# Deduplication

Published 27 August 2025 · Event Gateway

Ignore redundant events with configurable matching strategies

Deduplication removes redundant events by comparing them against previously processed events within a time window. Reduce processing costs from payment request redelivery, noisy updates (ie: Shopify product updates), and multi-app webhook installations.

Here's what you can do:

* Exact Deduplication: Drop perfectly identical webhooks for retry storms
* Field-Based Matching: Choose which fields define duplicates — use request IDs or exclude volatile fields like timestamps
* Flexible Time Windows: Configure 1 second to 1 hour windows to balance suppression with legitimate updates

Deduplication works as a connection rule alongside filters and transformations. Try it out to reduce processing costs and eliminate webhook noise.
