The system automatically handles products that become unavailable after being added to the basket:

• On basket retrieval (GET /basket/), unavailable products are automatically removed

• Removed products are listed in unavailable_basket_products response field

• Includes product details and quantity that was removed

Unavailability Reasons:

• Product becomes inactive (is_active = false)

• Product type changes to non-purchasable (product_meta, grouped)

• Insufficient stock for requested quantity

• Product deleted from system

• Marketplace: Datasource becomes inactive or product mapping removed

Response Handling:

• unavailable_basket_products array contains removed items

• Each entry includes: pk, name, unavailable_quantity

• Promotional offers are recalculated without removed items

• Client should display notification about removed products
