# How to register your own SHOPLINE OAuth app

> Register an OAuth app with SHOPLINE and connect it to Nango

This guide shows you how to register your own app with SHOPLINE to obtain your OAuth credentials (app key & app secret). These are required to let merchants grant your app access to their SHOPLINE store.

<Note>
  Create a **Public app**, not a Custom app — Custom apps are scoped to a single merchant, so they can't be installed by multiple merchants.
</Note>

<Steps>
  <Step title="Create a developer account">
    Go to the [SHOPLINE Partner Portal](https://developer.myshopline.com/) and sign up for a developer account.
  </Step>

  <Step title="Create a new app">
    1. In the Partner Portal, go to **Apps**, then click **+ Create App** and choose **Public app** (not **Custom app**).
    2. Enter a name, and set the callback URL to `https://api.nango.dev/oauth/callback`.
    3. The App URL isn't used by Nango, so you can enter anything there.
  </Step>

  <Step title="Get your credentials">
    Once the app is created, open it and copy its **App Key** and **App Secret** — you'll use these as the client ID and client secret when configuring the integration in Nango.
  </Step>

  <Step title="Next">
    Follow the [*Quickstart*](/docs/getting-started/quickstart) to connect your first account.
  </Step>
