System and methods for application programming interface validation and testing

One or more non-transitory computer readable media storing computer executable instructions that, when executed by at least one processor, cause the at least one processor to perform a method of application programming interface (API) testing and validation, comprising:

• electronically receiving a plurality of payload response attribute data values associated with each of a plurality of executable code requests for a plurality of uniform resource network nodes;
• electronically generating a first virtual hash map comprising a mapping between each of the plurality of payload response attribute data values and each of the plurality of executable code requests;
• comparing the first virtual hash map to a second virtual hash map;
• and
• generating, based on the comparing, a testing report.

An apparatus comprising:

• one or more processors;
• and
• memory storing instructions that, when executed by the one or more processors, cause the apparatus to:
• electronically receive a plurality of payload response attribute data values associated with each of a plurality of executable code requests for a plurality of uniform resource network nodes;
• electronically parse the plurality of payload response attribute data values;
• and
• electronically generate a first virtual hash map comprising a mapping between each of the plurality of payload response attribute data values and each of the plurality of executable code requests.
