How to validate user properties with regular expressions

When a user registers or updates their account, your application uses the user registration API. It is common for the user interface to enforce the data entry rules and validate the values entered by the user. However, an alternative approach is to perform data validation on the server.

Backendless Console includes several pre-configured regular expressions (regex) for the most common data types, such as email address, URL, social security number, and US phone number. Additionally, you can specify your own regex. To configure a validator for a user property:
