In Auth0 console I can see last_ip field for all my users, however when I make a request with id_token to /tokeninfo API the response JSON object doesn’t have last_ip information. All of the other fields show up in the JSON (nickname, locale, email, picture, updated_at, app_metadata…).
Is there a way to get last_ip value with a /tokeninfo call?
The last_ip field is not returned as part of the /tokeninfo endpoint nor, if I recall correctly, as part of the /userinfo endpoint.
However, you should be able to obtain that information if you have a client application suitable to call the Management API (see this docs page about how to obtain a Management API token). In this situation should be able to obtain that field.
