Summary

EDI is still the foundation of global B2B communication. Even as APIs and cloud integrations grow, industries rely on EDI because it is:

• Proven

• Standardized

• Secure

• Scalable

• Accepted worldwide

From retail to healthcare, EDI remains essential for keeping supply chains running smoothly.

How APIs Are used Instead of EDI Nowadays

Today, many businesses — especially e-commerce, logistics, retail, and fintech — use APIs to support or replace EDI where speed and flexibility are needed.

Below is a detailed overview of how APIs are transforming B2B integration.

1. Real-Time Data Exchange (vs. EDI Batch Processing)

Traditional EDI sends files in batches:

• Orders every 15 mins or every hour

• Ship notices once the warehouse completes picking

• Inventory updates daily or hourly

APIs allow real-time data exchange:

• Inventory can be updated instantly

• Order confirmation is instant

• Tracking updates are immediate

• Payment confirmations happen instantly

Example:
Amazon, Shopify, eBay APIs instantly send order details to sellers (no EDI 850 needed).

---

2. APIs Are Used for Modern Platforms (EDI Can’t Integrate Easily)

Platforms like:

• Shopify

• WooCommerce

• Amazon Seller Central

• BigCommerce

• Stripe

• Razorpay

• UPS/FedEx

• Google Cloud / AWS

These platforms do not support EDI directly.

They use REST APIs or Webhooks, not EDI.

Example
A seller receives an order from Shopify via API, not via EDI 850.

---

3. APIs Enable Event-Based Systems (Webhooks)

APIs support events, something EDI cannot do.

Example events:

• Order created

• Item shipped

• Label generated

• Payment completed

Webhook → API Callback
The system instantly notifies another system when something happens.

EDI has no capability for event-driven communication.

---

4. APIs Reduce Transaction Cost & Complexity

EDI requires:

• Standard mapping

• Middleware

• AS2/SFTP connections

• Message translators

• EDI analysts

APIs only need:

• URL + Token

• JSON/XML data

• Simple authentication (OAuth2/Bearer Token)

Example
Instead of sending an EDI 856 ASN via AS2, the warehouse updates the retailer via a POST /shipments API with JSON.

---

5. APIs Use Modern Security (OAuth2, JWT, TLS 1.3)

EDI uses older security protocols:

• AS2 certificates

• SFTP keys

• MDN acknowledgments

APIs use:

• OAuth2

• JWT tokens

• API gateways

• Rate-limiting

• Zero-trust policies

Modern and faster.

---

6. APIs Integrate Better With Mobile, Cloud & SaaS

EDI translator cannot easily run inside:

• Mobile apps

• Serverless platforms

• Microservices

• Cloud-native systems

APIs are built for:

• AWS Lambda

• Azure Logic Apps

• Google Firebase

• Mobile apps (Android/iOS)

• Cloud-based ERPs

---

7. APIs Are Used for Shipment Tracking Instead of EDI 214

Earlier:
EDI 214 Shipment Status was used by trucking carriers.

Now:
Logistics companies like UPS, DHL, FedEx, Delhivery, BlueDart provide tracking APIs.

Warehouse / ERP systems call:

GET /tracking/{tracking_number}

Instead of waiting for EDI 214.

---

8. APIs Are Used for Invoicing Instead of EDI 810

Fintech platforms use API-based invoicing:

• Zoho

• QuickBooks

• Stripe

• Razorpay

• SAP Cloud

• Tally API

EDI 810 becomes optional.

---

9. E-Commerce Uses APIs Instead of EDI

For marketplaces:

• Amazon

• Flipkart

• Etsy

• Myntra

• Ajio

• Meesho

APIs drive the entire order flow, not EDI.

EDI is used mostly in:

• Retail (Walmart, Target, Kroger)

• Manufacturing (Automotive, Aerospace)

• Healthcare (Hospitals, Pharma)

• Logistics (Carriers)

---

10. Hybrid Model: API + EDI Together

Most companies use a hybrid model:

Scenario	Technology
Large retailers (Walmart, Costco):	EDI
E-commerce platforms:	APIs
Logistics status updates:	APIs
Invoices / ASN for enterprise customers:	EDI
Small suppliers:	Web-EDI / REST API
Internal system sync:	APIs

Many EDI tools now support API + EDI together:

• Cleo Integration Cloud

• MuleSoft

• Boomi

• SAP CPI

• OpenText

EDI Using APIs — The Modern Approach

Traditional EDI uses file-based communication (via VANs, AS2, SFTP, etc.), while API-based EDI uses web services to send/receive data instantly between systems like SAP, Oracle, or Amazon Vendor Central.

