I need the API URL for Youtube Related Videos using the Youtube V3 API. But I couldn't find the direct API call, like it is in Version 2. Did I miss something?
Are you trying to find videos related to a video?
You can use search->list call for this with specifying the "relatedToVideoId"
And for anyone looking for a coded example:
GET https://www.googleapis.com/youtube/v3/search?part=snippet&relatedToVideoId=5rOiW_xY-kc&type=video&key={YOUR_API_KEY}
