Invalidate OAuth refresh token

[vic_m]

I have done the oauth flow with an app and get a refresh token. I implement some api calls using this refresh token to get a propper token and everything is working fine.

I want to invalidate my token so no more requests will work using this oauth token in my name. I have just removed my app integration on my spotify profile, but requesting data with my old previously linked with my app token is working fine and retrieving data when it shouldn't

How can I invalidate an oauth refresh token for my user so app cant request data anymore?
