En las guías de inicio rápido, se explica cómo configurar y ejecutar una app que llama a una API de Google Workspace. En esta guía de inicio rápido, se usa un enfoque de autenticación simplificado que es adecuado para un entorno de pruebas. Para un entorno de producción, te recomendamos que obtengas información sobre la autenticación y la autorización antes de elegir las credenciales de acceso adecuadas para tu app.
En esta guía de inicio rápido, se usan las bibliotecas cliente de la API recomendadas de Google Workspace para controlar algunos detalles del flujo de autenticación y autorización.

Requisitos previos
Para ejecutar esta guía de inicio rápido, necesitas cumplir con los siguientes requisitos previos:
Cómo configurar la pantalla de consentimiento de OAuth
Si usas un proyecto de Google Cloud nuevo para completar esta guía de inicio rápido, configura la pantalla de consentimiento de OAuth. Si ya completaste este paso para tu proyecto de Cloud, ve a la siguiente sección.
En la consola de Google Cloud, ve a Menú menu>Google Auth platform>Branding.
Si ya configuraste Google Auth platform, puedes configurar los siguientes parámetros de configuración de la pantalla de consentimiento de OAuth en Branding, Audience y Data Access. Si ves un mensaje que dice Google Auth platform aún no se configuró, haz clic en Comenzar:
En Información de la app, en Nombre de la app, ingresa un nombre para la app.
En Correo electrónico de asistencia del usuario, elige una dirección de correo electrónico de asistencia a la que los usuarios puedan comunicarse contigo si tienen preguntas sobre su consentimiento.
Haz clic en Siguiente.
En Público, selecciona Interno.
Haz clic en Siguiente.
En Información de contacto, ingresa una dirección de correo electrónico en la que puedas recibir notificaciones sobre cualquier cambio en tu proyecto.
Por el momento, puedes omitir la adición de permisos.
En el futuro, cuando crees una app para usarla fuera de tu organización de Google Workspace, deberás cambiar el Tipo de usuario a Externo. Luego, agrega los permisos de autorización que requiere tu app. Para obtener más información, consulta la guía completa Configura el consentimiento de OAuth.
Autoriza credenciales para una aplicación de escritorio
Para autenticar a los usuarios finales y acceder a los datos del usuario en tu app, debes crear uno o más IDs de cliente de OAuth 2.0. Un ID de cliente se usa con el fin de identificar una sola app para los servidores de OAuth de Google. Si tu app se ejecuta en varias plataformas, debes crear un ID de cliente independiente para cada una.
En la consola de Google Cloud, ve a Menú menu>Google Auth platform>Clientes.
Haz clic en Tipo de aplicación>App para computadoras.
En el campo Nombre, escribe un nombre para la credencial. Este nombre solo se muestra en la consola de Google Cloud.
Haz clic en Crear.
La credencial recién creada aparecerá en "IDs de cliente de OAuth 2.0".
Guarda el archivo JSON descargado como credentials.json y muévelo a tu directorio de trabajo.
Configura la app de Google Chat
Para llamar a la API de Google Chat, debes configurar una app de Google Chat. Para cualquier solicitud de escritura, Google Chat atribuye la app de Google Chat en la IU con la siguiente información.
En la consola de Google Cloud, ve a la página Configuración de la API de Chat:
En Información de la aplicación, ingresa la siguiente información:
En el campo Nombre de la app, ingresa Chat API quickstart app.
En el campo URL del avatar, ingresa https://developers.google.com/chat/images/quickstart-app-avatar.png.
En el campo Descripción, ingresa Quickstart for calling the Chat API.
En Funciones interactivas, haz clic en el botón de activación Habilitar funciones interactivas y colócalo en la posición desactivada para inhabilitar las funciones interactivas de la app de Chat.
Haz clic en Guardar.

Ejecuta la muestra
En tu directorio de trabajo, compila y ejecuta la muestra:
python3quickstart.py
La primera vez que ejecutes la muestra, se te solicitará que autorices el acceso:
Si aún no accediste a tu Cuenta de Google, hazlo cuando se te solicite. Si accediste a varias cuentas, selecciona una para usarla en la autorización.
Haz clic en Aceptar.
Tu aplicación de Python se ejecuta y llama a la API de Google Chat.
La información de autorización se almacena en el sistema de archivos, por lo que la próxima vez que ejecutes el código de muestra, no se te solicitará autorización.

