# Reset the SDK

> `Smile.reset()`

This method resets the SDK to an uninitialized state, clearing all stored data including the customer session, preloaded resources, and configuration settings (like publishable key). It's primarily intended for use during cleanup operations or during development.

<Tip>
  If you only need to log out a customer, use [`Smile.customer.logout()`](/js/resources/customer/logout) instead.
</Tip>

## Returns

Void. This method does not return a value.

## Good to know

* After calling `Smile.reset()`, you must call [`Smile.initialize()`](/js/smile/initialize) again before using any other SDK methods.

* Attempting to call SDK methods after `Smile.reset()` (and before reinitializing) will throw an error.

* This is different from [`Smile.customer.logout()`](/js/resources/customer/logout), which only logs out the customer but keeps the SDK initialized.

* If you only need to log out a customer, use [`Smile.customer.logout()`](/js/resources/customer/logout) instead.
