Hi @seljo-ch, n8n doesn’t really have a built-in de-duplication logic for webhooks. However, if you’re okay with adding additional middleware you could consider this approach. Essentially have one workflow just accepting all webhooks (including the duplicates), then sending a message to a message broker. You can then avail of the Parallel Message Processing Limit option to process only dataset at a time and will be able to perform your custom de-duplication check.
