Your booking/API password is included in your booking confirmation email sent to you when the booking was made, and is located about half way down with your booking reference number under the heading "Need to change something".
If you have not received this, first check that your email service didn't move it to your spam or junk folder.
If you have lost or are unable to locate your booking password you can call our Contact Centre team to request it be re-sent to your email address.
