# How to register your own Bling OAuth app

> Create a Bling app and connect its credentials to Nango

This guide shows you how to create a Bling app to get your OAuth credentials (client ID & secret). Your users then authorize your app to access their Bling account through the API v3.

**1. Create a Bling account**

If you don't have a Bling account, [sign up](https://www.bling.com.br) for one.

**2. Create an app**

1. In Bling, open the **Central de Extensões** and click **Área do integrador**.
2. Click **Criar aplicativo** and fill in the app's basic data.
3. Set the **Link de redirecionamento** to `https://api.nango.dev/oauth/callback` (or your own [custom callback URL](https://nango.dev/docs/guides/auth/auth-guide.md#custom-oauth-callback-url-optional)). A Bling app has a single redirect URL.
4. Choose the scopes your integration needs, for example products to list products.
5. Save, then copy the **Client ID** and **Client Secret** from the **Informações do app** tab.

**3. Add the credentials in Nango**

In your Bling integration in Nango, paste the client ID and secret. Leave scopes empty: Bling applies the scopes chosen on the app.

**4. Next**

Follow the [*Quickstart*](https://nango.dev/docs/getting-started/quickstart.md).
