For YouTube videos to show on your campaign page, enter only the YouTube video ID — not the full URL.
For example, given this YouTube URL:
https://www.youtube.com/watch?v=wps_3k8Y2f8
The ID to enter is just the part after v=:
wps_3k8Y2f8
You must also link to a specific video, not a YouTube channel.
Find out how to update the YouTube ID for your campaign in this article.
Note: Videos will not work in a social media bio.
