# OAuth Apps You can fetch the details of an OAuth app you have in your account by the `client_id`. See the full [Bitly documentation for OAuth apps](https://dev.bitly.com/v4/#operation/getOAuthApp) ## Fetch an OAuth app With the `client_id` of an OAuth app, you can fetch it directly. ```ruby client = Bitly::API::Client.new(token: token) oauth_app = client.oauth_app(client_id: client_id) ``` Or with the class method ```ruby oauth_app = Bitly::API::OAuthApp.fetch(client: client, client_id: client_id) ```
