Criar recursos de terceiros com o menu "@"

Nesta página, explicamos como criar um complemento do Google Workspace que permite aos usuários do Google Docs criar recursos, como um caso de suporte ou uma tarefa de projeto, em um serviço de terceiros no Google Docs.

Com um complemento do Google Workspace, você pode adicionar seu serviço ao menu @ nos Documentos. O complemento adiciona itens de menu que permitem aos usuários criar recursos no seu serviço usando uma caixa de diálogo de formulário no Documentos.

Como os usuários criam recursos

Para criar um recurso no seu serviço em um documento do Google Docs, os usuários digitam @ em um documento e selecionam seu serviço no menu @:

Quando os usuários digitam @ em um documento e selecionam seu serviço, você apresenta um card com as entradas de formulário necessárias para criar um recurso. Depois que o usuário enviar o formulário de criação de recursos, o complemento vai criar o recurso no seu serviço e gerar um URL que aponta para ele.

O complemento insere um ícone no documento para o recurso criado. Quando os usuários mantêm o ponteiro sobre esse ícone, ele invoca o gatilho de visualização de link associado ao complemento. Verifique se o complemento insere ícones com padrões de link compatíveis com os gatilhos de visualização de link.

Pré-requisitos

Apps Script

• Um complemento do Google Workspace que oferece suporte a visualizações de link para os padrões de link dos recursos criados pelos usuários. Para criar um complemento com prévias de links, consulte Visualizar links com ícones inteligentes.

Node.js

• Um complemento do Google Workspace que oferece suporte a visualizações de link para os padrões de link dos recursos criados pelos usuários. Para criar um complemento com prévias de links, consulte Visualizar links com ícones inteligentes.

Observação: os exemplos de código do Node.js foram escritos para serem executados como uma função do Cloud

Python

• Um complemento do Google Workspace que oferece suporte a visualizações de link para os padrões de link dos recursos criados pelos usuários. Para criar um complemento com prévias de links, consulte Visualizar links com ícones inteligentes.

Observação: os exemplos de código Python neste guia foram escritos para serem executados como uma Função do Cloud usando Python 3.9.

Java

• Um complemento do Google Workspace que oferece suporte a visualizações de link para os padrões de link dos recursos criados pelos usuários. Para criar um complemento com prévias de links, consulte Visualizar links com ícones inteligentes.

Configurar a criação de recursos para seu complemento

Esta seção explica como configurar a criação de recursos para seu complemento, o que inclui as seguintes etapas:

1. Configure a criação de recursos no manifesto do complemento.
2. Crie os cards de formulário que os usuários precisam para criar recursos no seu serviço.
3. Processe os envios de formulários para que a função que cria o recurso seja executada quando os usuários enviarem o formulário.

Configurar a criação de recursos

Para configurar a criação de recursos, especifique as seções e os campos a seguir no manifesto do complemento:

1. Na seção addOns do campo docs, implemente o gatilho createActionTriggers que inclui um runFunction. Você vai definir essa função na próxima seção, Criar os cards de formulário.

   Para saber quais campos podem ser especificados no gatilho createActionTriggers, consulte a documentação de referência para manifestos do Apps Script ou recursos de implantação para outros runtimes.

2. No campo oauthScopes, adicione o escopo https://www.googleapis.com/auth/workspace.linkcreate para que os usuários possam autorizar o complemento a criar recursos. Especificamente, esse escopo permite que o complemento leia as informações enviadas pelos usuários ao formulário de criação de recursos e insira um ícone inteligente no documento com base nessas informações.

   Observação: se você adicionar esse escopo a um complemento publicado, os usuários atuais vão precisar autorizar novamente o complemento para permitir o escopo adicionado.

Por exemplo, consulte a seção addons de um manifesto que configura a criação de recursos para o seguinte serviço de caso de suporte:

{
  "oauthScopes": [
    "https://www.googleapis.com/auth/workspace.linkpreview",
    "https://www.googleapis.com/auth/workspace.linkcreate"
  ],
  "addOns": {
    "docs": {
      "linkPreviewTriggers": [
        ...
      ],
      "createActionTriggers": [
        {
          "id": "createCase",
          "labelText": "Create support case",
          "localizedLabelText": {
            "es": "Crear caso de soporte"
          },
          "runFunction": "createCaseInputCard",
          "logoUrl": "https://www.example.com/images/case.png"
        }
      ]
    }
  }
}

No exemplo, o complemento do Google Workspace permite que os usuários criem casos de suporte. Cada gatilho createActionTriggers precisa ter os seguintes campos:

• Um ID exclusivo
• Um rótulo de texto que aparece no menu @ do Google Docs
• Um URL de logotipo que aponta para um ícone que aparece ao lado do texto do rótulo no menu @
• Uma função de callback que faz referência a uma função do Apps Script ou a um endpoint HTTP que retorna um card.

