Flow Builder
Flow structure
Required nodes, subflows and connection rules for the Flow Builder.
The main flow always follows a required backbone. Subflows have a simpler entry structure.
Main flow
Main Flow → Before conversation → Greeting message → next step
These nodes are structural and cannot be deleted.
Subflows
A subflow starts with:
Subflow → Entry conditions
It can be triggered by another flow through the Trigger subflow node. Use subflows to reuse common logic: for example, identity validation or address collection.
Node connection rules
| Source | Can connect to |
|---|---|
main | trigger |
trigger | greeting_message, conversation, message, custom_action, during_call_sms, transfer, booking, placeholder |
greeting_message | conversation, message, jump, trigger_subflow, custom_action, during_call_sms, transfer, booking, end, placeholder (cannot connect to branch without a conversation before) |
conversation | branch, message, jump, trigger_subflow, custom_action, during_call_sms, transfer, booking, end, placeholder |
message | greeting_message, conversation, message, branch, jump, trigger_subflow, custom_action, during_call_sms, transfer, booking, end, placeholder |
branch | conversation, message, jump, trigger_subflow, custom_action, during_call_sms, transfer, booking, end, placeholder |
jump | conversation, message, branch, trigger_subflow, custom_action, during_call_sms, transfer, booking, end, placeholder |
trigger_subflow | conversation, message, branch, jump, custom_action, during_call_sms, transfer, booking, end, placeholder |
custom_action, during_call_sms, transfer, booking | greeting_message, conversation, message, branch, jump, trigger_subflow, custom_action, during_call_sms, transfer, booking, end, placeholder |
end | after_conversation |
after_conversation | (no outputs) |
Placeholders
The Next step node is a visual placeholder. Replace it with real nodes as you expand the flow.
