# How to register your own Datadog OAuth app

> Register an OAuth client with Datadog and connect it to Nango

This guide shows you how to register your own OAuth client with Datadog to obtain your OAuth credentials (client ID & secret). These are required to let your users authorize your app to access their Datadog account.

<Steps>
  <Step id="create-developer-account" title="Create a developer account">
    Datadog OAuth clients are created from a Datadog Partner Sandbox Account. Sign up for the [Datadog Developer Platform](https://docs.datadoghq.com/developers/authorization/oauth2_in_datadog/) if you don't already have one.
  </Step>

  <Step id="create-oauth-client" title="Create your OAuth client">
    In your Partner Sandbox Account's Developer Platform, create a new OAuth client and configure:

    * **Redirect URI**: `https://api.nango.dev/oauth/callback`
    * **Onboarding URL**: required by Datadog's form; Nango doesn't use it, so any placeholder URL works.
    * **Scopes**: select the scopes your app needs, following the principle of least privilege. See [Authorization scopes for OAuth clients](https://docs.datadoghq.com/api/latest/scopes/) for the full list. If you also need to call the [API Key Creation endpoint](https://docs.datadoghq.com/api/latest/key-management/#create-an-api-key) to send data on behalf of users, include `API_KEYS_WRITE`.
  </Step>

  <Step id="get-credentials" title="Get your credentials">
    Copy your **Client ID** and **Client Secret** from the OAuth client you created. You'll need these when configuring the integration in Nango.
  </Step>

  <Step id="configure-scopes" title="Configure scopes in Nango">
    In Nango, go to [Integrations](https://app.nango.dev/dev/integrations) -> *Datadog (OAuth)* and enter the **exact same scopes** in the integration's **Scopes** field that you selected on your Datadog OAuth client. Nango only requests the scopes listed there, and Datadog rejects any scope your OAuth client wasn't granted — so the two lists need to match.
  </Step>

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