Required permission: write_products

Create a lot for a product ahead of receiving, so the dock can select it instead of typing it in. Only organization API keys can create lots, and the product must require lot tracking. Send lot_number, expiration_date, or both; sent alone, expiration_date creates an expiration-only lot.

To lock an inbound shipment item to a lot, pass the lot's ID as product_lot_id on the item, or send lot_number and expiration_date on the item to find or create the lot in one call.
