Converge supports deduplication natively. You can deduplicate events with an optional eventID parameter. This is especially important for events that are used as conversions. Converge will deduplicate events with the same eventID at ingestion time. The eventID will also be forwarded to your destinations for in-platform deduplication.

Limitations of deduplication

Converge only supports deduplication within a single datasource, for now. If you track the same event across multiple datasources, these will not be deduplicated.
