Recipes

Real-world KarFlows API patterns for ecommerce, bookings, OTP, and support.

Recipes show how to combine APIs and flows for common products.

Ecommerce order confirmation

Use Unified Messaging with fallback.

{
  "to": "{{customer.phone}}",
  "text": "Hi {{customer.name}}, your order #{{order.id}} has been received.",
  "channels": ["whatsapp_qr", "whatsapp_meta", "sms"],
  "deliveryMode": "fallback",
  "whatsappFrom": "447405993704",
  "sender": "SHOP"
}

Booking request

Use Automation Flow first, then Unified API when the booking is confirmed.

Login OTP

Use Unified OTP with fallback.

{
  "to": "[phone]",
  "channels": ["whatsapp_qr", "sms"],
  "deliveryMode": "fallback",
  "length": 6,
  "expiresIn": 300,
  "template": "Your login code is {{code}}. It expires in {{minutes}} minutes."
}

Urgent OTP to both WhatsApp and SMS

Use deliveryMode: "all".

{
  "to": "[phone]",
  "channels": ["whatsapp_qr", "sms"],
  "deliveryMode": "all"
}

Human support fallback

When an automated flow cannot solve a request:

1. Send a short handoff message.
2. Disable automation for the conversation.
3. Create an agent task.
4. Let the user continue with a human.
