Asana: Webhooks and event streams partial data loss
Timeline of updates
- resolved
From 2026-08-04 15:25 UTC until 2026-08-06 03:51 UTC, Asana failed to send some events to registered webhooks and to return them in the event streams API. Apps which rely on this should refetch the underlying data from the Asana API. Existing webhooks and event streams will continue to function, but events from the incident window will not be sent.
Most events with type
taskand actionchangedwere dropped during this period. Other events are not affected.The root cause of the incident was traced to a code change which unintentionally dropped change events for most fields on the task type, and the change was reverted.
Archive proof
Rewindex commits each version of an incident it captures to a daily checkpoint, chains it to the day before, and has the checkpoint timestamped by FreeTSA and DigiCert. That proves this record existed by then and has not been changed since, by anyone, Rewindex included.
