OSM Worldwide is one of the largest last-mile delivery partners for USPS. Last-mile delivery is the final leg of a package's trip, from a regional hub to the customer's door. ShipHero connects directly to OSM's own shipping APIs, with no third-party service in between. Connect an OSM account in ShipHero to generate shipping labels, pull live rates, and manage packages through the platform you already use.
Important
OSM support in ShipHero currently covers domestic US shipments only, including US territories. The OSM Rating API only returns rates for domestic packages. The OSM Label API can technically create international labels, but ShipHero doesn't create labels with a zero shipping cost, so international labels aren't available yet.

OSM Features Not Supported in ShipHero
| Feature | Status | Notes |
|---|---|---|
| International Labels | Not Supported | The OSM Label API can technically create international labels, but ShipHero doesn't create labels with a zero shipping cost, and the OSM Rating API doesn't return international rates. |
| Manifesting (End-of-Day) | Not Supported | End-of-day manifesting isn't available through the OSM integration. |

| Tracking | Not Supported | Planned for a future release through the OSM Package Tracking API v2.1. |
| Void Label | Not Supported | OSM has no void API endpoint, so ShipHero can't notify OSM when you void a label. You can still void an OSM label from ShipHero's shipping screen. OSM only bills for a label once a carrier scans it, so a voided or unused label is never charged. |
