# How to register your own Trustpilot OAuth app

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

This guide shows you how to register your own app with Trustpilot to obtain your OAuth credentials (API Key & API Secret). These are required to let your users grant your app access to their Trustpilot Business account data.

<Steps>
  <Step title="Create a Trustpilot Business account">
    You need a [Trustpilot Business](https://business.trustpilot.com) account with access to the API module to use the Trustpilot API. If your account doesn't have API access yet, [request access from Trustpilot](https://business.trustpilot.com/request-demo).
  </Step>

  <Step title="Create an application">
    1. Log in to your Trustpilot Business account.
    2. Go to **Integrations** -> **Developers** -> **APIs**.
    3. Under **Your Applications**, select **Create Application**.
    4. Give the application a name, and add the Nango callback domain to the redirect URI field:

    ```
    https://api.nango.dev/oauth/callback
    ```

    5. Confirm creation, then note the **API Key** (this is your Client ID) and **API Secret** (this is your Client Secret).
  </Step>

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

    <Note>If you're building a listed Trustpilot Partner Integration rather than a standard OAuth app, share your redirect URLs with your Trustpilot Partner Manager so they can be added to the OAuth 2.0 allowlist.</Note>
  </Step>
</Steps>

<Tip>
  Need to authenticate without a user login (e.g. for a backend job)? Use the [Trustpilot (Client Credentials)](/docs/api-integrations/trustpilot-cc) integration instead — it only requires the API Key and API Secret, no redirect URI setup.
</Tip>
