Split shipment processing

Embodiments of the present invention are directed to methods, apparatuses, computer readable media and systems for obtaining authorization for a plurality of split shipments associated with a single order. In particular, embodiments of the present invention allow a merchant to submit a separate split shipment authorization request for each of the plurality of split shipments. The split shipments authorization requests are linked to the original order using verifiable linking data. The linking data may be extracted from a previous (e.g., initial) split shipment authorization request and/or a previous (e.g., initial) split shipment authorization request. The linking data may be validated by an authorizing entity (e.g., a payment processing network computer or an issuer computer) to ensure validity of a split shipment authorization request. Additionally, the split shipment authorization requests may be validated using one or more predefined split shipment rules.
