The disclosed embodiments include computer-implemented processes that determine, in real time, counterparty geolocation location based on structured messaging data, such as messaging data maintained within message fields of a request-for-payment (RFP) message compliant with the ISO 20022. For example, an apparatus may receive a RFP message that includes message data associated with a transaction involving first and second counterparties, and the RFP message may characterize a real-time payment requested from the second counterparty by the first counterparty. The apparatus may determine a geographic position of the first counterparty based the message data, and based on the first geographic position, transmit notification data to a device operable by the second counterparty. The notification data may cause the device to present digital content associated with at least one of the transaction, the first counterparty, or the second counterparty within a digital interface.
