How do I get the comments on a YouTube video with an API?

Send GET /v1/youtube/comments?id=VIDEO_ID with Authorization: Bearer YOUR_API_KEY. You can pass the 11-character ID or the full watch URL. Each comment comes back with its text, author, likes, reply count and a link that opens it on YouTube.
