Objective: Automate the process of capturing customer orders using conversational AI, enriching data, validating, and saving into backend systems.
Workflow Design:
Trigger: User Interaction Initiation
- Trigger Node: Webhook
- Accepts incoming requests from your chatbot or conversational front-end (e.g., WhatsApp, website chat widget, or voice service integrated with Dialogflow or Twilio).
- Example payload:
{
“customerId”: “12345”,
“intent”: “PlaceOrder”,
“items”: [“ProductA”, “ProductB”],
“quantity”: [2, 1]
}
Fetch Customer Profile (optional enrichment)
- HTTP Request Node: Retrieve customer details from CRM API:
GET https://crm.example.com/api/customers/12345
Validate Inventory
- HTTP Request Node:
Query inventory system API to check availability of requested products:
POST https://inventory.example.com/check
GPT-based Confirmation Draft (optional)
- OpenAI Node:
Generate a human-like confirmation message for customer approval:
Prompt:
“Generate a polite message confirming order for {{items}} with quantities {{quantities}}, total price {{totalPrice}}.”
Conditional Branch: Stock Availability
- IF Node:
Check stock status for all requested products.
Create Order in Order Management System (OMS)
- HTTP Request Node:
Send a POST request to create the order:
POST https://oms.example.com/orders
Example payload:
{
“customerId”: “12345”,
“orderItems”: [{“product”: “ProductA”, “qty”: 2}, {“product”: “ProductB”, “qty”: 1}],
“total”: “150.00”
}
Send Order Confirmation to Customer
- HTTP Request or Messaging Node:
- Email: Send Email Node
- WhatsApp: WhatsApp API Node
- SMS: Twilio Node
Handle Failures
- If inventory not available → Notify customer gracefully.
