I am struggling a bit with updating my product inventory on Shopify. I can update the variant inventory, but when I am updating all variants of a product at the same time, I would like to update it through a product update. When I read the doc, it seems to be possible, but it doesn't seems to work.
$shopify_product['product']['id'] = XXXXXXXXX;
// Each variants...
$shopify_product['product']['variants'][] = array(
'id' => $variant_shopify_id,
'inventory_quantity' => $quantity,
'old_inventory_quantity' => $quantity,
'inventory_management' => 'shopify',
);
That is what my codes looks like. It is similar to doc at this link: https://docs.shopify.com/api/product
Thanks a lot for your help,
Edouard
