This is usually related to synchronization rules, field mappings, or lead qualification criteria rather than a general issue with the integration itself.
A few things worth checking in the Cvent Salesforce integration settings:
Verify that the Lead object is selected and enabled for synchronization.
Review any filters or sync rules that might exclude certain attendees (for example, registration status, event type, or attendee activity requirements).
Check whether required Salesforce fields are missing, as records can fail to create if mandatory values are not populated.
Review the Attendee Activity Sync settings to confirm that the relevant attendee statuses and activities are included.
Look at the integration logs or error reports in the Cvent Salesforce app to identify whether specific leads are failing due to validation rules, duplicate rules, or field mapping issues.
We've seen similar situations where Salesforce validation rules, duplicate management settings, or incomplete field mappings prevented some records from syncing successfully.
