# restorePurchases

{% hint style="info" %}
**Apple SDK only**

This method is only available from the Nami SDK for Apple devices, or cross-platform SDKs being used on Apple devices.
{% endhint %}

Restore replays all prior purchase transactions to determine which purchases are active. This function trigger an app store password prompt if called, so only call this at the request of the user.

Generally this is not needed if your Nami account supports purchase validation, as the receipt is checked every time the app comes to the foreground and can determine active purchases that way.

Learn more in our guide on [Restoring Purchases](doc:restoring-purchases) .

Activate the system restore purchases feature. Optionally calls back to a global `NamiRestorePurchasesStateHandler` handler with restore state if one is provided by\
