​
Headers

​
authorization
string
required
Your API key for authentication.

​
Path Parameters

​
pathway_id
string
required
The unique identifier of the conversational pathway you want to update.

​
Body

​
name
string
The name of the conversational pathway
​
description
string
A description of the pathway
​
nodes
object[]
An array of node objects representing the conversation flow points in your pathway. Each node contains:Common Node Structure:
{
    "id": "unique_node_identifier",
    "type": "Node_Type",
    "data": {
        "name": "Display Name",
        // Node-specific configuration goes here
    }
}
Available Node Types: Default, End Call, Transfer Call, Webhook, Knowledge Base, SMS, Custom Code, Press Button, Wait for Response, Transfer Pathway, Scheduling, and more.Node Examples:
{
  "id": "1",
  "type": "Default"
  "data": {
      "name": "Start",
      "text": "Hey there, how are you doing today?",
      "isStart": true,
  },
}
  • 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
    • 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
    }
}
​
edges
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.
    }
}
  • 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.

  • Multiple node types (Default, Transfer Call, Webhook, End Call, etc.)
  • Complex edge routing and conditions
  • Variable extraction and model configuration
  • Real-world conversation flow patterns

​
Response

​
status
string
Can be success or error.
​
pathway_id
string
A unique identifier for the pathway (present only if status is success).
​
nodes
array of objects
Data about all the nodes in the pathway.
​
edges
array of objects
Data about all the edges in the pathway.
