Each Dash account has one client ID and secret, issued when an admin turns on the REST API. Your users can connect any Dash account with these credentials: the subdomain they enter decides which account their tokens are for. **1. Create a Dash account** If you don't have a Dash account, [start a free trial](https://www.dash.app/). **2. Turn on the REST API** Sign in to Dash as an account admin, go to **Admin** → **Integrations**, open the **REST API** tab and switch **Enable API** on. Copy the **Client ID** and **Secret key** that appear. **3. Add Nango's callback URL** On the same page, add `https://api.nango.dev/oauth/callback` to the allowed callback URLs (or your own [custom callback URL](https://nango.dev/docs/guides/auth/auth-guide.md#custom-oauth-callback-url-optional)). **4. Add the credentials in Nango** In your Dash integration in Nango, paste the client ID and secret. You don't need to add scopes: when a user connects, Nango asks for their Dash subdomain (`my-account` for `https://my-account.dash.app`) and requests the `subdomain:` scope Dash needs to know which account the token is for, plus `offline_access` for a refresh token. **5. Next** Follow the [*Quickstart*](https://nango.dev/docs/getting-started/quickstart.md). > [!NOTE] > > Switching **Enable API** off revokes the client ID and secret along with the saved callback URLs, and switching it on again issues a new client ID and secret, which you then update in Nango.
