Systems, methods, and computer-readable media are provided for verifying parameters for a user-created event. In accordance with one implementation, a computer-implemented method is provided that comprises receiving a set of parameters for an event created by a user. Further, the method includes verifying the set of parameters for the event by comparing the set of parameters to source data and determining, based on a result of the verification, replacement data for one or more of the set of parameters for the event. The method also includes presenting, on a display device, the replacement data for selection by the user and updating, based on a selection received from the user, the set of parameters for the event to include the replacement data.
