YouTube Transcript

Learn how to scrape transcripts from YouTube videos using Web Scraper API. Find out more about its parameters and practical examples.

You can get YouTube video transcripts by providing a YouTube video ID and a language_code to the youtube_transcript source.

Transcripts are separate from subtitles and closed captions (CC). To extract subtitles and closed captions, use the YouTube Subtitles source.

The following examples demonstrate how to retrieve the English transcript of a YouTube video, specifically when the transcript was provided by the uploader.
