# Update Product

> Full product update via Shopify productSet mutation

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

## Overview

Full update via Shopify's `productSet` mutation. Accepts a Shopify numeric ID, Shopify GID, or MongoDB ObjectId for `productId`. Vendor tokens can only update their own products.

<Warning>
  `variants`, `options`, and `metafields` arrays **replace** existing values. Partial updates on these arrays are not supported — send the full desired state.
</Warning>

## Path Parameters

<ParamField path="productId" type="string" required>
  Product ID (Shopify numeric, GID, or MongoDB ObjectId).
</ParamField>

## Request Body

Full product replacement payload. See the `ProductUpdateRequest` schema in the OpenAPI spec for the full field list (title, descriptionHtml, productType, vendor, status, variants\[], options\[], media\[], metafields\[], etc.).
