In some examples, the process 700 may include one or more sub-operations of step/operation 606 of the process 600 in which the process 600 is configured to determine one or more validated and/or invalidated objects of an exchange request. For example, the process 700 may begin at step/operation 606 and end at step/operation 608.
In some embodiments, the process 700 includes, at step/operation 702, identifying one or more user attributes corresponding to the exchange request. For example, the exchange platform (e.g., a partner service, etc. thereof) may identify the one or more user attributes corresponding to the exchange request. In some examples, the exchange platform may maintain and/or have access to a plurality of system user data objects. Each system user data object may correspond to a user associated with a respective service provider instrument. In some examples, the exchange platform may identify the user attributes based at least in part on the service provider instrument, the exchange request, and/or the UUEK of the exchange request using the unique identifier mapping techniques described herein.
