Crie um aplicativo de linha de comando em Python que faça solicitações para a API Google Chat.
Os guias de início rápido explicam como configurar e executar um app que chama uma API do Google Workspace. Este guia de início rápido usa uma abordagem de autenticação simplificada adequada para um ambiente de teste. Para um ambiente de produção, recomendamos aprender sobre autenticação e autorização antes de escolher as credenciais de acesso adequadas para seu app.
Este guia de início rápido usa as bibliotecas de cliente de API recomendadas do Google Workspace para processar alguns detalhes do fluxo de autenticação e autorização.
Objetivos
Prepare o ambiente.
Instale a biblioteca de cliente.
Configure a amostra.
Execute a amostra.
Pré-requisitos
Para executar este guia de início rápido, você precisa dos seguintes pré-requisitos:
Para concluir este guia de início rápido, configure seu ambiente.
Ativar a API
Antes de usar as APIs do Google, é necessário ativá-las em um projeto do Google Cloud. É possível ativar uma ou mais APIs em um único projeto do Google Cloud.
No console do Google Cloud, ative a API Google Chat.
Se você estiver usando um novo projeto do Google Cloud para concluir este guia de início rápido, configure a tela de consentimento do OAuth. Se você já concluiu esta etapa para seu projeto do Cloud, pule para a próxima seção.
No console do Google Cloud, acesse Menu menu>>Branding.
Se você já tiver configurado o , poderá definir as seguintes configurações da tela de permissão do OAuth em Branding, Público-alvo e Acesso a dados. Se aparecer uma mensagem informando que ainda não foi configurado, clique em Começar:
Em Informações do app, no campo Nome do app, insira um nome para o app.
Em E-mail para suporte do usuário, escolha um endereço de e-mail para que os usuários entrem em contato com você se tiverem dúvidas sobre o consentimento deles.
Clique em Próxima.
Em Público-alvo, selecione Interno.
Clique em Próxima.
Em Informações de contato, insira um Endereço de e-mail para receber notificações sobre mudanças no seu projeto.
Por enquanto, você pode pular a adição de escopos. No futuro, quando você criar um app para uso fora da sua organização do Google Workspace, mude o Tipo de usuário para Externo. Em seguida, adicione os escopos de autorização necessários para o app. Para saber mais, consulte o guia completo Configurar a permissão OAuth.
Autorizar credenciais para um aplicativo de computador
Para autenticar usuários finais e acessar dados de usuários no app, crie um ou mais IDs do cliente OAuth 2.0. Um ID do cliente é usado para identificar um único app nos servidores OAuth do Google. Se o app for executado em várias plataformas, crie um ID do cliente separado para cada uma delas.
No console do Google Cloud, acesse Menu menu>>Clientes.
No campo Nome, digite um nome para a credencial. Esse nome é mostrado apenas no console do Google Cloud.
Clique em Criar.
A credencial recém-criada aparece em "IDs de cliente OAuth 2.0".
Salve o arquivo JSON baixado como credentials.json e mova-o para o diretório de trabalho.
Configurar o app Google Chat
Para chamar a API Google Chat, configure um app Google Chat. Para qualquer solicitação de gravação, o Google Chat atribui o app Google Chat na interface usando as seguintes informações.
No console do Google Cloud, acesse a página Configuração da API Chat:

Executar a amostra
No diretório de trabalho, crie e execute a amostra:
python3quickstart.py
Na primeira vez que você executar a amostra, será necessário autorizar o acesso:
Faça login na sua Conta do Google, caso ainda não tenha feito isso. Se você tiver feito login em várias contas, selecione uma para usar na autorização.
Clique em Aceitar.
O aplicativo Python é executado e chama a API Google Chat.
As informações de autorização são armazenadas no sistema de arquivos. Assim, na próxima vez que você executar o código de amostra, não será necessário fazer a autorização.

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.
