Update product attributes by SKU

Product attributes are the objective and factual descriptions of products that shoppers see when they browse through an e-commerce platform. Attributes may be technical specifications like size, weight, etc., design specifications like color, material, etc., or basic specifications such as name, description, ID, etc.

This endpoint is used to update product attributes, completely replacing the existing ones.

1. This is recommended over PATCH /products/sku/{sku}/attributes, if the update involves replacing all the attributes. If there are any missing or null fields in the request, the original values will be replaced with empty ones.
2. If you don't have product SKU, use the corresponding ID-based endpoint - PUT /products/{id}/attributes.
