Esempio di codice
{
"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.",

Esempio di flusso di integrazione
L'immagine seguente mostra un layout di esempio dell'editor di integrazione per questo esempio di codice di integrazione.
Carica ed esegui l'integrazione di esempio
Per caricare ed eseguire l'integrazione di esempio:
- Salva l'esempio di integrazione come file .json sul sistema.
- Nella console Google Cloud, vai alla pagina Application Integration.
- Nel menu di navigazione, fai clic su Integrations (Integrazioni). Viene visualizzata la pagina Elenco delle integrazioni.
- Seleziona un'integrazione esistente o creane una nuova facendo clic su Crea integrazione.
Se stai creando una nuova integrazione:
- Inserisci un nome e una descrizione nella finestra di dialogo Crea integrazione.
- Seleziona una regione per l'integrazione.
- Seleziona un account di servizio per l'integrazione. Puoi modificare o aggiornare i dettagli dell'account di servizio di un'integrazione in qualsiasi momento dal riquadro info Riepilogo dell'integrazione nella barra degli strumenti dell'integrazione.
- Fai clic su Crea.
L'integrazione viene aperta nell'editor dell'integrazione.
- Nell'editor dell'integrazione, fai clic sul publishmenu Carica/scarica e quindi seleziona Carica integrazione.
- Nella finestra di dialogo del browser di file, seleziona il file che hai salvato nel passaggio 1, quindi fai clic su Apri.
Viene creata una nuova versione dell'integrazione utilizzando il file caricato.
- Nell'editor di integrazione, fai clic su Test.
- Fai clic su Testa integrazione. Eseguendo questa operazione viene eseguita l'integrazione e il risultato viene visualizzato nel riquadro Testa integrazione.
