# New validation against duplicate handles in productCreate, productUpdate, and productSet mutation inputs

As of the `2025-01` version of the Admin GraphQL API, the `handle` field in [productInput](https://shopify.dev/docs/api/admin-graphql/latest/input-objects/ProductInput) for [productCreate](https://shopify.dev/docs/api/admin-graphql/latest/mutations/productCreate) and [productUpdate](https://shopify.dev/docs/api/admin-graphql/latest/mutations/productUpdate), as well as in [productSetInput](https://shopify.dev/docs/api/admin-graphql/latest/input-objects/ProductSetInput) for [productSet](https://shopify.dev/docs/api/admin-graphql/latest/mutations/productSet) will be validated for uniqueness. This means that you will no longer be able to input a duplicate handle. This change does not affect existing behaviour when `handle` is not provided as input.

This enhancement ensures that there are no collisions when creating or updating product handles.
