Split shipment processing

A computer-implemented method, comprising:

• receiving, by a merchant computer, an indication to generate a split shipment authorization request for a split shipment of a plurality of split shipments associated with a single order;
• retrieving, by the merchant computer, previously-stored linking data that links the split shipment to the order, the linking data extracted from a previous split shipment authorization request associated with a previous split shipment of the plurality of split shipments associated with the order, wherein the linking data includes 1) validation data including a validation cryptogram based upon a total amount of the single order, and 2) a transaction ID;
• generating, by the merchant computer, the split shipment authorization request comprising a split shipment indicator, a split shipment amount associated with the split shipment, the total amount associated with the order, and the linking data;
• and
• transmitting, by the merchant computer, the split shipment authorization request to an authorization computer, wherein the authorization computer determines that the split shipment authorization request is associated with the split shipment using the split shipment indicator, and validates the split shipment authorization request by at least determining that the split shipment amount and at least a prior split shipment amount does not exceed the total amount in the split shipment authorization request, and also validating the validation cryptogram;
• and
• receiving, by the merchant computer, a split shipment authorization response from the authorization computer approving of the split shipment authorization request.

A computer system, comprising:

• a memory that stores computer-executable instructions;
• and
• a processor configured to access the memory and execute the computer-executable instructions to at least:
• receive, from a merchant computer, a split shipment authorization request comprising a split shipment indicator, a split shipment amount associated with a split shipment of a plurality of split shipments associated with a single order, a total amount associated with the order, and linking data configured to link the split shipment authorization request to a previously-authorized split shipment of the plurality of split shipments, wherein the linking data includes 1) validation data including a validation cryptogram based upon the total amount and 2) transaction ID, wherein the validation cryptogram was transmitted to the merchant computer, by the computer system, in response to a previous split shipment authorization request;
• validate the linking data by at least validating the validation cryptogram;
• generate a split shipment authorization response for the split shipment amount based at least in part on a validity of the linking data;
• and
• transmits the generated split shipment authorization response to the merchant computer.
