# product_variants_bulk_create

> Add variants to a product. The SKU goes inside `inventory_item`, not on the variant. When the product still carries its default placeholder variant, pass the strategy that removes it.

<div className="tool-route"><span className="tool-row-method" data-method="POST">POST</span><code>{"/admin/api/2026-07/graphql.json"}</code></div>
