Aha! connects with OAuth 2.0. The end user enters their Aha! subdomain, then signs in.

## Install the Aha integration

Install Aha from [Available integrations](https://app.truto.one/integrations/available/4c3fd8ae-6d70-4dc0-b6e5-35aeeed6a909) in each environment you connect accounts from.

## Use your own Aha OAuth app (optional)

Truto ships an Aha OAuth app, so OAuth 2.0 works without any setup. To show your own app on the consent screen instead, create an OAuth application in Aha!, register the redirect URL below, and set the app's Client ID and Client Secret on the installed integration. See [Overriding OAuth credentials](/docs/guides/integrations/overriding-oauth-credentials).

The subdomain is in the browser URL while you're signed in to Aha!.

4. Select **Aha**.
5. Fill in the form and click **Connect**:

   | Field | Required | What to enter |
   |---|---|---|
   | **Subdomain** | No | The first part of your Aha! URL: for `https://acme.aha.io`, enter `acme`. The form doesn't enforce it, but the Aha! sign-in page is on this subdomain, so enter it. |
6. Sign in to Aha and allow access.
7. Close the tab when you see the connection successful message. The new account appears under **Integrated Accounts**. Click its Account ID to see its details and make API calls.
