[BUG] 403 Error when trying to download video from v16-webapp-prime.tiktok.com

[tonyquang]

Platform where the error occurred?

TikTok

The endpoint where the error occurred?

https://www.tiktok.com/api/post/item_list

Submitted input value?

I made a fetch_user_post request to the above tiktok api and got this response

After that I get the first one resp["video"]["bitrateInfo"][0]["PlayAddr"]["UrlList"][0] and try to download it, but I got 403 error ( I used the same header request which includes my cookies and user agent of fetch_user_post function but still get the same error)

So I tried to debug and realized that seems like a relationship between the device_id and my cookie (login already) if I use the default (hard-coded one) of the BaseRequestModel device_id: int = 7380187414842836523 then cannot download the video (403 access denied) but if I use my real device_id (get from browser) and with my cookie then I can access and download the video

Correct me if I am wrong thanks !

Yes, in an update of TikTok Web about half a year ago, they added this restriction. Your summary and analysis are very accurate. This restriction is associated with device_id, but the APP interface is still available, so I did not deal with this issue. However, we can discuss how to solve this problem elegantly. Thank you for your feedback and summary!

i found this endpoint that will return the wid in the response when we provide cookie and user-agent, I guess it is device_id
do you want take a look on it?
https://www.tiktok.com/api/v1/web-cookie-privacy/config?locale=en&appId=1988&theme=default&tea=1, we can get the device_id from user-agent and cookie in advance and store it somewhere for reusable
