Our events team manages attendee data across multiple platforms - SAP CX for event registration, external webinar platforms, and third-party event apps. We’re struggling with data governance challenges around cross-platform data consolidation, especially duplicate attendee records and inconsistent consent tracking. When someone registers through SAP CX but then uses a different email for the webinar platform, we end up with duplicate profiles. We’re also finding it difficult to track consent preferences consistently across platforms - someone might opt out of marketing emails in one system but still receive them from another. What are the best practices for maintaining clean attendee data and proper consent tracking when you’re working with multiple event platforms?
The hub-and-spoke model makes sense. How do you handle the timing of syncs though? If someone attends a webinar and then immediately registers for another event, do you wait for the batch sync or is there real-time integration? I’m concerned about the lag between platforms causing duplicate registrations.
Let me synthesize the best practices for data governance across event platforms based on what’s been discussed and my experience with similar implementations:
Cross-Platform Data Consolidation: Establish SAP CX as your system of record for attendee master data. Implement a hub-and-spoke integration architecture where all external event platforms (webinar tools, mobile event apps, registration sites) sync data back to SAP CX rather than trying to maintain consistency across multiple systems. Use a combination of matching strategies for deduplication - deterministic matching on email and phone number for high-confidence matches, and fuzzy matching on name plus company for uncertain cases. Create a golden record concept in SAP CX that serves as the unified attendee profile, linking all platform-specific records while maintaining the original data in source systems for audit purposes.
Deduplication and Cleansing: Implement proactive duplicate prevention at the point of registration. When attendees register through SAP CX, use real-time duplicate detection to prompt them if a similar profile exists, encouraging them to use the same email address across platforms. For external platform registrations, trigger real-time API calls to SAP CX during registration to check for existing profiles and either link to existing records or create new ones with appropriate flags. Run automated weekly deduplication processes using confidence-scored matching algorithms, but route uncertain matches (60-85% confidence) to event operations staff for manual review. Track duplicate patterns to improve matching rules over time - if staff consistently merge certain types of records, adjust your automated matching criteria.
Consent Tracking: This is your highest-priority governance challenge for regulatory compliance. Implement a centralized consent management service that acts as the single source of truth for all marketing and communication preferences. Configure all systems - SAP CX, webinar platforms, email marketing tools - to check consent status through this service before any communication. Use event-driven sync for consent updates so changes propagate across platforms within minutes, not hours or days. Maintain a complete audit trail of consent changes including timestamp, source system, and user action. Structure consent at a granular level (email marketing, event notifications, third-party sharing) rather than a single opt-in/opt-out flag, and ensure this granularity is respected across all platforms. For GDPR compliance, implement right-to-be-forgotten workflows that cascade delete requests across all integrated systems.
Integration Timing Strategy: Use hybrid sync patterns based on data sensitivity and business requirements. Real-time event-driven integration for registration events, consent changes, and profile updates ensures immediate consistency for time-sensitive data. Batch processes for bulk data like attendance records, session feedback, and historical reconciliation run on scheduled intervals (typically nightly). Implement conflict resolution rules for cases where the same data changes in multiple systems between syncs - most recent timestamp wins for consent preferences, but SAP CX master data takes precedence for core profile fields.
The goal is creating a governed data ecosystem where attendees have a consistent experience across platforms, marketing teams can trust their data for targeting and personalization, and compliance teams have confidence that consent preferences are properly managed across all touchpoints.
We implemented a registration flow that encourages attendees to use the same email across platforms. During SAP CX event registration, we display their existing profile email and ask them to confirm they’ll use the same for webinar platforms. This simple UX change reduced our duplicate rate by about 40%. For the remaining duplicates, we have a weekly deduplication and cleansing process that our event ops team reviews.
