User Registration

The user registration API creates a user account in your application. A registration request must provide a user object as a collection of key/value properties. The collection must contain a property marked as identity as well as the "password" property. The default identity property is "email", however, it can be changed in Backendless Console. Additionally, the "email" property is required if your Backendless application is configured to confirm email addresses for the registered users.

When this API is used to convert a guest user account to a regular registered user,the request body must include the objectId property. The value of the property is the same as the one returned from the Guest Login API.

Turning Registration Off

User registration can be disabled using the Backendless Console:

1. Login to the console and select the application.
2. Click the Users icon in the vertical icon menu on the left.
3. Click User Registration.

The Registration toggle turns the registration API on or off. When the registration is turned off and a user attempts to register, the system returns error 3009.

Email Confirmations

Backendless can send out an email requesting new registered users to confirm their email address. This feature can be configured in the Backendless Console:

1. Log into the console and select the application.
2. Click the Users icon in the vertical icon menu on the left.
3. Click User Registration.

When email confirmations are enabled (the feature is disabled by default), the "email" user property is required and must contain a value formatted as an email address. When user registers or when you create a user account in the Users database table,  Backendless sends an email to the user with a link they need to click to confirm their email address. To change the text of the email message,  click the Messaging icon in the vertical icon bar in Backendless console and select the EMAILS tab. Use the Confirmation template template.

To resend the confirmation email, use the Resend Email Confirmation API.

When email confirmations are enabled in the app, new registered users will not be able to login until they confirm their email address. For more information see the User Status section of this guide.

Confirmation Link Workflow

When user clicks the confirmation link in the email, Backendless performs various checks and displays a web page informing the user about the status. The web pages can be edited in the Backendless UI Builder. They are available in the FRONTEND section of Backendless Console - make sure to select the system UI Container:

The following pages are available depending on the status of the link and the user account:

Link/User Status	Page to display
Link expired	Page name: confirmation-expired
User is disabled. This may happen if you modified the user's status to DISABLED. This can be done manually in Backendless Console or with the user status management API.	Page name: confirmation-disabled
User's email has been confirmed.	Pagge name: confirmation-confirmed

If you make any changes to the confirmation pages, make sure to re-publish the system UI Container by clicking the Publish UI Container icon:

It is important that the UI Container is published to the system directory located under the web directory:
