# How to register your own MYOB OAuth app

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

This guide shows you how to register your own app with MYOB to obtain your OAuth credentials (API key & secret). These are required to let your users grant your app access to their MYOB company file.

<Steps>
  <Step id="create-developer-account" title="Create a developer account">
    Go to [my.myob](https://my.myob.com/) and register for a developer account. Approval from MYOB is required before you can register an app.
  </Step>

  <Step id="create-app" title="Register your app">
    1. Once approved, sign in to [my.myob](https://my.myob.com/) and select your developer account from the account dropdown.
    2. Open the **Developer** tab and register a new app.
    3. Give your app a name and, for **Redirect URI**, add `https://api.nango.dev/oauth/callback`.
       <Note>The redirect URI must use `https://` — MYOB rejects `http://` redirect URIs.</Note>
  </Step>

  <Step id="get-credentials" title="Get your credentials">
    Copy the **API Key** and **Secret** shown for your app — you will need these when configuring the integration in Nango.
  </Step>

  <Step id="select-scopes" title="Select your scopes">
    Choose the granular data scopes your app needs. Legacy scopes such as `CompanyFile` are deprecated and no longer supported.
  </Step>

  <Step id="start-building-integration" title="Start building your integration">
    Follow the [Quickstart](/docs/getting-started/quickstart) guide to build your integration.
  </Step>
</Steps>

<Note>
  The MYOB user authorizing the connection must be an **Administrator** of the company file. During authorization, they select a single company file to connect — its GUID (`businessId`) is returned to Nango automatically and stored on the connection. To connect additional company files, repeat the authorization flow for each one.
