Set Variable

The Set Variable node creates a custom variable that you can use in later nodes. It's a simple way to store intermediate values or combine data from multiple sources.

Configuration​

  • Variable name — the name you'll use to reference this value later
  • Value — the value to store (supports {{variables}})

Accessing the Variable​

Once set, you can use the variable in any downstream node with:

{{variables.yourVariableName}}

For example, if you create a variable called greeting, you access it as {{variables.greeting}}.

Use Cases​

Store an Intermediate Value​

You want to build a personalized greeting that combines several pieces of data:

  • Variable name: greeting
  • Value: Hi {{name}}, thanks for being a {{membership_tier}} member since {{join_date}}!

Then use {{variables.greeting}} in a Send Message node later.

Combine Data from Multiple Sources​

After running several AI nodes, combine their outputs:

  • Variable name: summary
  • Value: Category: {{classification}}\nSentiment: {{extracted}}\nSuggested reply: {{ai_reply}}

Prepare Formatted Text​

Build a formatted message once and reuse it in multiple places:

  • Variable name: appointment_details
  • Value: Date: {{appointment_date}}\nTime: {{appointment_time}}\nDoctor: {{doctor_name}}\nLocation: {{clinic_address}}

Tips​

  • Variable names should be descriptive. Use follow_up_message instead of msg or x.
  • You can set multiple variables by chaining several Set Variable nodes.
  • Variables persist for the duration of the flow execution. They're available to every node that comes after the Set Variable node.
