Genesys Cloud Resource Center provides administrators with comprehensive data filtering capabilities to protect sensitive information in digital communications through masking or blocking data patterns. Users must possess specific Data Privacy > Masking Rule permissions (Add, Delete, Edit, Execute, View) to create and manage filters. The filter creation process requires entering a unique name, optional description, selecting message channel direction (inbound to hide data or outbound to block data), choosing applicable digital channels, and defining a regular expression pattern to identify and mask sensitive data with X characters. For example, the pattern `d{1,3}.d{1,3}.d{1,3}` partially masks IPv4 addresses by replacing matched digits. An optional test preview function validates filter behavior before activation to ensure proper functionality. Filters automatically activate upon creation with a maximum limit of 15 active filters per channel; additional filters require disabling existing ones. Common use cases include protecting email addresses, government identification numbers, and financial account numbers in digital interactions. The system implements a channel-specific filter limit that prevents creation of additional filters once the threshold is reached; users must disable an existing filter to add new ones, ensuring controlled management of data protection rules. The documentation provides multiple support mechanisms for users, including feedback options to report article accuracy and helpfulness with role specification (Agent, Administrator, Developer/Engineer, Partner, Supervisor, and Support). Related resources encompass guidance on account settings, data filter management, regular expression syntax, digital data filtering rules, webhook event filtering through triggers, context filtering in Genesys Agent Copilot, and saving view filter and column configurations. Users unable to find answers in documentation can access community support for additional assistance.
