Nesta página, explicamos como criar um complemento do Google Workspace que permite que os usuários do Documentos Google criem recursos, como um caso de suporte ou tarefa de projeto, em um serviço de terceiros no Documentos Google.
Com um complemento do Google Workspace, você pode adicionar seu serviço ao menu @ no Documentos. O complemento adiciona itens de menu que permitem aos usuários criar recursos no seu serviço em uma caixa de diálogo de formulário no app Documentos.
Como os usuários criam recursos
Para criar um recurso no serviço dentro de um documento do Documentos Google, 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 cartão que inclui as entradas de formulário que eles precisam para criar um recurso. Depois que o usuário envia o formulário de criação de recurso, o complemento precisa
criar o recurso no serviço e gerar um URL que aponte para ele.
O complemento insere um ícone no documento do recurso criado. Quando os usuários seguram o ponteiro sobre esse ícone, ele invoca o acionador de visualização do link associado do 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 com suporte a visualizações de links para os padrões de vinculação dos recursos criados pelos usuários. Para criar um complemento com visualizações de links, consulte Acessar links com ícones inteligentes.
Node.js
- Um complemento do Google Workspace com suporte a visualizações de links para os padrões de vinculação dos recursos criados pelos usuários. Para criar um complemento com visualizações de links, consulte Acessar links com ícones inteligentes.
Python
- Um complemento do Google Workspace com suporte a visualizações de links para os padrões de vinculação dos recursos criados pelos usuários. Para criar um complemento com visualizações de links, consulte Acessar links com ícones inteligentes.
Java
- Um complemento do Google Workspace com suporte a visualizações de links para os padrões de vinculação dos recursos criados pelos usuários. Para criar um complemento com visualizações de links, consulte Acessar links com ícones inteligentes.
Configurar a criação de recursos para o complemento
Nesta seção, explicamos como configurar a criação de recursos no seu complemento, incluindo as seguintes etapas:
- Configure a criação de recursos no recurso de implantação ou no arquivo de manifesto do complemento.
- Crie os cards de formulário de que os usuários precisam para criar recursos no seu serviço.
- Gerencie os envios de formulário 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 seguintes seções e campos no recurso de implantação ou no arquivo de manifesto do complemento:
Na seção
addOns, no campodocs, implemente o gatilhocreateActionTriggersque inclui umrunFunction. Defina essa função na seção a seguir, Criar os cards de formulário.Para saber mais sobre quais campos podem ser especificados no acionador
createActionTriggers, consulte a documentação de referência dos arquivos de manifesto do Apps Script ou dos recursos de implantação para outros ambientes de execução.No campo
oauthScopes, adicione o escopohttps://www.googleapis.com/auth/workspace.linkcreatepara que os usuários possam autorizar o complemento a criar recursos. Especificamente, esse escopo permite que o complemento leia as informações que os usuários enviam ao formulário de criação de recursos e insira um ícone inteligente no documento com base nessas informações.
Como exemplo, consulte a seção addons de um recurso de implantação 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 Documentos
- Um URL de logotipo que aponta para um ícone que aparece ao lado do texto do rótulo no menu "@"
- Função de callback que faz referência a uma função do Apps Script ou a um endpoint HTTP que retorna um cartão
Criar os cards de formulário
Para criar recursos no serviço pelo menu @ do Documentos, implemente todas as funções
especificadas no objeto createActionTriggers.
Quando um usuário interage com um dos seus itens de menu, o acionador
createActionTriggers correspondente é disparado, e a função de callback apresenta um cartão
com entradas de formulário para criar o recurso.
Elementos e ações compatíveis
Para criar a interface do cartão, use widgets para exibir 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:
- O rodapé do cartão não é compatível.
- Não há suporte para notificações.
- Somente a navegação
updateCardtem suporte.
Exemplo de cartão com entradas de formulário
O exemplo a seguir mostra uma função de callback do Apps Script que mostra um card quando um usuário seleciona Criar caso de suporte no menu @:

A função createCaseInputCard renderiza o card a seguir:
O card inclui entradas de texto, um menu suspenso e uma caixa de seleção. Ele também tem um
botão de texto com uma ação onClick, 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 do usuário ideal, seu complemento precisa processar
envios de formulário bem-sucedidos e incorretos.
Processar a criação de recursos bem-sucedida
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 aos Documentos
para a criação de ícones, 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 um SubmitFormResponse para um recurso criado:
Apps Script
apps-script/3p-resources/3p-resources.gs
/**
* Returns a submit form response that inserts a link into the document.
*
* @param {string} title The title of the link to insert.

action.add("links", links);
JsonObject renderActions = new JsonObject();
renderActions.add("action", action);
JsonObject linkRenderAction = new JsonObject();

return linkRenderAction;
}
Depois que SubmitFormResponse é retornado, a caixa de diálogo modal é fechada, e o
complemento insere um ícone no documento.
Quando o usuário mantém o ponteiro sobre esse ícone, ele invoca o acionador
de visualização de link associado. Verifique se o complemento não insere
ícones com padrões de link não compatíveis com os acionadores de visualização de links.
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 exibe um erro usando uma navegação updateCard.
Isso permite que o usuário veja o que fez
errado e tente novamente. Consulte
updateCard(card)
para o
Apps Script e updateCard
para outros ambientes de execução. Não há suporte para notificações e navegações do pushCard.
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 cartão vai ser atualizado e mostrar mensagens de erro. Se as entradas forem válidas,
o complemento retornará 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 nos Documentos Google.
O exemplo faz o seguinte:
- Gera um cartão com campos de formulário para criar um caso de suporte no menu @ do Documentos.
- 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 arquivo do Documentos como um ícone inteligente.
- Prévia do link para o caso de suporte, como
https://www.example.com/support/cases/1234. O ícone inteligente mostra um ícone, e o card de visualização inclui o nome, a prioridade e a descrição do caso.
