# Generate Barcode

> Generate a unique barcode for a product variant

<Note>
  **V2 Preview** — This endpoint is part of the V2 API preview. Breaking changes may occur.
</Note>

## Overview

Generate a unique barcode using the shop's barcode configuration (type, prefix, and length). The barcode is validated for uniqueness against Shopify before being returned, so you can safely assign it to a variant without collisions.

This endpoint requires the barcode feature to be enabled by the merchant in shop settings.

### Use Cases

* Auto-generate barcodes when creating new product variants
* Replace missing barcodes on existing variants
* Generate barcodes in bulk for inventory labeling

### Required Scope

`products:write`

## Request Body

No request body is required. The barcode format (type, prefix, length) is determined by the shop's barcode configuration.
