Steps
Call the Deliveries endpoint for an order to retrieve the Delivery object, which includes pickup/dropoff ETA or actual timestamps (estimates refresh roughly every 60 seconds until the actual event occurs)
Use the geofence-entry timestamps in the Delivery object to detect when a driver has arrived near pickup or dropoff, useful for kitchen-timing or customer-notification logic
GET the merchant fulfillment-time-estimate endpoint to read your current pickup and delivery prep-time estimates
PUT updated fulfillment-time estimates when kitchen throughput changes (e.g. during a rush) so Grubhub's promised delivery times stay accurate
Reconcile estimated vs. actual pickup/dropoff times over time to tune default fulfillment estimates
Known gotchas
ETA fields switch from 'estimate' to 'actual' once the corresponding event occurs — don't keep displaying a stale estimate after pickup/dropoff has actually happened
Fulfillment-time-estimate endpoints affect Grubhub's customer-facing delivery promise, so pushing an unrealistically short estimate can increase late-order penalties
Delivery tracking data lives in the Deliveries API, separate from order-status endpoints — pulling only order status will miss ETA/geofence detail
