Get email address from Twitter

What does it do?

Get email address from Twitter

Note: Further configuration is needed to enable fetching user emails through your Twitter App. Take a look at Twitter's doc for specifics.

The rule which makes the call to Twitter to retrieve the email is as follows. Do not forget to configure consumerKey and consumerSecretKey properly.

This rule will not persist the returned email to the Auth0 user profile, but will return it to your application.

If you want to persist the email, it will need to be done with appmetadata as described here:

For example, you can save it under app_metadata.social_email.

How do I use it?

Just create a new rule in the Auth0 dashboard, and copy the following code replacing the placeholders with the appropriate values.

What is Rule-Based Authentication?

A rule is arbitrary JavaScript code that can be used to extend Auth0s default behavior when authenticating a user. Enabled rules will be executed in the order shown below for all users and applications as the final step of the authentication process.

Rules can be used to enrich and transform the user profile, deny access to specific users under certain conditions, retrieve information from external services and much more. For more information about rules, please check the documentation
