Purpose

1. Automates the identification, correction, and elimination of inaccurate, incomplete, or duplicate data across event technology platforms.

2. Facilitates real-time, high-volume data cleansing and deduplication in registration, ticketing, CRM, and engagement systems, improving user experience, analytics accuracy, communications, and compliance.

3. Ensures automatable standardization of data formats, validation of contact details, and consolidation of attendee records by event-specific and cross-platform integrations.

Trigger Conditions

1. Automatedly triggers when new records are added via APIs, web forms, uploads, or integrations.

2. Initiates on scheduled intervals — hourly, daily, or pre/post-event.

3. Activated by user-defined thresholds (e.g., % of duplicate records).

4. Triggered by external system notifications, webhook events, or data sync failures detected via monitoring automators.
