# Set up Lightspeed Retail (X-Series) with Nango

> Register an OAuth app with Lightspeed Retail (X-Series) and connect it to Nango

This guide shows you how to register your own app with Lightspeed Retail (X-Series) to obtain your OAuth credentials (client ID & secret). These are required to let your users grant your app access to their Lightspeed Retail (X-Series) stores.

<Steps>
  <Step title="Register a developer account">
    If you haven't already, [register a Lightspeed developer account](https://developers.retail.lightspeed.app/register).

    <Note>Your developer account credentials are independent of your Lightspeed Retail (X-Series) store account — your existing store credentials will not work here.</Note>
  </Step>

  <Step title="Create a new application">
    Once signed in, you'll be redirected to your **Applications** list.

    1. Click **Create Application**.
    2. Fill in the required fields: app name, description, and the redirect URI.
    3. For the **Redirect URI**, enter the Nango callback URL: [https://api.nango.dev/oauth/callback](https://api.nango.dev/oauth/callback)
    4. Submit to create the app.

    You'll receive a **Client ID** and **Client Secret** — these identify your application and are required to complete the OAuth flow.

    <Note>A newly created app is marked as **Not Approved**. This is expected. Not Approved means your app can connect to up to **30 Lightspeed Retail (X-Series) stores**, which is sufficient for private apps and testing. You only need to request approval for public, production-ready applications.</Note>
  </Step>
</Steps>
