How to revoke an access token? (Other answers suggest security page, but doesn't appear there)

[Cross-linking for reference: https://stackoverflow.com/questions/43705630/how-do-i-revoke-generated-access-tokens-for-dropbox-applications ]

a) The Dropbox web site/API don't offer a way to list individual access tokens.

b) There are several ways to revoke access tokens.

• The user can revoke all access tokens for an app via the account security page by clicking the 'x' at the right of the app's row. This will revoke all access tokens for that app-user pair though, and doesn't offer a way to revoke specific/individual ones.
• If the app uses the "app folder" permission, the user can delete the app folder itself, which will cause any further API calls for that app-user pair to fail.
• The app can revoke individual access tokens using the /2/auth/token/revoke API endpoint. That will revoke only the individual access token used to make the call itself. You can use it multiple times to revoke any/all access tokens you have.
