Receivable user_id with twitter OAuth API

[atasaki_auth_te]

Hi. I have a question about twitter OAuth API.

①Application ‘A’ is published oauth_consumer_key:123
②Application ‘B’ is published oauth_consumer_key:456
If same twitter_user logins application ‘A’ and ‘B’ with twitter OAuth API,
did it return same ‘user_id’ to the application ‘A’ and ‘B’?

Yes - the Twitter user_id is an immutable value for an individual user. However, the user authentication tokens returned in each case will be different, since they are specific to the combination of the user login, and the application consumer token.
