Im working on api integration between one store of magento2 multi store installation and product db of a client. Our current problem is that part of the items for in our store are duplicated (same sku) with different shops. Which by itself is fine and expected. But we would like to be sure that parent products (eg form default view) are never overwriting our values. Right now this works fine for all values that are set for the product.
Problem starts when for example we create product A for shop TEST_SHOP which is new for the shop and installation, with no description, then 3rd party also adds product A for default view with description. Then our product automatically gets description form new update.
As far as I understand this is caused by use default value check box (it is checked by default for empty values). Can this check box be unchecked from API ?
