Video Upload In Youtube APi using Javascript

Question

I need to upload video to youtube using APi.Is it possible in Youtube API?

Please give one example

Answer 1

This example is taken directly from the official YouTube Data API documentation, and shows how to perform the following functions:

1. It retrieves the channel name and thumbnail of the authenticated user's channel using the API's channels.list method.
2. It handles the video upload to YouTube using the resumable upload protocol.
3. It polls for the uploaded video's upload and processing status using the API's videos.list method by setting the part parameter value to status.

Using the Javascript Client API:
