"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.",

Exemplo de fluxo de integração
A imagem a seguir mostra um exemplo de layout do editor de integração para este exemplo de código de integração.
Fazer upload e executar a integração de amostra
Para fazer upload e executar a integração de amostra, siga estas etapas:
- Salve a amostra de integração como um arquivo .json no sistema.
- No console do Google Cloud, acesse a página Application Integration.
- No menu de navegação, clique em Integrações. A página Integrações será exibida.
- Selecione uma integração existente ou clique em CRIAR INTEGRAÇÃO.
Caso você esteja criando uma nova integração, siga estas etapas:
- Digite um nome e uma descrição na caixa de diálogo Criar integração.
- Selecione uma região para a integração.
- Selecione uma conta de serviço para a integração. É possível mudar ou atualizar os detalhes da conta de serviço de uma integração a qualquer momento no painel info Resumo da integração na barra de ferramentas de integração.
- Clique em Criar.
Isso abre a integração na página do editor de integração.
- No editor de integração, clique em publishMenu "Fazer upload/download" e selecione Fazer upload da integração.
- Na caixa de diálogo do navegador de arquivos, selecione o arquivo salvo na etapa 1 e clique em Open.
Uma nova versão da integração é criada usando o arquivo enviado.
- No editor de integração, clique em Testar.
- Clique em Testar integração. Isso executa a integração e mostra o resultado da execução no painel Testar integração.
