function custom_user_validation( $user_data ) {
// Perform custom validation or modification of user data
if ( empty( $user_data[‘user_email’] ) ) {
// Reject user insertion if email is empty
return new WP_Error( ‘invalid_email’, __( ‘Email is required’ ) );
}
// Allow user insertion to continue
return $user_data;
}
add_filter( ‘rest_pre_insert_user’, ‘custom_user_validation’ );
