Agentes pré-criados

Os agentes pré-criados são um conjunto de agentes fornecidos pelo Dialogflow para casos de uso comuns. Semelhante aos agentes pré-criados do Dialogflow ES, eles podem ser usados para estabelecer uma base para a criação de conversas. No Dialogflow CX, você encontrará casos de uso comuns de todos os setores, como telecomunicações, serviços financeiros, saúde, varejo e viagens.

Os agentes pré-criados incluem intents e entidades para os casos de uso, mas você precisa modificar os grupos de rota e fulfillment (quando aplicável).

Limitações

Considere as seguintes limitações:

  • Atualmente, os agentes pré-criados só estão disponíveis em inglês (en).

Importar um agente pré-criado

Se você quiser importar um agente pré-criado para seu projeto, siga estas etapas:

  1. Acesse o Console do Dialogflow CX.
  2. Clique no projeto em que você quer importar o agente pré-criado.
  3. Clique em Usar agentes predefinidos.
  4. Clique no agente de interesse e em Importar.
  5. Escolha o local e clique em Criar.
  6. Comece a testar e personalizar.

Personalizar o agente pré-criado importado

  1. Teste o agente usando o simulador para entender o que ele pode ajudar os usuários a realizar.
  2. Clique na guia Gerenciar no painel esquerdo e em Casos de teste para ver a cobertura e os scripts de exemplo. Para mais informações, consulte a documentação dos Casos de teste.
  3. Exclua todos os fluxos irrelevantes para seu caso de uso.
  4. Edite o diálogo do agente e as entidades personalizadas para atender às necessidades da sua empresa.
  5. Se houver código-fonte do webhook, consulte Como modificar o código do webhook.

Como modificar o código do webhook

Uma seleção dos agentes pré-criados utiliza webhooks. O código-fonte do webhook original usa o Node.js e está hospedado no projeto interno do Cloud Functions do Google.

Para usar e modificar esse código no seu próprio projeto do Cloud Functions, siga as instruções a seguir:

  1. Acesse o Console do Dialogflow CX.
  2. Clique no projeto em que você quer importar o agente pré-criado.
  3. Clique em Usar agentes predefinidos.
  4. Clique no agente de interesse e depois em Link de documentação, que o levará para a seção de agente pré-criada deste documento.

    Captura de tela do cartão de agente pré-montado de pagamentos

  5. Consulte a subseção Webhook para o agente pré-criado e copie o código-fonte.

  6. Acesse o Console do Google Cloud e selecione Cloud Functions no painel à esquerda.

    Captura de tela do Cloud Function no menu do Console do Google Cloud

  7. Clique no projeto para o qual você quer importar o código-fonte.

  8. Clique em Criar função. Para mais instruções, consulte a documentação Criar uma função do Cloud Function.

  9. Na seção Código-fonte, selecione Editor in-line e cole o código-fonte copiado.

  10. Clique em Origem e Editar para alterar a lógica com base nas suas regras de negócios. Quando terminar, clique em Implantar.

  11. Clique em Acionador e copie o URL do acionador.

  12. Substitua o URL do acionador no seu agente em Gerenciar > Webhooks e selecionando o webhook para colar o novo URL. Cole o URL do acionador no campo "URL do webhook". Clique em Salvar.

  13. Usando a documentação do Webhooks, teste o fulfillment.

Agente de serviços financeiros

Esse modelo ajuda os usuários finais com cartões, verifica o status de uma inscrição e investiga cobranças suspeitas.

Exemplos de declarações

  • Quero efetuar um pagamento no meu saldo.
  • Perdi meu cartão e preciso de um novo.
  • Quero denunciar atividades suspeitas na minha conta corrente.
  • Qual é o status da minha inscrição de empréstimo automático?
  • Quais são as diferentes taxas anuais nos seus cartões de crédito empresariais?

Webhook

O webhook do Cloud Functions executa as seguintes ações:

  • Valida a identidade de um usuário final
  • Fornece amostras de saldos, status de empréstimo e informações de recursos de cartões de crédito
  • Simula os pagamentos de amostra, incluindo a validação de valores e datas de pagamentos
  • Controla o horário de funcionamento

Agente de saúde

Este modelo ajuda os usuários finais a verificar declarações, benefícios e encontrar um médico.

Exemplos de declarações

  • O que é cosseguro?
  • Você pode me ajudar a encontrar um médico?
  • Não estou me sentindo bem.
  • Qual é minha franquia?

Agente de gerenciamento de pedidos e contas

Esse modelo ajuda os usuários finais a comprar ou devolver um produto, rastrear pedidos e gerenciar configurações da conta, como pontos de fidelidade, endereços e senhas.

Exemplos de declarações

  • Não recebi meu pedido. Onde ele está?
  • Quero comprar um novo smartphone.
  • Esqueci a minha senha.
  • Você pode me dizer quantos pontos eu tenho?
  • Mudei e preciso atualizar meu endereço.

Agente de acordo com o pagamento

Esse modelo ajuda os usuários finais a configurar uma disposição de pagamento de duas parcelas ou estender uma data de vencimento.

Exemplos de declarações

  • Minha conta foi suspensa.
  • Não vou receber pagamentos em dia da minha conta.
  • Preciso estender minha data de entrega.
  • Perdi meu emprego devido à COVID-19.

Webhook

Este webhook do Cloud Functions executa as seguintes ações:

  • Informa o valor de amostra devido e as datas máximas de extensão.
  • Calcula a segunda parcela do pagamento com base na diferença entre o saldo total e a primeira parcela paga.
  • Valida se a data de extensão solicitada não ultrapassa a data de extensão máxima.

Viagem: agente para reivindicar bagagens

Esse modelo ajuda os usuários finais a criar ou verificar o status de uma reivindicação relacionada a bagagens perdidas, atrasadas ou danificadas.

Exemplos de declarações

  • Poderia me ajudar a abrir uma reivindicação de uma bagagem que você perdeu?
  • Quero saber o status da minha reivindicação de bagagem danificada.
  • Quando minha bagagem vai chegar?

Webhook

Este webhook do Cloud Functions executa as seguintes ações:

  • Verifica os detalhes do usuário e do voo.
  • Gera um ID da reivindicação e retorna informações dela.
