+<Info>
+  **Android subscription parameters:** `basePlanId` and `offerId` are optional parameters for identifying subscription plans and promotional offers in Google Play. These are only passed on Android and will be `undefined` on iOS.
+</Info>
+
+<Note>
+  The deprecated `makePurchase` handler is still supported for backward compatibility, but we recommend using the platform-specific handlers (`makePurchaseIOS` and `makePurchaseAndroid`) instead.
