When the events you have created are virtual meetings through the different video platforms available in TuCalendi, you need to include the link to the video room in the confirmation templates so your customers can access the video room once they have booked with you.
TuCalendi makes this very simple with the {video_link} substitution tag. Here's how you can do it.
Log in to TuCalendi with your username and password. Go to the "Email/SMS Templates" option.

In the "Confirmation templates" option, click on "Select":

If you have not created any confirmation template yet, click on the "New" button and enter the name you want to give the template you are going to create.
If you have already created a template and need to modify it, just click on the template you want to edit.

Initially the template will be empty so you can fully customize it. Click on the field called "DEFAULT":

Clicking on the "Email" field opens the editor, where you can write the booking confirmation notification and include the different replacement tags available.
Regardless of the video platform you have integrated in TuCalendi, for your customers to receive the link to the virtual meeting room, you must add the {video_link} tag. The link to the video room will then appear in the confirmation email they receive after booking with you, so they can access the meeting.

If you don't want the link to the video room to be displayed directly, you can include the {video_link} tag in a linked text.
To do this, just type the text you want, for example, "To access the video room click here". Select this text and click on the insert link option in the confirmation template editor:

In the URL field, enter the substitution tag {video_link} and click "Save".
The confirmation template will look like this:

When you finish customizing the confirmation template, click on "Save" and your customers will receive the confirmation email exactly the way you designed it.
