Node Reference
Workflows are built from nodes — each node is one step that does a single job (start the workflow, make a decision, transform data, call a model, send a message, write to the CRM, and so on). Nodes are wired together on the canvas; data flows from one node to the next via variables.
This section is the catalog of every node type, grouped by category. Pick a category to see each node, its configuration, inputs, and outputs.
Node categories
| Category | What it's for |
|---|---|
| Triggers | Start a workflow — message received, CRM change, webhook, schedule, button click, etc. |
| Logic | Control flow — conditions, branches, loops, delays, and routing. |
| Data | Transform, map, filter, and reshape data moving through the workflow. |
| AI | LLM calls, prompts, agents, knowledge-base search and RAG. |
| Channel | Send email, SMS, WhatsApp, and other outbound messages. |
| CRM | Create, update, and query contacts, companies, deals, and tasks. |
| Integration | Call external services and connected third-party tools. |
| Output | Set workflow outputs and return results. |
| Voice | Voice-call steps for AI phone conversations. |
How nodes fit together
- Every workflow starts with a Trigger.
- Logic and Data nodes shape what happens next.
- AI, Channel, CRM, and Integration nodes do the work.
- Output nodes return results to whatever called the workflow.
