Using variables in chatbot responses

Variables let you store customer responses and use them later in the conversation.

What are variables?

Variables are named containers that hold data during a conversation:

• {customer_name} — Stored from an Ask Question node
• {order_id} — Stored from customer input
• {api_result} — Stored from an HTTP Request response

Setting variables

From Ask Question node

1. Add an Ask Question node
2. In settings, set "Save response as": customer_name
3. When customer answers, their response is stored

From Set Variable node

1. Add a Set Variable node
2. Set name: greeting value: Hello!
3. Useful for computed values or flags

From HTTP Request

1. Add an HTTP Request node
2. Map response fields to variables
3. e.g., order_status = response.data.status

Using variables in messages

Reference variables in any Send Message node:

Hi {customer_name}! Your order {order_id} status is: {order_status}

Built-in variables

Tips

1. Name clearly — order_id not var1
2. Set defaults — Handle cases where variable is empty
3. Use in conditions — Branch based on variable values
4. Don't overwrite — Use unique names for each piece of data
