  "description": "The integration mimics the back office e-commerce order processing. The request is expected to contain order with one or more line items as json object with sku, quantity, price, vendor etc. If the total price of the order goes beyond $100 then there will be an email sent to approve the order else the order will be processed successfully. For all the items which have vendor as external, there will be an external order created by making a rest call to the external server. The response of the integration will be total order value, filtered list of external items and list of http response status received for each rest call made per external line_item.",

Carregue e execute a integração de exemplo

Para carregar e executar a integração de exemplo, siga estes passos:

  1. Guarde o exemplo de integração como um ficheiro .json no seu sistema.
  2. Na Google Cloud Console, aceda à página Integração de aplicações.

    Aceda à solução Application Integration

  3. Clique em Integrações no menu de navegação do lado esquerdo para abrir a página Integrações.
  4. Selecione uma integração existente ou crie uma nova clicando em Criar integração.

    Se estiver a criar uma nova integração:

    1. Introduza um nome e uma descrição na caixa de diálogo Criar integração.
    2. Selecione uma região para a integração.
    3. Selecione uma conta de serviço para a integração. Pode alterar ou atualizar os detalhes da conta de serviço de uma integração em qualquer altura no painel Resumo da integração na barra de ferramentas de integração.
    4. Clique em Criar.

    Esta ação abre a integração no editor de integração.

  5. No editor de integração, clique em Menu de carregamento/transferência e, de seguida, selecione Carregar integração.
  6. Na caixa de diálogo do explorador de ficheiros, selecione o ficheiro que guardou no passo 1 e, de seguida, clique em Abrir.

    É criada uma nova versão da integração com o ficheiro carregado.

  7. No editor de integração, clique em Testar.
  8. Clique em Testar integração. Isto executa a integração e apresenta o resultado da execução no painel Testar integração.
