# Percent Routing

> Split call traffic across multiple paths by percentage

The **Percent Routing** node distributes incoming calls across multiple paths based on configured percentages. Output handles are **dynamic** — one per route.

## Behavior

* Assigns each call to a route based on the configured percentage distribution
* Percentages **must sum to 100** (validated at save time)
* Routes are processed probabilistically — over time, traffic distribution matches the configured percentages

## Configuration

| Parameter | Type  | Default           | Description                           |
| --------- | ----- | ----------------- | ------------------------------------- |
| `routes`  | array | 2 routes at 50/50 | List of route definitions (see below) |

### Route definition

Each entry in `routes`:

| Field        | Type   | Description                                                        |
| ------------ | ------ | ------------------------------------------------------------------ |
| `label`      | string | Display label for the route                                        |
| `percentage` | number | Percentage of traffic (0–100). All routes must sum to exactly 100. |

## Output handles

Output handles are dynamic — each route generates its own handle:

| Handle             | Description                     |
| ------------------ | ------------------------------- |
| **\[Route Label]** | Call was assigned to this route |

**Default routes:**

| Handle      | Percentage |
| ----------- | ---------- |
| **Route A** | 50%        |
| **Route B** | 50%        |
