KTX Macro is a Chrome extension that automates the process of booking sold-out KTX train tickets. With this extension, users can easily secure their desired train tickets without the hassle of constantly checking for availability. The latest update added a feature for joining the reservation waiting list, ensuring users have more chances of getting their preferred tickets.

The extension works by automatically navigating the Let's Korail website, logging in, and selecting the desired date and time for the train journey. Users can then choose the specific train they want to book and start the automated reservation process with just a click of a button. Once the reservation is successful, a trumpet sound is played, and users are redirected to the payment screen.

Additionally, KTX Macro offers the option to receive notification messages via Telegram when a reservation is completed. Users can easily configure this feature by clicking on the extension icon and providing the necessary Telegram bot token and chat ID.

It is important to note that users should have their speakers turned on to hear the reservation confirmation sound, and they are advised to complete the payment within 20 minutes after a successful reservation.

Overall, KTX Macro is a convenient and time-saving tool for those who frequently travel by KTX trains and want to secure their tickets effortlessly.
