Unable to update Shopify product category via GraphQL productSet mutation

Hey @clothovia :waving_hand: - as of API version 2024-04, ProductTaxonomyNode was replaced with TaxonomyCategory (there’s a bit more info on this here). In your mutation you’d want to use something like this:

{
  "input": {
    "id": "gid://shopify/Product/YOUR_PRODUCT_ID",
    "category": "gid://shopify/TaxonomyCategory/vp-2-3"
  }
}

The category IDs from the site here should be accurate though, but they have changed slightly (I don’t believe that Node ID you used is accurate as of 2024-04)

Hope this helps - let me know if I can clarify anything on our end!
