The first step here is to activate your YouTube Live account. Please note, activation takes 24 hours to be effective.
Here is the link to activate your YouTube Live account.
Once your Live account is activated, click on the camera icon, on the right side of the webpage header.

Then, click on "Go live"
You will arrive in the Youtube Studio, which asks you to first edit the Webcam stream information. Here, you have to choose the title of your stream. We recommend choosing "Unlisted" to avoid any external entrance.
Creating a stream allows you to prepare the stream in advance and set it up with your streaming tool.
You can also upload a custom thumbnail. This is the still image attendees while see before & after the streaming session.
Once the settings are defined, click on "Create Stream" & here you go! Your stream is ready to be integrated into your Swapcard session.
In the "Manage" section, click on the three little dots next to the chosen section, and click on "Get shareable link"
You will then use the alphanumeric code which is you video ID. You will need to copy that and paste it into Swapcard in the "video streaming" section of your session.
