Send video to TikTok servers

Note: If you used the source=PULL_FROM_URL to initialize the video upload, you can skip this part. The TikTok server will handle the video uploading process for you.

Once you have initialized the video upload and received an upload_url, you must send the video file to TikTok for processing. Many video formats are supported and chunking is provided for larger files. Learn more about media transmission here.

HTTP URL	Returned in `upload_url`
HTTP Method	PUT

Important: Use the entire URL returned as the upload_url including the returned query parameters.
