EDI & API Integration for Shippers: A Freight Broker's Guide
What EDI 204/990/214/210 and API integration actually do, and how connecting your TMS directly to a broker automates load tendering from quote to invoice.
If your team is still emailing rate confirmations back and forth or re-typing load details into two different systems, EDI and API integration exist to remove that step entirely. Here's what each one actually does, and how to know which fits your operation.
What EDI Actually Is
EDI (Electronic Data Interchange) is a standardized message format that lets two completely different computer systems exchange logistics data automatically. It's been the backbone of freight technology for decades because it's rigid, predictable, and extremely reliable at high volume — exactly what you want when hundreds of loads are moving through your system every week.
The Four EDI Transaction Sets That Matter
204 — Load Tender: Your TMS sends IZY the load details automatically the moment a shipment is ready to move — origin, destination, equipment type, weight, and appointment windows — with no manual entry.
990 — Tender Response: IZY's system responds automatically confirming acceptance (or decline) of the tendered load, so your team knows within moments whether it's covered.
214 — Shipment Status: Automated status pings as the load moves — dispatched, in transit, at delivery — pushed directly into your TMS without anyone checking a portal.
210 — Invoice: Once delivered, the invoice transmits electronically, matching automatically against the original tender to catch discrepancies before they become disputes.
Where API Integration Fits In
API integration works differently: instead of fixed message formats sent in batches, APIs allow two systems to ask each other questions and get answers in real time. That makes APIs a better fit for things like on-demand rate quotes, instant tracking pings, or triggering a single action (like requesting a quote) without waiting for a scheduled batch transmission.
Most high-volume shippers end up using both: EDI for the core tender-to-invoice workflow, and APIs layered on top for real-time visibility and ad-hoc requests.
Do You Actually Need This?
If you're tendering a handful of loads a week, manual entry through a broker's TMS or chat assistant is often just as fast and requires zero IT involvement. EDI and API integration start paying off once you're moving enough volume that manual entry becomes the bottleneck — typically shippers tendering dozens of loads weekly, or those who need tender-to-invoice data flowing into their own systems for reporting.
Setting Up Integration With IZY Logistics
IZY Logistics supports direct TMS-to-TMS EDI and API connectivity for shippers who want automated load tendering. Setup typically takes one to two weeks depending on your TMS vendor and how much field mapping is required. If you don't have EDI capability, that's fine too — our own TMS and chat assistant handle manual quoting and tendering just as reliably.
IZY Logistics is a licensed freight broker (MC #1615290) supporting EDI and API integration for shippers who need automated tendering. Let's talk about your setup.

What is EDI in freight and logistics?
EDI (Electronic Data Interchange) is a standardized format that lets a shipper's TMS and a freight broker's system exchange load information automatically — tenders, status updates, and invoices — without anyone re-typing data by hand.
What do EDI 204, 990, 214, and 210 mean?
These are the core EDI transaction sets used in freight: 204 is a load tender, 990 is the carrier's accept or decline response, 214 is a shipment status update, and 210 is the freight invoice. Together they cover a load from tender to payment.
What is the difference between EDI and API integration?
EDI uses fixed, older message formats that are extremely reliable for high-volume, standardized data. API integration is more flexible and modern, allowing real-time two-way communication between systems. Many shippers use EDI for core tendering and APIs for tracking or ad-hoc requests.
Does my TMS need to support EDI to work with IZY Logistics?
No. IZY Logistics supports direct TMS-to-TMS EDI and API connections for shippers who have them, but manual load entry through our TMS or chat assistant works just as well if you don't have EDI capability.
How long does it take to set up EDI or API integration with a broker?
A straightforward EDI or API connection between compatible systems typically takes one to two weeks, including testing. Timelines vary based on your TMS vendor and how much custom mapping is required.
