# Find publishable key

> Locate your account's publishable key to initialize Smile's JavaScript SDK.

Your publishable key is a unique identifier for your account and is safe to expose publicly. It is used to [initialize Smile's JavaScript SDK](https://dev.smile.io/js/initializing), allowing you to deeply integrate Smile rewards data and functionality into your website or application.

To initialize the SDK, you'll also need a [signing key](/en/articles/11878129-manage-signing-keys).
