We have introduced a new endpoint Delete product variant parameter. This call deletes the parameter and all its values from the eshop. It is not possible to delete a parameter used in product variant – in such case error code 409 is returned.
To delete just one value of a variant parameter, use Delete product variant parameter value – the value is identified by key rawValue. It the value is used in any product variant in the eshop, deletion is not possible and error code 409 is returned.
