Electronic Logging Devices (ELDs) are mandated for most commercial motor vehicles, and they generate a wealth of data about your fleet—GPS location, driving hours, engine diagnostics, vehicle performance, and more. But that data only creates value if it's accessible where you need it.
Integrating your ELD with your Transportation Management System (TMS) connects fleet data directly into your dispatch and operations workflow—eliminating manual data entry, improving tracking accuracy, and enabling compliance monitoring without extra effort.
This guide explains how ELD integrations work, what data flows between systems, and what to look for when evaluating ELD-TMS connectivity.
What is an ELD Integration?
An ELD integration is a data connection between your ELD provider's platform and your TMS, established via API (Application Programming Interface). Once connected, your TMS can pull data from the ELD automatically—without any manual export, import, or re-entry.
Most modern ELD providers offer open APIs that allow TMS platforms to access:
- Real-time GPS location
- Hours of Service (HOS) status
- Vehicle diagnostics
- Driver identification
- DVIR (Driver Vehicle Inspection Reports)
- Mileage data
What Data Flows From ELD to TMS?
GPS Location Data
This is the most commonly used ELD integration data point. Your TMS pulls current truck location every 5-15 minutes and uses it to:
- Display live truck positions on a dispatch map
