# New validation against duplicate variant IDs in productSet mutation input

As of the **2024-07** version of the Admin GraphQL API, the `id` field in the [ProductVariantSetInput](https://shopify.dev/docs/api/admin-graphql/latest/input-objects/ProductVariantSetInput) will have validation to prevent duplicate values.

This enhancement ensures that there are no collisions when updating variants.
