When your cardholders inform you of their travel plans (e.g. via an online form or your call center), you can send those travel details to Visa using the Visa Travel Notification API. Visa then stores the travel itineraries for use when your cardholders makes purchases while travelling. When your cardholder transacts, Visa analyzes whether the transaction is located near the travel destination and during the travel dates you sent to Visa. Based on this analysis, Visa sends you an enhanced Visa Advanced Authorization Score and populates the Visa Travel Authorization Tag in the authorization message so you can use them in your decision of whether or not to approve a transaction.
Note: The Visa Travel Notification Service only impacts the Visa Advanced Authorization score if you are an issuer in the United States or Canada.
Since Visa Travel Notification Service is API based, you can send travel details to Visa regardless of how your cardholders tell you their plans. For example, if you have an online or mobile form that cardholders can enter their travel plans into, you can send the cardholder-reported plan to the Visa Travel Notification API. If your cardholder calls your customer service center, your customer service backend system can send the cardholder-reported travel plan to the Visa Travel Notification API.
