# Nodes

A flow is made up of nodes. Each node serves a specific purpose: connecting to third-party services, transforming data, performing conditional logic and returning responses.

## Name

Each node is given a unique name, e.g. `node_1`, which can be used to reference its data and/or metadata.

To rename a node click the node's name.

{% hint style="warning" %}
Renaming a node does not update the existing references to the node. We recommend that you name a node before creating references to it.
{% endhint %}

## Output Data

### Outputs
