewingAndroid?: boolean;
  originalTransactionDateIOS?: string;
  originalTransactionIdentifierIOS?: string;
}

My problem is that I need to hit a different API endpoint based on the purchase type (InAppPurchase & SubscriptionPurchase)
The current purchase object that's returned in purchaseUpdatedListener doesn't have anything that I can use to identify the type

Can someone help?
