The request names no specific product, so these are candidates for a fulfillment API. Shopify exposes order fulfillment operations (get fulfillments, get a fulfillment, create a fulfillment event) 111, Billbee and API2Cart offer shipment-creation APIs for orders 919515, and Fulfillment.com offers an API to ship and list orders in a 3PL 616. Which platform or 3PL you fulfill through determines the right fit.
A question back: Which platform or 3PL do your orders come from, and do you need to create shipments, read fulfillments, or both?
