# Publication Id and channel Id validations

As of the 2023-04 version of the Admin GraphQL API, the `publicationId` and `channelId` fields of the `PublicationInput` will be validated on calls to `publishableUnpublish` and `productUnpublish` mutations.

This allows you to ensure that ids sent into a mutation correspond to existing records in the database.

The validation message for the `publicationId` field will change from "Channel can't be blank" to "Publication does not exist" on a `PublicationInput` object.

Learn more about [publishableUnpublish](https://shopify.dev/api/admin-graphql/2022-04/mutations/publishableUnpublish) and [productUnpublish](https://shopify.dev/api/admin-graphql/2022-04/mutations/productUnpublish) on [Shopify.dev](https://shopify.dev/).
