The possible types of publication operations. ## Fields with this union * [Publication.operation](https://shopify.dev/docs/api/admin-graphql/2025-10/objects/Publication#field-Publication.fields.operation) OBJECT A group of [products](https://shopify.dev/docs/api/admin-graphql/latest/objects/Product) and [collections](https://shopify.dev/docs/api/admin-graphql/latest/objects/Collection) that are published to an app. Each publication manages which products and collections display on its associated [`Channel`](https://shopify.dev/docs/api/admin-graphql/latest/objects/Channel). Merchants can automatically publish products when they're created if [`autoPublish`](https://shopify.dev/docs/api/admin-graphql/latest/objects/Publication#field-Publication.fields.autoPublish) is enabled, or manually control publication through publication records. Publications support scheduled publishing through future publish dates for online store channels, allowing merchants to coordinate product launches and promotional campaigns. The [`catalog`](https://shopify.dev/docs/api/admin-graphql/latest/objects/Publication#field-Publication.fields.catalog) field links to pricing and availability rules specific to that publication's context. *** ```graphql union PublicationOperation = AddAllProductsOperation | CatalogCsvOperation | PublicationResourceOperation ```
