So I have been getting youtube channel subscriber count with Youtube Data Api V3 for one channel. Right now I would like to get the live subscriber count of 50 YouTube channels.
Does Youtube allow sending a request with multiple channel ids? Or is there any approach that should be used to give live subscriber count for multiple channels with jQuery?
Example of what I'm looking for: https://www.youtube.com/watch?v=ftMnmPC82qM&ab_channel=MDM
Once you have your YouTube Data API v3 key then use Channels: list endpoint this way: https://www.googleapis.com/youtube/v3/channels?part=statistics&id=UCq-Fj5jknLsUf-MWSy4_brA,UCbCmjCuTUZos6Inko4u57UQ&key=YOUR_API_KEY then in the answer the field subscriberCount is what you are looking for.
You can add up to 50 YouTube channels ids in the id parameter.
Furthermore as pointed out by stvar the subscriberCounter is an approximation: https://stackoverflow.com/a/63537230
