Custom Categories

Read more in guide Working with Custom Categories.

These are examples of queries to fetch custom category taxonomy data.

Taxonomies unmapped to the schema

Retrieve categories with taxonomy "product-category":

query {
  categories(taxonomy: "product-category") {
    __typename
 
    ...on Category {
      count
      description
      id
      name
      slug
      url
    }
    
    ...on GenericCategory {
      taxonomy   
      customPostCount
      customPosts {
        __typename
        ...on CustomPost {
          id
          title
        }
      }
    }
  }
}

Retrieving categories associated to a custom post

Type GenericCustomPost has field categories, to retrieve the custom categories added to the custom post:

query {
  customPosts(
    filter: { customPostTypes: "product" }
  ) {
    __typename
 
    ... on GenericCustomPost {
      categories(taxonomy: "product-cat") {
        __typename
        id
        name
        taxonomy
      }
    }
  }
}

Filtering custom posts by category

To retrieve the custom posts with given categories, we can use input filter.categories:

query {
  customPostsByCatIDs: customPosts(
    filter: {
      categories: {
        includeBy: {
          ids: [26, 28]
        }
        taxonomy: "product-cat"
      }
    }
  ) {
    id
    title
  }
 
  customPostsByCatSlugs: customPosts(
    filter: {
      categories: {
        includeBy: {
          slugs: ["news", "sports"]
        }
        taxonomy: "product-cat"
      }
    }
  ) {
    id
    title
  }
}

Setting categories on a custom post

Mutation:

mutation {
  setCategoriesOnCustomPost(
    input: {
      id: 1499, 
      categoryIDs: [2, 5]
      taxonomy: "cat-taxonomy"
    }
  ) {
    status
    errors {
      __typename
      ... on ErrorPayload {
        message
      }
    }
    customPostID
    customPost {
      categories(taxonomy: "cat-taxonomy") {
        id
      }
      categoryNames(taxonomy: "cat-taxonomy")
    }
  }
}

Nested mutation:

mutation {
  customPost(by: { id: 1499 }) {
    setCategories(
      input: {
        categoryIDs: [2, 5]
        taxonomy: "cat-taxonomy"
      }
    ) {
      status
      errors {
        __typename
        ... on ErrorPayload {
          message
        }
      }
      customPostID
      customPost {
        categories(taxonomy: "cat-taxonomy") {
          id
        }
        categoryNames(taxonomy: "cat-taxonomy")
      }
    }
  }
}

Creating, updating and deleting a custom category

This query creates, updates and deletes category terms for a custom some-cat-taxonomy category:

mutation CreateUpdateDeleteCategories {
  createCategory(input: {
    taxonomy: "some-cat-taxonomy",
    name: "Some name"
    slug: "Some slug"
    description: "Some description"
  }) {
    status
    errors {
      __typename
      ...on ErrorPayload {
        message
      }
    }
    category {
      ...CategoryData
    }
  }
 
  updateCategory(input: {
    id: 1
    taxonomy: "some-cat-taxonomy"
    name: "Some updated name"
    slug: "Some updated slug"
    description: "Some updated description"
  }) {
    status
    errors {
      __typename
      ...on ErrorPayload {
        message
      }
    }
    category {
      ...CategoryData
    }
  }
 
  deleteCategory(input: {
    id: 1
    taxonomy: "some-cat-taxonomy"
  }) {
    status
    errors {
      __typename
      ...on ErrorPayload {
        message
      }
    }
  }
}
 
fragment CategoryData on Category {
  id
  name
  slug
  description
  parent {
    id
  }
}
