So I'm looking to enable users to link their tiktok account to their account on my website using oauth. Sadly I can't directly sign them in with tiktok due to supabase not supporting tiktok oauth.

So, I'm looking for any good resources to learn how to connect third party apps using oauth. I assume I'll have to get some unique identifier from tiktok after the sign in, and then save that in the database, linked to the users account?

But I want to go about it securely, and dont know enough to do so right now. Anyone know any good resources/have some good advice? Thanks!