---

1. REST API in EDI

REST APIs are the modern choice for cloud-based EDI platforms (like Cleo, SPS Commerce, or TrueCommerce).

Example: Sending an EDI 856 (ASN) through REST API

Scenario:
Supplier ships goods to Amazon and sends the ASN using an EDI REST API.

Request:

POST https://api.edi-platform.com/asn
Content-Type: application/json
Authorization: Bearer <AccessToken>

Payload (JSON):

{
  "transactionSet": "856",
  "senderId": "SUPPLIER123",
  "receiverId": "AMAZON",
  "shipment": {
    "shipmentId": "SHIP12345",
    "orderNumber": "PO56789",
    "shipDate": "2025-10-20",
    "items": [
      { "sku": "B0C2ZNX6T8", "quantity": 10 },
      { "sku": "B0C3LMK5P9", "quantity": 5 }
    ]
  }
}

Response:

{
  "status": "SUCCESS",
  "asnId": "ASN78910",
  "message": "ASN received successfully by Amazon."
}

Advantages of REST EDI:

• Real-time integration (no waiting for batch jobs).

• JSON format — easy for modern applications.

• Better visibility and faster error handling.

---

2. SOAP API in EDI

SOAP APIs are often used in large enterprise systems (like SAP, Oracle EBS, or healthcare systems) where reliability, security, and transaction validation are critical.

Example: Sending an EDI 850 (Purchase Order) through SOAP API

Request (XML):

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
                  xmlns:edi="http://edi.company.com/">
   <soapenv:Header/>
   <soapenv:Body>
      <edi:SendEDIMessage>
         <edi:TransactionSet>850</edi:TransactionSet>
         <edi:SenderID>BUYER001</edi:SenderID>
         <edi:ReceiverID>SUPPLIER001</edi:ReceiverID>
         <edi:Data>
            <edi:PO>
               <edi:OrderNumber>PO12345</edi:OrderNumber>
               <edi:OrderDate>2025-10-20</edi:OrderDate>
               <edi:Item>
                  <edi:SKU>B0C2ZNX6T8</edi:SKU>
                  <edi:Qty>20</edi:Qty>
               </edi:Item>
            </edi:PO>
         </edi:Data>
      </edi:SendEDIMessage>
   </soapenv:Body>
</soapenv:Envelope>

Response (XML):

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
   <soap:Body>
      <SendEDIMessageResponse>
         <Status>Accepted</Status>
         <ControlNumber>000123456</ControlNumber>
      </SendEDIMessageResponse>
   </soap:Body>
</soap:Envelope>

Advantages of SOAP EDI:

• Strong error handling (ACK/NACK within the response).

• Secure (WS-Security, encryption, and digital signatures).

• Reliable delivery (guaranteed message acknowledgment).

EDI 850 (Purchase Order)

What is EDI 850?

The EDI 850 Purchase Order is a transaction set used by a buyer to place an order with a supplier.
It replaces the traditional paper or email-based purchase order and automates the ordering process electronically.

---

Purpose of EDI 850

• Communicate purchase information between trading partners.

• Specify items, quantities, prices, shipping instructions, and payment terms.

• Initiate the Order-to-Cash (O2C) cycle.

---

Who Uses It

• Retailers send 850s to suppliers.

• Manufacturers send them to vendors for raw materials.

• Distributors send them to manufacturers for replenishment.

---

Typical EDI 850 Business Flow

1. Buyer creates a purchase order in their ERP.

2. The system converts it into an EDI 850 format via middleware or VAN.

3. The supplier receives the 850 through their EDI system.

4. The supplier sends back:

   • EDI 855 (Purchase Order Acknowledgment)

   • EDI 856 (Advance Ship Notice)

   • EDI 810 (Invoice)

---

EDI 850 in the Order-to-Cash Cycle

Step	Transaction	Purpose
1	850	Buyer sends Purchase Order
2	855	Seller acknowledges the order
3	856	Seller sends shipment notice
4	810	Seller sends invoice
5	997	Functional acknowledgment for each transaction

---

Benefits of Using EDI 850

• Eliminates manual order entry.

