HI Aaron Koo,
Thank you for your purchase.

Yes you can use hooks like beforeConfirmedBooking that will be triggered when your customers confirm booking. You can set that redirect URL that you need like on this script(we use https://www.google.com as example, but you will replace this with your own URL)

<script>
window.beforeConfirmedBooking = function()
{
window.location.href = "https://www.google.com";
};
</script>

Please insert this script on page where you insert Amelia shortcode.

Best regards.

Hi Aaron,

Before the booking is confirmed by the customer the script will automatically be triggered.

This line of code will be executed ( based on the script below ) 

window.location.href = "https://www.google.com";

You can also use  this afterConfirmBooking instead of beforeConfirmedBooking

Best regards.
