Once you have called `getProducts()`, and you have a valid response, you can call `buyProduct()`. Subscribable products can be purchased just like consumable products and users can cancel subscriptions by using the iOS System Settings.

```javascript
try {
// Will return a purchase object with a receipt which can be used to validate on your server.
const purchase = await RNIap.buyProduct('com.example.coins100');
this.setState({
receipt: purchase.transactionReceipt, // save the receipt if you need it, whether locally, or to your server.
});
} catch(err) {
// standardized err.code and err.message available
console.warn(err.code, err.message);
const subscription = RNIap.addAdditionalSuccessPurchaseListenerIOS(async (purchase) => {
this.setState({ receipt: purchase.transactionReceipt }, () => this.goToNext());
subscription.remove();
});
}
try {
// add additional iOS listener before purchasing
const subscription = RNIap.addAdditionalSuccessPurchaseListenerIOS(async (purchase) => {
this.handlePurchaseSuccess(purchase);
subscription.remove();
});

// Will return a purchase object with a receipt which can be used to validate on your server.
const purchase = await RNIap.buyProduct('com.example.coins100');
this.handlePurchaseSuccess(purchase);
} catch(err) {

Most likely, you'll want to handle the 'store kit flow' (detailed [here](https://forums.developer.apple.com/thread/6431#14831)), which happens when a user succesfully pays after solving a problem with his or her account - for example, when the credit card information has expired.
