Shopify更新产品库存

Question

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

Answer 1

'inventory_quantity' => $quantity,'old_inventory_quantity' => $quantity will basically tell there is no difference in quantity change

The way it works is 'inventory_quantity' (minus) 'old_inventory_quantity'. In your case it is zero.

Try this instead 'inventory_quantity_adjustment' => $quantity - ('old_inventory_quantity') - This will add the required $quantity.
