# SDK authentication

> Authenticate SDK-related API calls

SKOR provides public and secret keys for SDK integrations. Contact support if you need keys for your integration.

## Public key

The public key can be used in client-side applications. It identifies your integration and is used when invoking the SDK in the browser.

Use the public key when initializing the SDK:

```js theme={null}
const sdk = Skor({
  publicKey: "YOUR_PUBLIC_KEY",
});
```

## Secret key

The secret key is used for server-side API calls. Keep it secure and do not expose it in client-side code.

To authenticate SDK-related API requests from your server, include the secret key in the request header:

```http theme={null}
x-api-secret: YOUR_SECRET_KEY
```

<Warning>
  Never expose your secret key in browser code, mobile apps, logs, or public repositories.
