Video Translation (HeyGen)

Translate and dub existing videos into multiple languages, preserving lip-sync and natural speech patterns. Provide a video URL or HeyGen video ID — no need to create the video on HeyGen first.

Authentication

All requests require the X-Api-Key header. Set the HEYGEN_API_KEY environment variable.

curl -X POST "https://api.heygen.com/v2/video_translate" \
  -H "X-Api-Key: $HEYGEN_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"video_url": "https://example.com/video.mp4", "output_language": "es-ES"}'

Default Workflow

1. Provide a video URL or HeyGen video ID
2. Call POST /v2/video_translate with the target language
