Carriers / Mainfreight

Handle Mainfreight shipments through one Unified API

If Mainfreight 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.

Carrier-specific handling

What ShipPeek handles for Mainfreight

ShipPeek is not asking your team to buy a standalone Mainfreight API. Mainfreight 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 MFGN and your enabled carrier-account configuration from one place instead of hardcoding Mainfreight rules into every product workflow.

Workflow mapping

ShipPeek maps Mainfreight 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 Mainfreight in ShipPeek

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

Tracking

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

Rates

Request eligible Mainfreight rates without creating a carrier-specific quoting path.

Booking

Create supported Mainfreight shipments from the same integration surface when your account is enabled.

Documents

Pull BOLs, delivery receipts, and other shipment documents into normalized workflows.

Integration model

One API contract, Mainfreight-aware routing

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

Track Mainfreight shipments and status events without portal checks
Request eligible Mainfreight rates through the Unified API
Create Mainfreight bookings where your carrier account allows it
Pull Mainfreight BOLs and delivery documents into your system
Keep Mainfreight inside the same API contract as the rest of your carriers

Unified API example

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

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

How it works

How a Mainfreight request moves through ShipPeek

Send one request

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

Apply carrier setup

ShipPeek uses the enabled Mainfreight configuration, including carrier identifier mfgn, 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 Mainfreight

How does ShipPeek support Mainfreight?

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

Can I track Mainfreight shipments?

Yes. ShipPeek normalizes Mainfreight 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 Mainfreight 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 Mainfreight bookings?

Yes, where enabled through ShipPeek's Unified API. Booking still depends on your carrier account, service, permissions, and Mainfreight rules.

Can I get Mainfreight labels or documents?

ShipPeek can return Mainfreight BOLs, delivery receipts, or carrier documents where available through enabled Unified API workflows.

What does ShipPeek handle for Mainfreight?

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 Mainfreight and your carrier account setup.

Is ShipPeek an official Mainfreight API?

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