Node: Call Another Flow

End the current flow and automatically start another flow, maintaining the conversation context.

Overview

The Call Another Flow node allows you to modularize your chatbot flows, dividing large flows into smaller, reusable parts. When this node is reached, the current flow session ends and another flow starts automatically — without the customer noticing the transition.

Use cases:

• Reuse a greeting, triage, or closing flow in multiple contexts
• Divide a complex flow into independent modules
• Pass data collected from one flow to another

How to Add to a Flow

1. In the flow builder, drag the Call Another Flow node to the canvas (category Actions)
2. Click the node to open the configuration modal
3. Configure in 3 steps

Configuration

Step 1 — Flow

Select the flow you want to trigger. Use the search field to filter by name.

Step 2 — Start Node

Choose which node the destination flow should start from. If not selected, the flow will start from the default node (start).

💡 Flexibility

You can start the destination flow at any node, not necessarily the beginning. This allows creating different entry points for the same flow based on context.

Step 3 — Variables (optional)

Map variables you want to pass to the destination flow:

Column	Description
Left	Variable in the destination flow that will receive the value
Right	Value to be sent: fixed text or variable from the current flow

Mapping examples:

customer_name  ←  {{customer_name}}      (passes current flow variable)
origin         ←  whatsapp               (fixed value)
description    ←  Order #{{order_id}}    (interpolates multiple variables)

Behavior

When this node is reached during a conversation:

1. The current flow session is automatically ended
2. The destination flow is started with the mapped variables already available
3. The conversation continues seamlessly for the customer

⚠️ Note

This node has no output — it is always a terminal node. After it, the destination flow takes over completely.

Practical Example

Main Flow (General Service)
├── Greeting → Triage
├── Customer wants technical support?
│   └── "Call Another Flow" node
│       └── Flow: "Technical Support"
│           └── Start node: "Collect problem data"
│           └── Variables: reason = "{{contact_reason}}"
└── Customer wants sales?
    └── "Call Another Flow" node
        └── Flow: "Sales Qualification"

Best Practices

• ✅ Create modular flows for greeting, triage, and closing
• ✅ Use variable mapping to maintain context between flows
• ✅ Choose the correct entry node to avoid repeating steps
• ❌ Avoid creating loops (flow A calls B, which calls A again)