• Reduces errors and processing time.

• Speeds up order confirmation and fulfillment.

• Improves buyer-supplier collaboration.

• Enables real-time order visibility.

EDI Implementation Challenges Every Business Faces

Electronic Data Interchange (EDI) has become the backbone of modern B2B transactions. It automates the exchange of purchase orders, invoices, shipment notices, and more, ensuring faster and error-free business processes. 

However, implementing EDI isn’t always straightforward. Many companies face roadblocks during setup, integration, and partner onboarding. 

Here are the some of the challenges in EDI implementations and practical ways to overcome them.

---

1. Partner Onboarding Complexity

The Challenge:
Every trading partner may have different EDI requirements (formats, versions, and compliance rules). Managing these variations often slows down onboarding.

The Solution:

• Use a standardized onboarding checklist for each partner.

• Invest in middleware or cloud-based EDI platforms that can handle multiple formats (X12, EDIFACT, VDA, etc.).

---

2. Integration with ERP and Legacy Systems

The Challenge:
Mapping EDI data into ERP systems like SAP, Oracle, or Microsoft Dynamics can be complex, especially with older or custom-built systems.

The Solution:

• Use prebuilt ERP connectors provided by middleware tools (Cleo, Seeburger, SAP CPI).

• Automate mapping through drag-and-drop EDI mappers instead of manual coding.

---

3. Compliance and Standards Management

The Challenge:
Different industries (retail, healthcare, logistics) enforce specific EDI standards and regulatory compliance (HIPAA, GS1, ANSI X12, EDIFACT). Staying updated is critical.

The Solution:

• Subscribe to standards update notifications from organizations like ANSI or UN/CEFACT.

• Partner with an EDI service provider that ensures continuous compliance updates.

---

4. Error Handling and Visibility

The Challenge:
When an EDI transaction fails (e.g., missing invoice, incorrect SKU code), it can lead to shipment delays, chargebacks, or lost revenue. Many companies struggle with real-time visibility.

The Solution:

• Implement dashboards with real-time alerts for failed transactions.

• Set up automated acknowledgment messages (997/CONTRL) to confirm receipt.

---

5. High Implementation and Maintenance Costs

The Challenge:
Traditional on-premises EDI systems require significant upfront investment and ongoing maintenance, making them expensive for small and mid-sized businesses.

The Solution:

• Consider cloud-based EDI solutions with subscription models to reduce costs.

• Outsource EDI management to a managed services provider (MSP) if in-house expertise is limited.

Different EDI formats (standards) for exchanging data

EDI (Electronic Data Interchange) has evolved over decades, and different industries, regions, and trading partners use different EDI formats (standards) for structuring and exchanging data. Some of the formats are 

---

1. ANSI ASC X12 (North America)

• Developed by the Accredited Standards Committee (ASC) X12.

• Widely used in the United States and North America.

• Covers multiple industries: retail, healthcare, logistics, government, finance.

• Example: 850 (Purchase Order), 810 (Invoice), 856 (Advance Ship Notice).

---

2. UN/EDIFACT (International)

• Stands for United Nations/Electronic Data Interchange for Administration, Commerce, and Transport.

• Widely used in Europe and globally.

• More internationally accepted than X12.

• Example: ORDERS (Purchase Order), INVOIC (Invoice), DESADV (Advance Shipping Notice).

---

3. TRADACOMS (UK Retail Industry)

• Example: Amazon Vendor Central uses XML EDI over AS2/AS4.

• JSON is often used in API-EDI hybrid integrations.

EDI vs. API: Key Differences in B2B Integration

Both EDI (Electronic Data Interchange) and API (Application Programming Interface) enable data exchange between business partners — but they do it in different ways.

---

What is EDI?

• A standardized format for exchanging business documents (PO, Invoice, ASN, etc.).

• Batch-based: documents are sent in structured files (X12, EDIFACT, VDA).

• Works well for large-scale, regulated industries (retail, healthcare, automotive).

Example: A retailer sends an EDI 850 Purchase Order to a supplier.

---

What is API?

• A real-time communication method between applications.

• Data is exchanged instantly using web technologies (REST, JSON, XML).

• Works best for instant updates (inventory checks, shipment tracking).

Example: An eCommerce site calls a supplier’s API to get livestock availability.
