Create a validation rule

Creates a data validation rule for specified attributes in your schema. User data can be validated or transformed by the new rule any time the underlying user profile attribute is updated.

Example uses for this operation include:

• Defining a validation rule for rejecting strings that don't match a regular expression (for example, rejecting username values that don't use the English alphabet).
• Limiting input to a certain length (i.e., a specific number of characters).

Refer to the Registration error codes page for details on error codes.
