    When you share the URL, you can include a `state` query parameter in the installation URL to preserve the state of the application page and return people back to that state after they install, authenticate, or accept updates to your GitHub App. For example, you could use the `state` to correlate an installation to a user or account.
 
    To preserve a state, add it to the installation URL: `{% data variables.product.oauth_host_code %}/{% ifversion ghes or ghae %}github-apps{% else %}apps{% endif %}/<app name>/installations/new?state=AB12t`
