Legacy endpoint - deprecated. Unversioned endpoints are scheduled for removal on July 31, 2026. A public v1 replacement is not currently listed in the v1 reference. This endpoint remains available for existing integrations until then.

Adds a node to a workflow. Each node is one step in the sequence. After creating your nodes, connect them with edges to define how leads transition between steps.

Node types

`node_type`	What it does
`VOICE_CALL`	Places an outbound call to the lead using the specified agent.
`TIME`	Waits for a configured duration before moving to the next step.
`CONDITIONAL`	Branches the workflow based on a condition (e.g., call outcome).
`APPLICATION`	Triggers an external action (e.g., a webhook or CRM update).
`CONVERTED`	Terminal node that marks the lead as successfully converted.
`DROPPED`	Terminal node that marks the lead as dropped from the sequence.

VOICE_CALL config example

{
  "node_type": "VOICE_CALL",
  "label": "First Outreach Call",
  "position_x": 100,
  "position_y": 100,
  "config": {
    "agent_id": "agt_abc123",
    "from_phone_number": "+912234567890"
  }
}

TIME delay config example

{
  "node_type": "TIME",
  "label": "Wait 2 Days",
  "config": {
    "delay_hours": 48
  }
}

CONDITIONAL config example

{
  "node_type": "CONDITIONAL",
  "label": "Check Call Outcome",
  "config": {
    "condition_field": "call_status",
    "branches": ["COMPLETED", "FAILED", "NO_ANSWER"]
  }
}

After creating a conditional node, add one edge per branch (labeled COMPLETED, FAILED, etc.) leading to the appropriate next node.
