Carrier guide

Carrier-specific details, supported features, and configuration notes.

ShipPeek connects to carriers via their native APIs. Each carrier has different capabilities for rating, booking, tracking, and document generation.

Filtering carriers in rate requests

Pass the carriers query parameter to limit which carriers return rates:

curl -X POST "https://api.shippeek.com/rates?carriers=exla,saia,odfl" \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{ ... }'

Only the specified carriers are queried. Omit the parameter to get rates from all configured carriers.

LTL carrier notes

Facility type charges

Location-based accessorials (residential delivery, trade show, limited access, etc.) are automatically applied based on the originType and destType fields in your rate request. You do not need to list these in the charges array.

Accessorials

LTL accessorials are passed in the charges array. See the Accessorials reference for the full list.

arrival notice and arrival schedule are mutually exclusive. Include one or the other, not both.

Hazardous materials

If any item has hazardous: true, you must provide emergencyName and emergencyPhone in the booking request. Not all carriers support hazmat shipments — unsupported carriers return an error status in the rate response.