The first run requires authorizing access through a Google account, with subsequent runs automatically using stored credentials.\n"],null,["Create a Python command-line application that makes requests to the\nGoogle Chat API.\n\nQuickstarts explain how to set up and run an app that calls a\nGoogle Workspace API. This quickstart uses a\nsimplified authentication approach that is appropriate for a testing\nenvironment. For a production environment, we recommend learning about\n[authentication and authorization](/workspace/guides/auth-overview)\nbefore\n[choosing the access credentials](/workspace/guides/create-credentials#choose_the_access_credential_that_is_right_for_you)\nthat are appropriate for your app.\n\nThis quickstart uses Google Workspace's recommended API client libraries\nto handle some details of the authentication and authorization flow.\n\nObjectives\n\n- Set up your environment.\n- Install the client library.\n- Set up the sample.\n- Run the sample.\n\nPrerequisites\n\nTo run this quickstart, you need the following prerequisites:\n\n- Python 3.10.7 or greater\n- The [pip](https://pypi.python.org/pypi/pip) package management tool\n- [A Google Cloud project](/workspace/guides/create-project).\n\n\n- A Business or Enterprise [Google Workspace](//support.google.com/a/answer/6043576) account with access to [Google Chat](//workspace.google.com/products/chat/).\n\n\u003cbr /\u003e\n\nSet up your environment\n\nTo complete this quickstart, set up your environment.\n\nEnable the API Before using Google APIs, you need to turn them on in a Google Cloud project. You can turn on one or more APIs in a single Google Cloud project.\n\n- In the Google Cloud console, enable the Google Chat API.\n\n [Enable the API](https://console.cloud.google.com/flows/enableapi?apiid=chat.googleapis.com)\n\nConfigure the OAuth consent screen\n\nIf you're using a new Google Cloud project to complete this quickstart, configure\nthe OAuth consent screen. If you've already\ncompleted this step for your Cloud project, skip to the next section.\n\n1. In the Google Cloud console, go to Menu menu \\\u003e **Google Auth platform** \\\u003e **Branding** .\n\n [Go to Branding](https://console.cloud.google.com/auth/branding)\n2. If you have already configured the Google Auth platform, you can configure the following OAuth Consent Screen settings in [Branding](https://console.cloud.google.com/auth/branding), [Audience](https://console.cloud.google.com/auth/audience), and [Data Access](https://console.cloud.google.com/auth/scopes). If you see a message that says **Google Auth platform not configured yet** , click **Get Started**:\n 1. Under **App Information** , in **App name**, enter a name for the app.\n 2. In **User support email**, choose a support email address where users can contact you if they have questions about their consent.\n 3. Click **Next**.\n 4. Under **Audience** , select **Internal**.\n 5. Click **Next**.\n 6. Under **Contact Information** , enter an **Email address** where you can be notified about any changes to your project.\n 7. Click **Next**.\n 8. Under **Finish** , review the [Google API Services User Data Policy](https://developers.google.com/terms/api-services-user-data-policy) and if you agree, select **I agree to the Google API Services: User Data Policy**.\n 9. Click **Continue**.\n 10. Click **Create**.\n3. For now, you can skip adding scopes. In the future, when you create an app for use outside of your Google Workspace organization, you must change the **User type** to **External** . Then add the authorization scopes that your app requires. To learn more, see the full [Configure OAuth consent](/workspace/guides/configure-oauth-consent) guide.\n\nAuthorize credentials for a desktop application To authenticate end users and access user data in your app, you need to create one or more OAuth 2.0 Client IDs. A client ID is used to identify a single app to Google's OAuth servers. If your app runs on multiple platforms, you must create a separate client ID for each platform.\n\n1. In the Google Cloud console, go to Menu menu \\\u003e **Google Auth platform** \\\u003e **Clients** .\n\n [Go to Clients](https://console.cloud.google.com/auth/clients)\n2. Click **Create Client**.\n3. Click **Application type** \\\u003e **Desktop app**.\n4. In the **Name** field, type a name for the credential. This name is only shown in the Google Cloud console.\n5. Click **Create** .\n\n\n The newly created credential appears under \"OAuth 2.0 Client IDs.\"\n6. Save the downloaded JSON file as `credentials.json`, and move the file to your working directory.\n\nConfigure the Google Chat app\n\nTo call the Google Chat API, you must configure a\nGoogle Chat app. For any write requests, Google Chat\nattributes the Google Chat app in the UI using\nthe following information.\n\n1. In the Google Cloud console, go to the Chat API **Configuration** page:\n\n [Go to Chat API Configuration page](https://console.cloud.google.com/apis/api/chat.googleapis.com/hangouts-chat)\n2. Under **Application info**, enter the following information:\n\n 1. In the **App name** field, enter `Chat API quickstart app`.\n 2. In the **Avatar URL** field, enter `https://developers.google.com/chat/images/quickstart-app-avatar.png`.\n 3. In the **Description** field, enter `Quickstart for calling the Chat API`.\n3. Under **Interactive features** , click the **Enable interactive features**\n toggle to the off position to disable interactive features for the\n Chat app.\n\n4. Click **Save**.\n\nInstall the Google client library\n\n- Install the Google client library for Python:\n\n pip install --upgrade google-apps-chat google-auth-httplib2 google-auth-oauthlib\n\nConfigure the sample\n\n1.
