I have searched for many days now, but didn't found a field in the TikTok API where I can get the username of the user that has connected his TikTok account with my website. I want to let user log in with their TikTok account to let them link it from my website to TikTok and want to display their "@" name (not the display name. I can only get their IDs etc. but no their username. If anyone can help I'd be very happy!

I searched on many forums for this but didn't sound any solution. I'm expecting to be able to send a request to the official TikTok API which then replies the username of someones ID or of someones Token I own.

On Get User Info API route you can put username on fields arguments like this :

https://open.tiktokapis.com/v2/user/info/?fields=profile_deep_link,username

This field username is not documented (maybe a mistake in TikTok side) but it work well for me, you can see the screenshot : enter image description here

As the TikTok API only provides the display name, the only workaround we have found so far is to fetch the videos of your user, and parse the share-url to extract the username from the first video. You just have to pray that he has got at least one.

Query the videos of your user:

curl -L -X POST 'https://open.tiktokapis.com/v2/video/list/?fields=share_url' -H 'Authorization: Bearer XXXXX' \ -H 'Content-Type: application/json' \ --data-raw '{ "max_count": 1 }'

Here, the token you provide tells the API which user you are talking about.

The share-url looks like this: https://www.tiktok.com/@USERNAME/video/VIDEO-ID?utm_campaign=tt2d_open_api&utm_source=aaaa
