🎉 ShipEngine is becoming ShipStation API 🎉

Over the next few months you'll notice the ShipEngine website, documentation portal, and dashboard being rebranded as ShipStation API. For our ShipEngine customers, you don't need to take any action or change any of your integrations in any way. All endpoints will remain the same and continue to function as they always have.

To learn more about what's coming, review our New ShipStation API page.

Get Credential Requirements

This endpoint is used to retrieve a description of the format you must use when sending your credentials to connect a particular LTL carrier. Since each carrier will have different credential requirements, use this endpoint to ensure you know what is required to connect successfully.

SCAC & Carrier Codes

Each LTL carrier has one or more SCACs (Standard Carrier Alpha Code) used to uniquely identify that carrier. The SCAC for a carrier is referred to as carrier_id. To get the credential requirements for a particular carrier, you need to pass its SCAC as the carrier_code.
