YouTube makes you verify a channel before you can livestream to it with sidelineHD. If you've livestreamed to your channel before, these steps should not be necessary. If you're visual, here is a video to demo setup: YouTube Video - How to Create and Verify YouTube Channel
Creating and verifying a YouTube channel for livestreaming
I don’t have a YouTube channel. How do I get one?
Instructions for desktop and laptop users
Go to YouTube.com
Sign in via the button on the top right if necessary
Click on the profile avatar on the top right
Select “Create a channel”
Follow the steps provided by YouTube. Feel free to give your viewers as much or as little information as desired. Once completed, you should see “Your channel” in place of the “Create a channel” button from step 4.
Instructions for mobile users
NOTE: You can setup a YouTube Channel on Mobile but the final step of enabling livestreaming must be completed on a desktop or mobile.
Go to the YouTube mobile app
Sign in if necessary
Select the profile picture in the top right corner of the screen

I have a YouTube channel. Now what?
You will need to verify your channel for livestreaming if you’ve never streamed to it before.
*YouTube requires that you do following steps on a laptop or desktop computer*
Go to YouTube.com. Select the “Create” icon in the top right corner as shown below.
Select “Go live”
Select “ENABLE”
YouTube may ask you to verify your phone number. If necessary, follow those instructions by selecting “VERIFY”.
Go back to the YouTube tab you were working off of before and refresh the page. You should see the message below. That is good!
In 24 hours, go back to sidelineHD.com, go to the “Streaming” tab, and then select “Link YouTube”. Select the Google account that you made the channel with and “Allow” all permissions.
Hopefully this works and you see your YouTube channel on the sidelineHD streaming tab as shown below. If this does not work, please make sure that your 24 hours have passed. If you waited and still can’t get it, you can contact support by messaging sidelineHD’s Facebook page.
