Use audio from a TikTok or Instagram link in your video

Paste a public TikTok or Instagram URL into POST /v1/media-imports, detach the audio with POST /v1/audio-detach, then use the resulting file as soundtrack or audio.url in a Timeline 1.0 render. Any other host, YouTube included, is rejected with unsupported_platform.

OpusClip's September 30 changelog entry describes the same idea inside an editor: drop in a file or paste a link and the audio is pulled out. This post is the API version of that chain, from the Sume docs and OpenAPI file read 2026-10-01.

Which links does the import accept?

The OpenAPI description for submitMediaImportJob says it imports a public TikTok or Instagram video URL into Sume-owned storage, and that YouTube and other hosts are rejected with unsupported_platform. The request body requires only url. The result is a file on media.sume.com, which is the only kind of source the other audio tools read.

If your link is to a private account or a non-video page, treat it as unsupported; the schema describes public video or reel URLs. For the Instagram side of this, see Instagram reel download API.

How do I turn the imported video into an audio file?

Send the imported media.sume.com URL as video_url to audio detach. The format field is wav (default, pcm_s16le, sample-exact) or mp3 (128 kbps), and an optional range takes { start, end? } in seconds so you keep only the part you want. Detach needs an Idempotency-Key, and a source with no audio track fails with detach_source_has_no_audio. The full walk-through is in extract audio from a video URL.

How do I use that audio under my video?

Pass the detached audio_url to Timeline 1.0. As a soundtrack it is an optional bed with url, gain_db, loop, fade_out_seconds (up to 10) and duck_db. As audio.url it becomes the single spine that sets the render's audio.

What should I check before using someone else's audio?

Importing a public URL does not tell you whether you may reuse the sound in your own video. Rights to the track are your call; check the source's terms before publishing. For a bed you control, see mix voice with background music.
