I know that Shopify is pushing for GraphQL, but at the moment it’s not possible for us, so I have to rely on the deprecated Rest API documentation.
The problem is that the page regarding the product creation gives 404, as you can see trying to click “Product” from here: Metafield , that links to https://shopify.dev/docs/api/admin-rest/latest/resources/product but it does not work.
I understand that the Rest API is deprecated, but I still expected it to work at its fullest until discontinuation.
