Dynamic virtual identifier generation for user interaction authorization verification and logging

A non-transitory computer-readable medium storing computer-executable instructions that, when executed, cause a computing system to perform operations comprising:

• detecting, by an interaction authorization system, a trigger event representing an action taken by a user for which the user will incur expenses on a credit card to be reimbursed by a networked entity associated with the interaction authorization system;
• responsive to detecting the trigger event, transmitting, by the interaction authorization system, a card token request to an account management system for the credit card based on the trigger event;
• receiving, by the interaction authorization system, a card token from the account management system, wherein the card token comprises a string of characters for identifying the credit card of the networked entity;
• associating, by the interaction authorization system, the card token with the trigger event in a database;
• receiving, by the interaction authorization system, interaction information describing a transaction for which the credit card was used to authorize the transaction, wherein the interaction information includes the card token;
• associating, by the interaction authorization system, the transaction with the trigger event based on the interaction information;
• generating, by the interaction authorization system, an interaction log describing the transaction, wherein the interaction log associates the transaction with the trigger event;
• and
• applying expense management rules to the transaction based on the association of the card token with the user in the database.
