# Headless Web SDK Authentication

> Learn how to authenticate with the Suki Headless Web SDK

You must be a **Suki partner** to use the Suki Headless Web SDK. If you have not registered yet, read our [Partner onboarding](/documentation/partner-onboarding) guide.

Once you are a partner, you can authenticate with Suki services using your own authentication system.

## Prerequisites

To configure the Headless Web SDK, you must provide the following credentials:

* **Partner ID**: The unique identifier assigned to you during onboarding.

* **Partner Token**: The access token you generate for the user from your system.

<Note>
  To understand how authentication works for partners, see [Partner authentication](/documentation/partner-authentication).
</Note>

## Authenticate with React (recommended)

In React, create a **`PlatformClient`**, wrap your app with **`PlatformClientProvider`**, then use the **`useAuth`** hook under that tree. The hook simplifies user registration and token updates.
