Deduplication

Identifying records or events that represent the same thing and deciding how to prevent them from being created or processed more than once.

Source content checked . English translation published 2026-10-27.

In business automation

Deduplication starts with defining identity. An email address, customer ID, and event ID represent different things; two inquiries from the same person are not necessarily the same inquiry.

Examples

These examples illustrate a possible workflow. Adapt the connections and rules to your own systems.

Business process example

The same form arrives twice with an identical submission ID. One inquiry is retained, but a new inquiry from the same customer about a different subject is opened as a new activity on the existing record.

Relevant tools

Managing contacts and CRM integrations requires consistent identification and update rules throughout the process.

What to check

  • Do not merge records based on name alone. Define what counts as a duplicate and what information to retain when records are not exactly identical.
