With 5MinutesAPI, the bank instantly dispatches a secure WhatsApp template: "Did you authorize a payment of $450 at Apple Store?" with two Quick Reply buttons: [Yes, I did] and [No, Freeze Card].
Because WhatsApp works over Wi-Fi, the traveler receives the alert instantly. Our high-speed Golang infrastructure ensures the webhook response is routed back to the bank's core banking system in milliseconds, unfreezing the card without human intervention.
