Carriers / US Special Delivery

Handle US Special Delivery shipments through one Unified API

If US Special Delivery is part of your shipping mix, ShipPeek gives your team one place to request enabled rates, bookings, tracking, labels, and documents. You keep ShipPeek's Unified API; ShipPeek handles the carrier-specific codes, credentials, mappings, and response differences.

What ShipPeek handles for US Special Delivery

ShipPeek is not asking your team to buy a standalone US Special Delivery API. US Special Delivery runs as an enabled carrier workflow inside ShipPeek's Unified API, with carrier-specific setup, mapping, and response handling kept behind one contract.

Carrier setup

Use UPSD and your enabled carrier-account configuration from one place instead of hardcoding US Special Delivery rules into every product workflow.

Workflow mapping

ShipPeek maps US Special Delivery rates, tracking events, bookings, labels, and documents into normalized objects where those workflows are enabled.

Operational accountability

Carrier responses and exceptions come back through the Unified API so your team can tell whether an issue is credentials, lane/service eligibility, missing documents, or carrier-side availability.

Carrier workflows

What you can do with US Special Delivery in ShipPeek

Capabilities are enabled per account and carrier configuration, so this page shows the US Special Delivery workflows ShipPeek can route through the Unified API — not a promise that every lane or service is available for every account.

Tracking

US Special Delivery tracking events come back in the same shipment status model you use across every supported carrier.

Rates

Request eligible US Special Delivery rates without creating a carrier-specific quoting path.

Integration model

One API contract, US Special Delivery-aware routing

Keep ShipPeek's Unified API as the integration surface. Use carrier identifier upsd to route eligible workflows to US Special Delivery; ShipPeek keeps carrier-specific request fields, credentials, and response mappings out of your product code.

Track US Special Delivery shipments and status events without portal checks
Request eligible US Special Delivery rates through the Unified API
Keep US Special Delivery inside the same API contract as the rest of your carriers

Unified API example

curl "https://api.shippeek.com/track/123456789?carrier=upsd" \
  -H "Authorization: Bearer YOUR_TOKEN"

The carrier identifier selects an enabled workflow. It does not create a separate US Special Delivery product surface; ShipPeek's Unified API remains the contract.

How it works

How a US Special Delivery request moves through ShipPeek

Send one request

Your app sends a standard ShipPeek request for the workflow it needs and includes US Special Delivery only when that carrier should handle the shipment.

Apply carrier setup

ShipPeek uses the enabled US Special Delivery configuration, including carrier identifier upsd, credentials, and available workflow rules.

Translate the response

Carrier rates, tracking events, labels, or documents are mapped back into ShipPeek's normalized fields where available.

Act on one model

Your team gets a consistent response shape with enough carrier context to route support, exceptions, and downstream automation.

FAQ

Questions about US Special Delivery

How does ShipPeek support US Special Delivery?

ShipPeek supports US Special Delivery as a carrier workflow inside the ShipPeek Unified API. It is not a separate US Special Delivery-only product or an official US Special Delivery-owned API; enabled capabilities depend on your account, region, credentials, and carrier permissions.

Can I track US Special Delivery shipments?

Yes. ShipPeek normalizes US Special Delivery tracking events into the same shipment status model used across supported carriers, so operations and support teams are not forced back into a carrier portal for every update.

Can ShipPeek get US Special Delivery rates?

Yes, where your carrier account, lane, service, and credentials are enabled. The request still uses ShipPeek's Unified API; ShipPeek handles the carrier-specific mapping.

Can ShipPeek create US Special Delivery bookings?

Booking is not currently listed for this carrier profile. Contact ShipPeek to review whether this workflow can be enabled through the Unified API.

Can I get US Special Delivery labels or documents?

Labels and documents are not currently listed for this carrier profile. Capabilities vary by account and carrier configuration.

What does ShipPeek handle for US Special Delivery?

For enabled workflows, ShipPeek handles the Unified API contract, carrier identifier, request and response mapping, status normalization, and document workflow shape. Carrier acceptance, service availability, rates, and document availability still depend on US Special Delivery and your carrier account setup.

Is ShipPeek an official US Special Delivery API?

No. ShipPeek is a unified logistics API platform that connects to supported carrier integrations. ShipPeek is not US Special Delivery or a US Special Delivery-owned API.
