Prerequisites

Medusa Components

It is assumed that you already have a Medusa backend installed and set up. If not, you can follow the quickstart guide to get started.

JS Client

This guide includes code snippets to send requests to your Medusa backend using Medusa’s JS Client, among other methods.

If you follow the JS Client code blocks, it’s assumed you already have Medusa’s JS Client installed and have created an instance of the client.

Medusa React

This guide also includes code snippets to send requests to your Medusa backend using Medusa React, among other methods.

If you follow the Medusa React code blocks, it's assumed you already have Medusa React installed and have used MedusaProvider higher in your component tree.

Authenticated Admin User

You must be an authenticated admin user before following along with the steps in the tutorial.

You can learn more about authenticating as an admin user in the API reference.

List Categories

You can retrieve available categories by sending a request to the List Categories endpoint:

• Medusa JS Client
• Medusa React
• Fetch API
• cURL

medusa.admin.productCategories.list()
.then(({ product_categories, limit, offset, count }) => {
  console.log(product_categories.length)
  // display categories
})

import { useAdminProductCategories } from "medusa-react"
import { ProductCategory } from "@medusajs/medusa"

function Categories() {
  const { 
    product_categories,
    isLoading } = useAdminProductCategories()

  return (
    <div>
      {isLoading && <span>Loading...</span>}
      {product_categories && !product_categories.length && (
        <span>No Categories</span>
      )}
      {product_categories && product_categories.length > 0 && (
        <ul>
          {product_categories.map(
            (category: ProductCategory) => (
              <li key={category.id}>{category.name}</li>
            )
          )}
        </ul>
      )}
    </div>
  )
}

export default Categories

fetch(`<BACKEND_URL>/admin/product-categories`, {
  credentials: "include",
})
.then((response) => response.json())
.then(({ product_categories, limit, offset, count }) => {
  console.log(product_categories.length)
  // display product categories
})

curl -L -X GET '<BACKEND_URL>/admin/product-categories' \
-H 'Authorization: Bearer <API_TOKEN>'

This request returns an array of product categories, as well as pagination fields.

You can also pass filters and other selection query parameters to the request. Check out the API reference for more details on available query parameters.

Create a Category

You can create a category by sending a request to the Create a Category endpoint:

• Medusa JS Client
• Medusa React
• Fetch API
• cURL

medusa.admin.productCategories.create({
  name: "Skinny Jeans",
})
.then(({ product_category }) => {
  console.log(product_category.id)
})

import { useAdminCreateProductCategory } from "medusa-react"

const CreateCategory = () => {
  const createCategory = useAdminCreateProductCategory()
  // ...

  const handleCreate = () => {
    createCategory.mutate({
      name: "Skinny Jeans",
    })
  }

  // ...
}

export default CreateCategory

fetch(`<BACKEND_URL>/admin/product-categories`, {
  credentials: "include",
  method: "POST",
  headers: {
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    name: "Skinny Jeans",
  }),
})

  console.log(product_category.id)
})

curl -L -X POST '<BACKEND_URL>/admin/product-categories' \
-H 'Authorization: Bearer <API_TOKEN>' \
-H 'Content-Type: application/json' \
--data-raw '{
    "name": "Skinny Jeans"
}'

This request requires one body parameter name, which is the name of the category. The request also accepts the following optional body parameters:

• handle: a string that is typically used as a URL path or slug. If you don’t provide a handle, it will be the kebab case format of the name.

Manage Products in a Category

You can manage the categories of each product individually using the product APIs. This section explores the other approach of managing a product’s category using the product category APIs.

Add Products to a Category

You can add more than one product to a category using the Add Products to a Category endpoint:

• Medusa JS Client
• Medusa React
• Fetch API
• cURL

medusa.admin.productCategories.addProducts(productCategoryId, {
  product_ids: [
    {
      id: productId1,
    },
    {
      id: productId2,
    },
  ],
})
.then(({ product_category }) => {
  console.log(product_category.id)
})

import { useAdminAddProductsToCategory } from "medusa-react"

const UpdateProductsInCategory = () => {
  const addProductsToCategory = useAdminAddProductsToCategory(
    productCategoryId
  )
  // ...

  const handleAdd = () => {
    addProductsToCategory.mutate({
      product_ids: [
        {
          id: productId1,
        },
        {
          id: productId2,
        },
      ],
    })
  }

  // ...
}

export default UpdateProductsInCategory

fetch(`<BACKEND_URL>/admin/product-categories/${productCategoryId}/products/batch`, {
  credentials: "include",
  method: "POST",
  headers: {
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    product_ids: [
      {
        id: productId1,
      },
      {
        id: productId2,
      },
    ],
  }),
})
.then((response) => response.json())
.then(({ product_category }) => {
  console.log(product_category.id)
})

curl -L -X POST '<BACKEND_URL>/admin/product-categories/<CAT_ID>/products/batch' \
-H 'Authorization: Bearer <API_TOKEN>' \
-H 'Content-Type: application/json' \
--data-raw '{
  "product_ids": [
    {
      "id": "productId1"
    },
    {
      "id": "productId2"
    }
  ]
}'

This request requires the ID of the category to be passed as a path parameter.

In its body, it requires a product_ids parameter which is an array of objects. Each object in the array has the property id, which is the ID of the product to add. So, each product you want to add you pass it to the array as an object having the property id.

The request returns the full object of the product category updated with the new products.

Remove Products from a Category

You can remove products from a category by sending a request to the Delete Products endpoint:

• Medusa JS Client
• Medusa React
• Fetch API
• cURL

medusa.admin.productCategories.removeProducts(
  productCategoryId,
  {
    product_ids: [
      {
        id: productId1,
      },
      {
        id: productId2,
      },
    ],
  }
)
.then(({ product_category }) => {
  console.log(product_category.id)
})

import { 
  useAdminDeleteProductsFromCategory,
} from "medusa-react"

const DeleteProductsFromCategory = () => {
  const deleteProductsFromCategory = 
    useAdminDeleteProductsFromCategory(productCategoryId)
  // ...

  const handleDelete = () => {
    deleteProductsFromCategory.mutate({
      product_ids: [
        {
          id: productId1,
        },
        {
          id: productId2,
        },
      ],
    })
  }

  // ...
}

export default DeleteProductsFromCategory

fetch(`<BACKEND_URL>/admin/product-categories/${productCategoryId}/products/batch`, {
  credentials: "include",
  method: "DELETE",
  headers: {
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    product_ids: [
      {
        id: productId1,
      },
      {
        id: productId2,
      },
    ],
  }),
})
.then((response) => response.json())
.then(({ product_category }) => {
  console.log(product_category.id)
})

curl -L -X DELETE '<BACKEND_URL>/admin/product-categories/<CAT_ID>/products/batch' \
-H 'Authorization: Bearer <API_TOKEN>' \
-H 'Content-Type: application/json' \
--data-raw '{
  "product_ids": [
    {
      "id": "productId1"
    },
    {
      "id": "productId2"
    }
  ]
}'

This request requires the ID of the category to be passed as a path parameter.

In its body, it requires a product_ids parameter which is an array of objects. Each object in the array has the property id, which is the ID of the product to remove. So, each product you want to remove you pass it to the array as an object having the property id.

The request returns the full object of the product category updated with the its products.
