EDI and API in Shipping: What’s the Difference, and When to Use What?
The shipping industry has come a long way from paper-based documentation and fax machines to digitalized processes and technological advances. Today, businesses demand speed, automation, and real-time data exchange. And that’s where EDI and API step in. Both technologies allow digital communication between several different systems, making booking, tracking, invoicing, and documentation (to only name a few) faster and more reliable. But while they serve a similar purpose, EDI and API differ in how they work, how they integrate, and what kind of value they deliver. Let’s take a look at the differences and the respective use cases between the two of them.

What is EDI?
EDI, which is short for Electronic Data Interchange, is a structured, computer-to-computer method for exchanging business documents in standardized formats. It’s been around for decades and remains widely used in logistics and international shipping.
In a typical EDI setup, information such as bookings, shipping instructions, or container status updates is exchanged automatically between a carrier and a customer’s system. It’s highly efficient once configured but often a bit more rigid in terms of structure and setup.
TLDR: EDI lets two systems “talk” to each other using pre-agreed message formats, without any manual input.
ERP stands for “Enterprise Resource Planning” and stores most information about transactions, finances, and orders of a company. A TMS is a “Transport Management System” and mainly used in the logistics sector to, well, manage the movement of goods.
What is an API?
API, or Application Programming Interface, is a more recent, flexible way for software systems to interact. APIs allow customers to request data or trigger actions in real-time. For example, with an API like our Live Position API, you can request the latest ETA for a specific container, get available sailing schedules, or place a booking directly from your in-house application. APIs are fast, easy to scale, and ideal for companies looking for on-demand access to data.
To sum it up: APIs connect your system with the carrier’s system so you can pull or push specific data instantly.
Key benefits of APIs:
- Real-time data access and updates
- Easy to integrate and customize
- Scalable and flexible across use cases
- Great for dynamic, event-driven workflows
| EDI | API | |
|---|---|---|
| Technology | Older, batch-based | Modern, real-time |
| Integration | Complex setup, usually via VANs or point-to-point | Lightweight, often REST-based |
| Speed | Scheduled transfers (e.g., every 15–30 min) | Instant access and responses |
| Flexibility | Rigid data formats (EDIFACT, ANSI X12) | Flexible, often JSON/XML |
| Use case | High-volume, stable data exchange | On-demand, interactive workflows |
| Maintenance | Requires significant IT involvement | Easier to update and manage |
When Should You Use EDI?
EDI remains the preferred solution for many enterprise-level shippers, especially when:
- You have a high volume of regular transactions (e.g., bookings, confirmations, invoices)
- Your systems are already EDI-capable
- You need robust, tested processes with established partners
- You operate in regions or industries where EDI is still the standard
Carriers like we as Hapag-Lloyd offer bilateral EDI setups that automate the flow of information for the entire shipping process, streamlining your supply chain efficiently.
When To Use APIs Instead
APIs are ideal when you want quick and easy access to real-time data and need a tad bit more flexibility or a fast integration into modern systems.
APIs are also more convenient when your development team prefers modern tech stacks (e.g., REST, JSON) or when you want to enhance your visibility tools, customer portals, or mobile apps.
With our API Developer Portal, you can easily browse, test, and integrate APIs for tasks like:
- Tracking containers in real time
- Getting sailing schedules or ETA updates
- Managing shipments wth reefer containers
- Accessing PTI information
Can You Use Both?
Absolutely – a mix of both EDI and API is actually a very common practice. Many companies today use a hybrid model, combining EDI for high-volume, structured transactions and APIs for dynamic, real-time data access.
For example: EDI is used to submit large-scale bookings, invoicing and customs documentations whereas API is used to track individual containers or get live status updates or for visibility dashboards.
This approach allows you to modernize at your own pace without abandoning tried-and-tested processes.
Final Thoughts
Digital integration isn’t just about efficiency. It’s about visibility, speed, and better customer service. Whether you choose EDI, API, or a mix of both, you’re building a more connected and responsive supply chain.
