Updates the deduplication rules for property messages that are reported by the devices of a product. If the call succeeds, the new rules are immediately applied to all the devices of the product.

Message deduplication rules

Based on the rules that you set, IoT Platform determines whether to use the rules engine or server-side subscriptions to forward property data that is reported by devices to a specified destination.

The triggering conditions of rules are related by the logic AND relation. For example, if you set the PropertyValueFilter=true and PropertyTimestampFilter=true conditions, the rule to remove duplicate messages is triggered only when both of the conditions are met.
