Node Data Object Parameters

name — name of the node
isStart — whether the node is the start node. There can only be 1 start node in a pathway. Either true or false.
isGlobal — whether the node is a global node. Global nodes are nodes that can be used in multiple pathways. Either true or false.
globalLabel — the label of the global node. Should be present if isGlobal is true.
type — Type of the node. Can be Default, End Call, Transfer Node, Knowledge Base, or Webhook.
text — If static text is chosen, this is the text that will be said to the user.
prompt — If dynamic text is chosen, this is the prompt that will be shown to the user.
condition — The condition that needs to be met to proceed from this node.
transferNumber
- If the node is a transfer node, this is the number to which the call will be transferred.
kb
- If the node is a knowledge base node, this is the knowledge base that will be used.
pathwayExamples
- The fine-tuning examples for the agent at this node for the pathways chosen
conditionExamples
- The fine-tuning examples for the condition at this node for the condition chosen
dialogueExamples
- The fine-tuning examples for the dialogue at this node for the dialogue chosen.
modelOptions
- modelName — The name of the model to be used for this node.
- interruptionThreshold — The sensitivity to interruptions at this node
- interruptibility — How readily the AI stops speaking when the caller talks over it on this node: 0 block (the AI finishes speaking, same as block_interruptions: true), 1 difficult, 2 balanced (default), 3 easy. Applies only while this node is active; other nodes use the agent’s setting. Useful per node: e.g. difficult on a legal-disclaimer node.
- temperature — The temperature of the model.
extractVars
- An array of array of strings. [[varName, varType, varDescription]] e.g [["name", "string", "The name of the user"], ["age", "integer", "The age of the user"]]

Update the pathway’s global prompt by adding an object to the array of nodes.

Global Prompt

{
    "globalConfig": {
        "globalPrompt": "This is a phone call. Do not use exclamation marks.\n\nConvert 24HR format timings to 12 HR format - e.g 14:00 should be written as 2 PM."
    },
    "position": {
        "x": 0,
        "y": 0
    }
}

object[]

An array of edge objects that define the connections and flow between nodes in your pathway. Each edge contains:Common Edge Structure:

{
    "source": "source_node_id",
    "target": "target_node_id",
    "data": {
        "label": "When this path should be taken",
        // Optional: conditions, descriptions, etc.
    }
}

Edge Object Parameters

id — unique id of the edge
source — id of the source node
target — id of the target node
label — Label for this edge. This is what the agent will use to decide which path to take.

Real-world conversation flow patterns

Response

string

Can be success or error.

string

A unique identifier for the pathway (present only if status is success).

array of objects

Data about all the nodes in the pathway.

array of objects

Data about all the edges in the pathway.
