# Node Reference

> Explore the Node reference documentation for configuring Flows in Cognigy, including Basic, Logic, Voice, Analytics, Service, AI, and other Node categories.

This Node reference provides details about the [Nodes'](https://docs-classic.cognigy.com/ai/agents/develop/nodes/overview) parameters to help you configure your [Flow](https://docs-classic.cognigy.com/ai/agents/develop/projects-and-flows/overview).

## Node Categories

> [card] [Basic](https://docs-classic.cognigy.com/ai/agents/develop/node-reference/basic/overview)
>
> Use Basic Nodes for basic conversational Flows, for example, the [Say Node](https://docs-classic.cognigy.com/ai/agents/develop/node-reference/basic/say.md) and the [Question Node](https://docs-classic.cognigy.com/ai/agents/develop/node-reference/basic/question.md).

> [card] [Logic](https://docs-classic.cognigy.com/ai/agents/develop/node-reference/logic/overview)
>
> Use Logic Nodes to control the Flow execution, for example, the [If Node](https://docs-classic.cognigy.com/ai/agents/develop/node-reference/logic/if.md) and the [Lookup Node](https://docs-classic.cognigy.com/ai/agents/develop/node-reference/logic/lookup.md).

> [card] [Voice](https://docs-classic.cognigy.com/ai/agents/develop/node-reference/voice/overview)
>
> Voice Nodes are for developing voice AI Agents.

> [card] [Analytics](https://docs-classic.cognigy.com/ai/agents/develop/node-reference/analytics/overview)
>
> Nodes for tracking and analyzing conversation data and taking advantage of Cognigy AI's comprehensive marketing functionality.

> [card] [CXone](https://docs-classic.cognigy.com/ai/agents/develop/node-reference/cxone/overview)
>
> Nodes for integrating NiCE CXone into your Flows.

> [card] [Service](https://docs-classic.cognigy.com/ai/agents/develop/node-reference/service/overview)
>
> Use Service Nodes to trigger external services, like databases and email servers. Additional services can be added through [Extensions](https://docs-classic.cognigy.com/ai/for-developers/extensions.md).

> [card] [AI](https://docs-classic.cognigy.com/ai/agents/develop/node-reference/ai/overview)
>
> AI Nodes are a collection of Nodes for Cognigy [NLU](https://docs-classic.cognigy.com/ai/platform-features/nlu/overview) and [Agentic AI](https://docs-classic.cognigy.com/ai/agents/overview.md).

> [card] [Data](https://docs-classic.cognigy.com/ai/agents/develop/node-reference/data/overview)
>
> Data Nodes are designed to manage, manipulate, process, or store data.

> [card] [Agent Copilot](https://docs-classic.cognigy.com/ai/agents/develop/node-reference/agent-copilot/overview)
>
> Nodes for creating the Agent Copilot workspace.

> [card] [xApps](https://docs-classic.cognigy.com/ai/agents/develop/node-reference/xApp/overview)
>
> Nodes for creating xApps.

> [card] [Other](https://docs-classic.cognigy.com/ai/agents/develop/node-reference/other-nodes/overview)
>
> Additional specialized Nodes.

If you want to create a custom Node, go to the [Extensions](https://docs-classic.cognigy.com/ai/for-developers/extensions.md) section.

> [!NOTE]
>
> Nodes can belong to multiple categories for easier search and navigation. In the following sections, each Node is assigned to a single category to avoid duplicated descriptions.

## Common Sections to All Node Types

### Settings

All Node types include the **Settings** section, which contains the following parameters:

| Parameter | Description |
| - | - |
| Label | The name of the Node that is displayed in the Flow editor. This is useful to distinguish between Nodes of the same type. |
| Comment | A comment that is displayed in the Flow editor. This is useful to add additional information about the Node. |
| Analytics Step | An [analytic step](https://docs-classic.cognigy.com/ai/agents/analyze/analytics-steps.md) to track which paths users take in the Flow. |

### Mocking

Use this section to control [Mocking](https://docs-classic.cognigy.com/ai/agents/test/mocking.md) at the Node level.
