Does the public GraphQL API expose delivery timestamp or tracking event history for outbound ShippingLabel records? We can see tracking_status, delivered, picked_up, tracking_url, and parcelview_url, but we need delivered_at / delivery timestamp for transit-time reporting.
At the moment, the public GraphQL ShippingLabel object exposes the tracking summary fields you mentioned, such as tracking_status, delivered, picked_up, tracking_url, and parcelview_url, but it does not currently expose a direct delivery timestamp like delivered_at, nor the full carrier tracking event history.
We could expose last_tracking_update which will be delivery date time if delivered is true.
Would that work? also please check your profile, there is a field to add your account id in ShipHero. That would allow more accurate responses.
