N8N Tools - YouTube Enhanced

Comprehensive YouTube Data API v3 and Analytics integration for N8N workflows

Actions83

Overview

The "Download Caption" operation in the Captions resource of this YouTube Enhanced node allows users to download caption data associated with a specific caption ID from YouTube. This is useful for workflows that need to retrieve subtitle or closed caption files for videos, such as for translation, editing, archiving, or accessibility purposes.

Practical examples include:

  • Automatically downloading captions for videos to generate transcripts.
  • Integrating caption downloads into content localization workflows.
  • Archiving captions alongside video metadata for compliance or record-keeping.

Properties

Name Meaning
Caption ID The unique identifier of the caption to download.

Output

The output JSON contains the downloaded caption data corresponding to the specified Caption ID. The exact structure depends on the YouTube API response but typically includes caption text and metadata.

If the node supports binary data output for captions (e.g., subtitle files), it would represent the caption file content in binary form; however, based on static analysis, this node returns the caption data in JSON format.

Dependencies

  • Requires an active subscription and valid API key credential for the external N8N Tools API service.
  • Requires OAuth2 credentials for YouTube API access.
  • The node internally uses a specialized Captions API helper class to interact with YouTube's captions endpoints.

Troubleshooting

  • Invalid API Key or Subscription: If the node throws an error about invalid subscription or API key, verify that the provided API key credential is correct and active.
  • Caption Not Found: If the Caption ID does not exist or is incorrect, the YouTube API may return an error. Ensure the Caption ID is valid and accessible by the authenticated user.
  • Permission Issues: The OAuth2 credentials must have sufficient permissions to access captions for the target video.
  • Network or API Errors: Transient network issues or quota limits on the YouTube API can cause failures. Retry or check API usage limits.
