Complete reference for declaring variables, writing expressions, and managing data flow in `.flow` files.

> **Read this before** adding variables or writing expressions in any flow. Incorrect variable declarations cause silent runtime failures that `flow validate` does not catch.

---

## Variables Overview

Every flow has a `variables` object at the top level of the `.flow` file. It contains three sections:

```json
{
  "variables": {
    "globals": [],
    "nodes": [],
    "variableUpdates": {}
  }
}
```

| Section | Purpose |
| --- | --- |
| `globals` | Workflow-level variables: inputs, outputs, and state |
| `nodes` | Node output variables (auto-generated when using CLI `node add`) |
| `variableUpdates` | Per-node expressions that update state variables |

The `.flow` file is a JSON document at `<ProjectName>.flow` in the project root. It is the **only file you should edit** — other generated files will be overwritten.

## Top-level structure

```json
{
  "id": "<uuid>",
  "version": "1.0.0",
  "name": "MyFlow",
  "nodes": [],
  "edges": [],
  "definitions": [],
  "bindings": [],
  "variables": {},
  "layout": {
    "nodes": {}
  }
}
```

`solutionId` and `projectId` may also appear at the top level — these are auto-populated by `uip maestro flow init` and packaging. Do not add them manually.

> **`bindings[]`** holds Orchestrator resource references for `uipath.core.*` resource nodes (rpa, agent, flow, agentic-process, api-workflow, hitl) and for connector-node connections. See [Bindings — Orchestrator resource bi…(5947 more chars)
