# Transcript

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

{% hint style="warning" %}
Transcripts are separate from subtitles and closed captions (CC). To extract subtitles and closed captions, use the [YouTube Subtitles](https://developers.oxylabs.io/scraping-solutions/web-scraper-api/targets/youtube/youtube-subtitles) source.
{% endhint %}

## Request samples

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