You need to go to your Lodago account in the "Calendar/Email integration & Booking links" tab.
You will find an infinite number of booking links and for each of these links, you can define in one click the duration of the proposed appointment and if this link offers video-conference appointments. You can then simply copy the link and place it on your website.
This appointment link will redirect your prospect to a personalised page with your updated calendar and availability to make an appointment.
