t = api.byUsername('therock', did=did, custom_verifyFp='your_verify_fp')[0]
print(t)
v_bytes = api.get_Video_By_TikTok(t, did=did, custom_verifyFp='your_verify_fp')

TikTok had add verrification in web. You need verrifyFp to get data.

[JohnTYH]

Hmm, could you give me an example of how to include the verifyFp? Ive been looking through this repo but im still not sure...

[thanhnguyen1121]

I don't know how to get it in python. But when I decode tiktok in web after confirming, I get an api like this: "https://www.tiktok.com/node/share/user/@your_tiktok_username?verifyFp=verify_khwsg04i_Kjx9V5Ev_u6d2_4UiG_8p2n_LAsK5DB"

I logged into TikTok on chrome and then got the s_v_web_id value in cookies (on chrome go into settings, see all cookies, and you can find the s_v_web_id value there it just a long string like verify_*********...). I used that in for custom_verifyFp="", but still keep getting the same exact JSON error, my same code worked a few weeks ago so I assume I'm doing something wrong with the way I'm using verifyFp, but idk...

[KennBro]

Same

Not bad idea, I'll try it

[davidteather]

Yeah the verifyFp you can view as a parameter on API calls or the cookie called s_v_web_id package got changed a few times up until now and may be working more consistently now

you could instantiate TikTokApi object with the custom_verifyFp='yourcookievalue'
api = TikTokApi(custom_verifyFp='yourcookievalue')

[rtheodoro]

@viniciusao do you know how to make it work?
