Send Message Node

The Send Message node (type: send_message) sends a message to the user. It supports plain text, variable interpolation, quick-reply buttons, media attachments, and rich content elements like cards and carousels.

When to Use

• You want to send a scripted message (greeting, confirmation, instructions).
• You need to display the output of a previous node (e.g., {{llm_response}}).
• You want to present quick-reply buttons for the user to choose from.
• You need to send images, videos, or file attachments.

Configuration

Property	Description	Default
Message Text	The text to send. Supports {{variable}} interpolation.	Empty
Multiple Messages	Send up to 3 messages in sequence (each appears as a separate bubble).	Disabled
Typing Delay	Simulated typing delay in milliseconds before the message appears. Creates a more natural feel.	0
Await Selection	When quick replies are present, pause execution until the user selects an option.	false

Variable Interpolation

Reference any session variable using double curly braces:

Hello {{user_name}}, your order {{order_id}} has shipped!
Estimated delivery: {{delivery_date}}.

Nested properties use dot notation:

Your order status is {{order_details.status}}.

Quick Replies

Quick replies display as tappable buttons below the message. Each button has:

Property	Description
Title	The text shown on the button
Action	What happens when tapped: reply (sends the title as a user message), url (opens a link), or postback (sends a custom payload)
Payload	Custom data sent with the action (for reply and postback)
URL	The link to open (for url action)
Style	Optional styling: variant (outline, filled, text), color, icon, border radius

Quick replies support language variants for multilingual bots. Each button can define alternate text for different languages.

Media Attachments

Attach images, videos, or files to the message:

Property	Description
Type	image, video, or file
URL	The URL of the media asset
Alt Text	Accessibility description (for images)

Message Variants

Enable Variant Mode to define multiple versions of the message with conditions. The first variant whose condition matches is sent. This is useful for personalizing messages based on user attributes:

Variant 1 (condition: user_tier == "premium"):
  "Welcome back, {{user_name}}! As a Premium member, here are your exclusive options."

Variant 2 (default):
  "Welcome, {{user_name}}! How can we help you today?"

Multilingual Support

The Message node supports language variants. If the conversation language (sys_language) matches a configured variant, that version is sent instead of the default message. Configure variants in the Config Panel under the language tab.

TIP

For simple "send and continue" flows, the Message node is all you need. For AI-generated responses, pair it with an LLM Response node and reference {{llm_response}} in the message text.

Handles

Handle	Direction	Description
Input	In	Receives execution from the previous node
Output	Out	Continues to the next node after the message is sent

WARNING

If Await Selection is enabled with quick replies, the flow pauses until the user taps a button. Make sure at least one quick reply is configured, or the conversation will stall.
