Twitter

Overview

This API has been available since 1.1.0

The Twitter identity provider type will use the Twitter OAuth v1.0 login API. it will provide a Login with Twitter button on FusionAuth’s login page that will leverage the Twitter login page directly. Additionally, this identity provider will call Twitter’s /1.1/account/verify_credentials.json API to load additional details about the user and store them in FusionAuth.

The email address returned by Twitter will be used to create or lookup the existing user. Additional claims returned by Twitter can be used to reconcile the User to FusionAuth by using a Twitter Reconcile Lambda. Unless you assign a reconcile lambda to this provider, on the email address will be used from the available claims returned by Twitter.

Twitter does not require a user to have an email address. However, to prevent account hijacking and take-over, FusionAuth prevents users from logging in with Twitter unless they have setup an email address in their Twitter account. Keep this in mind as you enable this identity provider.

FusionAuth will also store the Twitter access token returned from the OAuth v1.0 login workflow in the identityProviderLink object, in the identityProviderLink.token field. This object is accessible using the Link API.

The identityProviderLink object stores the token so that you can use it in your application to call Twitter APIs on behalf of the user if desired.

Prior to version 1.28.0, the token was stored in the UserRegistration object, in the tokens Map.
