> Learn how to check whether an application is registered with Auth0 as a first-party or third-party app using the Auth0 Management API.

# View Application Ownership

You can use Auth0's <Tooltip tip="Management API: A product to allow customers to perform administrative tasks." cta="View Glossary" href="/docs/glossary?term=Management+API">Management API</Tooltip> to check whether an application is registered with Auth0 as a first-party or third-party application.

Make a `GET` call to the [Get a Client endpoint](https://auth0.com/docs/api/management/v2#!/Clients/get_clients_by_id). Be sure to replace `{yourClientId}`
and `{yourMgmtApiAccessToken}` placeholder values with your <Tooltip tip="Client ID: Identification value given to your registered resource from Auth0." cta="View Glossary" href="/docs/glossary?term=client+ID">client ID</Tooltip> and Management API <Tooltip tip="Access Token: Authorization credential, in the form of an opaque string or JWT, used to access an API." cta="View Glossary" href="/docs/glossary?term=Access+Token">Access Token</Tooltip>, respectively.

If the application is first-party, the `is_first_party` field will have a value of `true`. If the application is third-party, the `is_first_party` field will have a value of `false`.
