How do I manage data integrity when syncing large volumes of data between Zoho apps?


Info

When syncing large datasets, data integrity is critical. Follow these best practices:

  1. Use Unique Identifiers:
    Always sync records using a unique field like Email, Contact ID, or Custom Reference ID.

  2. Enable Field Mapping Carefully:
    Ensure that every important field is correctly mapped between apps. Missing mappings can cause incomplete or incorrect syncs.

  3. Avoid Circular Syncing:
    Set clear directions—one-way or two-way—so data doesn’t keep overwriting itself from both ends.

  4. Monitor Logs & Set Notifications:
    Review sync logs regularly for failures or duplicates. Use alerts to notify admins if sync fails.

  5. Perform Sync in Batches:
    For large records, perform batch imports or chunk-based syncing (Zoho Flow and APIs support this).

Example: While syncing 10,000 CRM contacts with Campaigns, a mismatch in email field caused duplicates. Using “email = unique identifier” resolved the issue and ensured consistency.

This ensures clean, trustworthy data across departments and apps.
