Delivery records cover direct sends, automations, campaigns, and one-device
tests. Filter by push app, platform, environment, or status. A detail response
includes the provider message ID and chronological provider/client events,
including the reporting device and provider name.Use this trace together with push device diagnostics. A provider send event can
still be followed by a stale-token failure, OS suppression, foreground-handler
behavior, or missing client instrumentation.
