# How to register your own HighQ OAuth app

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

This guide shows you how to register your own app with HighQ (Collaborate) to obtain your OAuth credentials (Client ID & Secret key). These are required to let your users grant your app access to their HighQ account.

<Note>
  HighQ Collaborate is self-hosted per customer, so app registration is done by a **system administrator** inside your own Collaborate instance, not a shared developer portal. OAuth credentials are also scoped to that one instance — if your organization runs more than one Collaborate instance, you'll need to register a separate app (and set up a separate Nango integration) for each.
</Note>

<Steps>
  <Step id="open-api-application-registration" title="Open API application registration">
    Log in to your Collaborate instance as a system administrator, open **System administration**, then select **API application registration**.

    The API is enabled by default but can be disabled per instance. If you don't see **API application registration** in system administration, email [support@highq.com](mailto:support@highq.com) to have it enabled for your instance.
  </Step>

  <Step id="add-application" title="Add a new application">
    Click **Add application**.
  </Step>

  <Step id="fill-application-details" title="Fill in the application details">
    * **Name** — identifies this integration for your admins (required)
    * **Redirect URL** — the callback URL the OAuth code is sent to. Use `https://api.nango.dev/oauth/callback` for Nango Cloud
    * Leave **Token expiration time**, **Status**, and **Show allow/deny screen** at their defaults unless you have a specific reason to change them
  </Step>

  <Step id="get-credentials" title="Save and get your credentials">
    Save the application. HighQ generates and displays the **Client ID** and **Secret key** for this app — copy both. If you ever need a new secret, use **Generate key** on this same page.
  </Step>
</Steps>

Once you have your Client ID and Secret key, see the [how do I link my account?](/docs/api-integrations/highq/connect) guide to find your hostname, then follow the [quickstart](/docs/api-integrations/highq#quickstart) to connect in Nango.
