Ans: In the RegistrationHandler interface, Salesforce offers the option of single sign-on using an authentication service, such as Facebook or Janrain, into Salesforce.
It has the namespace of Auth.
Property | Туре | Description | Required or Optional | Available Version |
Audience with the Permission criterion type | ||||
ProfileId | String | Profile ID of a user. | Required if creating or updating an audience with the Profile criterion type | 48.0 |
Subdivision | String | Subdivision of a user. | Required if creating or updating an audience with the GeoLocation criterion type and using the city property | 48.0 |
Ans: Below are some of the methods of the RegistrationHandler interface.
Methods |
Description |
Signature |
Parameters |
Usage |
createUser (portalId, userData) |
It returns a user object using the supplied portal ID and user data from the third party, such as the username and email address. The User object represents an existing user record in the database or can represent a new user who hasn't been added to the database, according to the third party's user information. |
public User createUser(ID portalId, Auth.UserData userData) |
portalId Type: ID userData Type: Auth.UserData |
If no portal is configured with this provider, the portalID value may be null or empty. |
createUser (portalId, userData) |
Using the supplied portal ID and user data from the third party, such as the username and email address, it returns a user object. The User object represents an existing user record in the database or can represent a new user who hasn't been added to the database, according to the third party's user information. |
public User createUser(ID portalId, Auth.UserData userData) |
portalId Type: ID userData Type: Auth.UserData |
If no portal is configured with this provider, the portalID value may be null or empty. |
updateUser(userId, portalId, userData) |
It transforms the information for the selected user. This function is invoked when a user logs in again after previously doing so using the authentication provider. |
public Void updateUser(ID userId, ID portalId, Auth.UserData userData) |
userId Type: ID portalId Type: ID userData Type: Auth.UserData |
If no portal is configured with this provider, the portalID value may be null or empty. |
Property | Туре | Description | Required or Optional | Available Version |
Audience with the Permission criterion type | ||||
ProfileId | String | Profile ID of a user. | Required if creating or updating an audience with the Profile criterion type | 48.0 |
Subdivision | String | Subdivision of a user. | Required if creating or updating an audience with the GeoLocation criterion type and using the city property | 48.0 |
Ans: For Auth.RegistrationHandler, user data is kept in the Auth—UserData class. The third-party authentication service provider may return a substantial amount of user information, such as username, email address, location, etc. The Auth.UserData class transforms frequently used data into a standard format before sending it to the registration handler.
The syntax of the Auth.UserData constructor is as follows:

Audience with the Permission criterion type | ||||
ProfileId | String | Profile ID of a user. | Required if creating or updating an audience with the Profile criterion type | 48.0 |
Subdivision | String | Subdivision of a user. | Required if creating or updating an audience with the GeoLocation criterion type and using the city property | 48.0 |
Auth.UserData(String identifier, String firstName, String lastName, String fullName, String email, String link, String userName, String locale, String provider, String siteLoginUrl, MapattributeMap)

All authentication providers except Janrain, after a user has been authenticated using a provider, allow for the acquisition of the access token associated with that authentication provider for that user using the Auth—AuthToken Apex class. There are two ways to retrieve access tokens using Auth.AuthToken.
Register for an online Salesforce certification course for more information on authentication providers. Utilizing the Janrain accessCredentials dictionary values is required when using Janrain as an authentication provider to obtain the access token or its equivalent. Only some Janrain-supported providers offer an access token; other providers utilize different fields.
The Auth.UserData class's attributeMap variable contains the Janrain accessCredentials fields.
Property | Туре | Description | Required or Optional | Available Version |
Audience with the Permission criterion type | ||||
ProfileId | String | Profile ID of a user. | Required if creating or updating an audience with the Profile criterion type | 48.0 |
Subdivision | String | Subdivision of a user. | Required if creating or updating an audience with the GeoLocation criterion type and using the city property | 48.0 |
For additional details about accessCredentials, refer to the Janrain auth_info documentation.

Ans: The Auth.RegistrationHandler interface, which creates and updates a standard user based on information supplied by the authentication provider, is implemented in this example. For the sake of simplicity, error checking has been skipped.

Ans: This example demonstrates how to utilize a custom exception to display an error message in the URL of the page while implementing the Auth.RegistrationHandler interface. The error code and description are included in the URL and are displayed on the page if a custom exception is not used.
Some code was left out to keep this example within the custom exception.
global class RegHandler implements Auth.RegistrationHandler { class RegHandlerException extends Exception {} global User createUser(ld portalld, Auth.UserData data){ List profiles = [SELECT Id, Name, UserType FROM Profile WHERE Name = 'Power User']; Profile profile = profiles.isEmpty() ? null: profiles[0]; if(profile==null) throw new RegHandlerException('Cannot find the profile. For help, contact your administrator."); } global void updateUser(ld userid, Id portalld, Auth. UserData data){ User u = new User(id=userId); u.lastName = data.lastName; u.firstName = data.firstName; update(u); }
Ans: UserData class saves user information for Auth.RegistrationHandler. Below are some of the constructors of the UserData class.
Constructors |
Description |
Signature |
Parameters |
UserData(identifier, firstName, lastName, fullName, email, link, userName, locale, provider, siteLoginUrl, attributeMap) |
It creates a new instance of the Auth.UserData class using the specified arguments. |
public UserData(String identifier, String firstName, String lastName, String fullName, String email, String link, String userName, String locale, String provider, String siteLoginUrl, Map |
identifier Type: String firstName Type: String lastName Type: String fullName Type: String Type: String link Type: String userName Type: String locale Type: String provider Type: String siteLoginUrl Type: String attributeMap Type: Map |