Criar os cards do formulário

Para criar recursos no seu serviço usando o menu @ do Google Docs, implemente as funções especificadas no objeto createActionTriggers.

Quando um usuário interage com um dos itens do menu, o gatilho createActionTriggers correspondente é disparado, e a função de callback apresenta um card com entradas de formulário para criar o recurso.

Elementos e ações compatíveis

Para criar a interface de card, use widgets para mostrar informações e entradas que os usuários precisam para criar o recurso. A maioria dos widgets e ações de complementos do Google Workspace é compatível, com as seguintes exceções:

• Rodapés de card não são aceitos.
• As notificações não são compatíveis.
• Para navegações, apenas a navegação updateCard é compatível.

Exemplo de card com entradas de formulário

O exemplo a seguir mostra uma função de callback do Apps Script que exibe um card quando um usuário seleciona Criar caso de suporte no menu @:

A função createCaseInputCard renderiza o seguinte card:

O card inclui entradas de texto, um menu suspenso e uma caixa de seleção. Ele também tem um botão de texto com uma açãoonClick que executa outra função para processar o envio do formulário de criação.

Depois que o usuário preenche o formulário e clica em Criar, o complemento envia as entradas do formulário para a função de ação onClick, chamada submitCaseCreationForm no nosso exemplo. Nesse momento, o complemento pode validar as entradas e usá-las para criar o recurso no serviço de terceiros.

Processar envios de formulário

Depois que um usuário envia o formulário de criação, a função associada à ação onClick é executada. Para uma experiência ideal do usuário, seu complemento precisa processar envios de formulários bem-sucedidos e com erros.

Processar a criação de recursos

A função onClick do complemento precisa criar o recurso no serviço de terceiros e gerar um URL que aponte para ele.

Para comunicar o URL do recurso de volta ao Documentos para a criação de um ícone, a função onClick precisa retornar um SubmitFormResponse com uma matriz de um elemento em renderActions.action.links que aponta para um link. O título do link precisa representar o título do recurso criado, e o URL precisa apontar para esse recurso.

O exemplo a seguir mostra uma SubmitFormResponse para um recurso criado:

Depois que o SubmitFormResponse é retornado, a caixa de diálogo modal é fechada e o complemento insere um ícone no documento. Quando os usuários mantêm o ponteiro sobre esse ícone, ele invoca o gatilho de prévia do link associado. Verifique se o complemento não insere chips com padrões de link não compatíveis com os gatilhos de visualização de link.

Solucionar erros

Se um usuário tentar enviar um formulário com campos inválidos, em vez de retornar um SubmitFormResponse com um link, o complemento vai retornar uma ação de renderização que mostra um erro usando uma navegação updateCard. Assim, o usuário pode ver o que fez de errado e tentar de novo. Consulte updateCard(card) para o Apps Script e updateCard para outros tempos de execução. Notificações e navegações pushCard não são compatíveis.

Exemplo de tratamento de erros

O exemplo a seguir mostra o código invocado quando um usuário envia o formulário. Se as entradas forem inválidas, o card será atualizado e mostrará mensagens de erro. Se as entradas forem válidas, o complemento vai retornar um SubmitFormResponse com um link para o recurso criado.

Exemplo completo: complemento de caso de suporte

O exemplo a seguir mostra um complemento do Google Workspace que visualiza links para os casos de suporte de uma empresa e permite que os usuários criem casos de suporte no Google Docs.

O exemplo faz o seguinte:

• Gera um card com campos de formulário para criar um caso de suporte no menu @ dos Documentos Google.
• Valida as entradas de formulário e retorna mensagens de erro para entradas inválidas.
• Insere o nome e o link do caso de suporte criado no documento do Google Docs como um ícone inteligente.
• Mostra uma prévia do link para o caso de suporte, como https://www.example.com/support/cases/1234. O ícone aparece no ícone inteligente, e o card de prévia inclui o nome, a prioridade e a descrição do caso.
