Node Reference

Complete reference for all automation node types, organized by category

Last updated 8 Oct 2026Reference · article 8 of 9

Automations are built by connecting nodes. Each node has a specific role — receiving data, transforming it, enriching it with AI or external APIs, controlling flow, and producing outputs.

All node execution is subject to governance controls — guardrails are evaluated, confidence is scored, and runs are logged to the audit trail.

Entry Nodes

Where data enters your automation.

NodeDescription
UploadImport CSV, XLSX, or GeoJSON files
AudienceUse a saved audience as input
Text InputSupply static text directly

Transform Nodes

Reshape, filter, and route your data.

NodeDescription
ConditionBranch records to Match or No Match outputs
SplitDistribute records by percentage, sequence, or hash
SwitchRoute records to multiple outputs via expressions
TransformRename fields, coerce types, compute expressions
ScoreAdd computed scoring columns
Lookup JoinJoin two inputs on a key field
Set VariableStore automation-level variables

Enrich Nodes

Add data from external sources or AI models.

NodeDescription
Geo-ProfilingEnrich lat/lng records with census variables
LLMGenerate text or structured data with a language model
HTTPCall any external REST API
MCPCall tools on connected MCP servers
KB IngestIngest records into a knowledge base
RAG QueryQuery a knowledge base with semantic search
Knowledge SearchFull-text search of knowledge records
Memory WriteWrite to project memory or knowledge records

Flow Control Nodes

Pause, wait, and gate your automation.

NodeDescription
Approval GatePause and wait for human approval
QA ChecklistPause pending QA checklist completion
DelayWait for a configured duration
PollPoll for changes at a set interval
Sub-automationExecute another automation as a step

AI Nodes

Multi-step autonomous AI execution.

NodeDescription
AgentRun a multi-step AI agent with tools and MCP connections

Spatial Nodes

Geographic operations on coordinate data.

NodeDescription
BufferCreate a geographic buffer around coordinates
ClipIntersect or clip geographic datasets

Output Nodes

Send results somewhere.

NodeDescription
ExportExport results to external services
NotifySend email or webhook notifications
IntegrationPush data to a connected integration provider

Utility Nodes

Structural and grouping operations.

NodeDescription
GroupCombine streams with AND/OR/SEQUENCE logic

Template Syntax

LLM, Agent, HTTP, and MCP nodes support {{fieldName}} interpolation in their configuration. See Template Syntax for the full reference.
