# Category field not available when using Python API library **URL:** \ **Category:** Tools\ **Tags:** Product-Tips, Setting-Up\ **Created:** [September 23, 2024, 8:22am UTC](https://community.shopify.com/t/category-field-not-available-when-using-python-api-library/360572 "2024-09-23T08:22:19Z")\ **Posts on this page:** 4\ **Page:** 1 ## AI-generated summary **Issue:** The `category` field is unavailable when using Shopify's Python REST API library, throwing an `AttributeError` when attempting to access `product[0].category`. **Root Cause:** The REST API does not support the `category` field. The Products REST API has been deprecated and will be discontinued next year. **Recommended Solution:** Migrate to GraphQL API, which supports product categories. **Follow-up Problems:** After switching to GraphQL: - First attempt using `productCreate` mutation with linked metafields returns error: "At least one value for the option linked to the 'shopify.size' metafield is invalid" - Second attempt following official documentation produces schema errors: fields `productCategory`, `productTaxonomyNodeId`, and `options` don't exist on types `UserError` and `ProductCreatePayload` **Status:** Unresolved. The user successfully identified the REST API limitation but encountered multiple GraphQL implementation errors, suggesting either API version mismatches or outdated documentation examples.

Hello, we are trying to update category and metafields using python API library but are unable to set category. Adding code and error we get below: ```auto api_version = '2024-07' with shopify.Session.temp(shop_url, api_version, 'hidden'):    product = shopify.Product.find()    print(product[0].category) --------------------------------------------------------------------------- AttributeError                            Traceback (most recent call last) in       3 #   print(single_image[0].src)       4    product = shopify.Product.find() ----> 5    print(product[0].category)       6   # product = shopify.Product()       7   # product.title = "Shopify Logo T-Shirt" c:\Users\root\AppData\Local\Programs\Python\Python37\lib\site-packages\pyactiveresource\activeresource.py in __getattr__ (self, name)     915             if name in self.attributes:     916                 return self.attributes[name] --> 917         raise AttributeError(name)     918     919     def __setattr__ (self, name, value): AttributeError: category ``` We can set other fields like title. Also, how would we set the values of attributes using python API library. For example: Attributes: - Age group: Adults - Clothing features: Wrinkle resistant - Color: Beige - Dress occasion: Formal - Dress style: Gown - Fabric: Satin - Neckline: Halter - Pattern: Solid - Size: One size - Skirt/Dress length type: Maxi - Sleeve length type: Sleeveless - Target gender: Female ---

Hi @aideveloper2 , I think the issue that you are having here is that the `category` field is not supported by the REST API. If you want to start using product categories you are going to need to migrate to GraphQL - [https://github.com/Shopify/shopify\_python\_api?tab=readme-ov-file#graphql](https://github.com/Shopify/shopify_python_api?tab=readme-ov-file#graphql). Its also worth mentioning that the Products REST API has been deprecated and will be going away next year - [https://shopify.dev/changelog/deprecation-timelines-related-to-new-graphql-product-apis](https://shopify.dev/changelog/deprecation-timelines-related-to-new-graphql-product-apis) ---

We did that but run into another issue. When we run this: ```markup mutation productCreate { productCreate(input: { title: "Linked option product test", category: "gid://shopify/TaxonomyCategory/aa-1-13-7", productOptions: [ { name: "Size", linkedMetafield: { namespace: "shopify", key: "size", values: [ "gid://shopify/Metaobject/43003248699", "gid://shopify/Metaobject/38602899515" ] } } ] }), { userErrors { message } product { id metafields(first: 10) { nodes { namespace key value } } options { name optionValues { name linkedMetafieldValue } } } } } ``` we get this: { “data”: { “productCreate”: { “userErrors”: [ { “message”: “At least one value for the option linked to the ‘shopify.size’ metafield is invalid” } ], “product”: null } }, “extensions”: { “cost”: { “requestedQueryCost”: 18, “actualQueryCost”: 10, “throttleStatus”: { “maximumAvailable”: 2000, “currentlyAvailable”: 1990, “restoreRate”: 100 } } } } ---

And if we try the code here: [https://shopify.dev/docs/apps/build/graphql/migrate/new-product-model/metafield-linked](https://shopify.dev/docs/apps/build/graphql/migrate/new-product-model/metafield-linked) we get another error / bug: { “errors”: [ { “message”: “Field ‘productCategory’ doesn’t exist on type ‘UserError’”, “locations”: [ { “line”: 6, “column”: 9 } ], “path”: [ “mutation CreateProductWithLinkedOptions”, “productCreate”, “userErrors”, “productCategory” ], “extensions”: { “code”: “undefinedField”, “typeName”: “UserError”, “fieldName”: “productCategory” } }, { “message”: “Field ‘productTaxonomyNodeId’ doesn’t exist on type ‘UserError’”, “locations”: [ { “line”: 11, “column”: 9 } ], “path”: [ “mutation CreateProductWithLinkedOptions”, “productCreate”, “userErrors”, “productTaxonomyNodeId” ], “extensions”: { “code”: “undefinedField”, “typeName”: “UserError”, “fieldName”: “productTaxonomyNodeId” } }, { “message”: “Field ‘options’ doesn’t exist on type ‘ProductCreatePayload’”, “locations”: [ { “line”: 13, “column”: 7 } ], “path”: [ “mutation CreateProductWithLinkedOptions”, “productCreate”, “options” ], “extensions”: { “code”: “undefinedField”, “typeName”: “ProductCreatePayload”, “fieldName”: “options” } } ] }
