Processing fulfillment using stateless APIs and complex classes

An apparatus for data processing, comprising:

• a processor,
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive, at a user interface, a configuration of a plurality of components corresponding to one or more fulfillment rules defining a fulfillment allocation process for an order request, wherein the one or more fulfillment rules are configured to identify at least one fulfillment center of a plurality of fulfillment centers;
• receive, via a stateless web resource application programing interface (API), the order request, wherein the order request specifies one or more order parameters and indicates an invocable action;
• generate, according to the invocable action indicated by the order request, an instance of a complex object representing the order request, wherein the complex object includes one or more nested data types corresponding to the one or more order parameters and wherein the invocable action is configured to expose the one or more nested data types to the fulfillment allocation process defined by the one or more fulfillment rules;
• store, in accordance with the invocable action, the generated instance of the complex object representing the order request in an object storage system for processing to generate a response based on the one or more fulfillment rules;
• process, based at least in part on the invocable action exposing the one or more nested data types, the instance of the complex object stored in the object storage system according to the one or more fulfillment rules wherein the processing results in an identification of a fulfillment center of the plurality of fulfillment centers using the one or more order parameters included in the order request;
• and
• generate the response to the order request based at least in part on the processing of the instance of the complex object, wherein the response includes at least an indication of the fulfillment center.

A non-transitory computer-readable medium storing code for data processing, the code comprising instructions executable by a processor to:

• receive, at a user interface, a configuration of a plurality of components corresponding to one or more fulfillment rules defining a fulfillment allocation process for an order request, wherein the one or more fulfillment rules are configured to identify at least one fulfillment center of a plurality of fulfillment centers;
• receive, via a stateless web resource application programing interface (API), the order request, wherein the order request specifies one or more order parameters and indicates an invocable action;
• generate, according to the invocable action indicated by the order request, an instance of a complex object representing the order request, wherein the complex object includes one or more nested data types corresponding to the one or more order parameters and wherein the invocable action is configured to expose the one or more nested data types to the fulfillment allocation process defined by the one or more fulfillment rules;
• store, in accordance with the invocable action, the generated instance of the complex object representing the order request in an object storage system for processing to generate a response based on the one or more fulfillment rules;
• process, based at least in part on the invocable action exposing the one or more nested data types, the instance of the complex object stored in the object storage system according to the one or more fulfillment rules wherein the processing results in an identification of a fulfillment center of the plurality of fulfillment centers using the one or more order parameters included in the order request;
• and
• generate the response to the order request based at least in part on the processing of the instance of the complex object, wherein the response includes at least an indication of the fulfillment center.
