Update user profile identity in Firebase

How it works?

This rule is used to create or update identity information for a user profile stored in Firebase using the Firebase REST API. The unique user.user_id is base64 encoded to provide a unique generated key for the user.

Each time the user logs into the system, properties of their user profile can updated in Firebase to keep identity properties (like name, email, etc) in sync with authentication credentials.

You can find more information in the Firebase API: REST API

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.

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 theauthentication 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. To learn more about rules, see Auth doc Rules
