Introduction to EDI and API
Two common integration methods that have gained significant popularity in recent years are Electronic Data Interchange (EDI) and Application Programming Interface (API). While both EDI and API serve the purpose of data exchange between disparate systems, they have some key differences that businesses need to understand.
Whereas EDI facilitates the exchange of structured business data among the EDI systems of trading partners, while APIs enable integration and communication between diverse software applications, facilitating real-time data exchange.
Contemporary B2B onboarding processes demand adherence to data formats such as EDI and protocols like AS2 or SFTP. However, modern IT onboarding extends beyond this, encompassing the deployment of new cloud or on-premise applications, often necessitating additional APIs. That’s why businesses today are looking for a more centralized integration platform that can use both technologies EDI and API together to enhance the overall B2B data transmission process.
Key Takeaways

What is EDI (Electronic Data Interchange)?
EDI, or Electronic Data Interchange, is a method that enables the exchange of business documents between different computer systems. It has been in use for several decades and has proven to be a reliable and secure way of transmitting data electronically. EDI follows a standardized format, such as ANSI X12 or EDIFACT, which ensures that the data is structured and can be easily interpreted by the receiving system.
One of the main advantages of EDI is its ability to automate manual processes and reduce human error. By eliminating the need for manual data entry, businesses can save time, minimize costs, and improve accuracy. EDI is commonly used in industries such as retail, manufacturing, and healthcare to exchange purchase orders, invoices, shipping notices, and other business documents.
What is API (Application Programming Interface)?
API, or Application Programming Interface, is a set of rules and protocols that allows different software applications to communicate with each other. APIs enable seamless integration between systems, enabling them to share data and functionalities. Unlike EDI, which focuses on the exchange of structured data, APIs are more versatile and can transmit both structured and unstructured data in real-time.
APIs have gained immense popularity in the digital age due to their flexibility and ability to facilitate real-time interactions. They are widely used in various industries, such as e-commerce, finance, and social media. For example, when you book a flight ticket on a travel website, the website uses an API to communicate with the airline’s reservation system and retrieve the available flights and prices.
EDI vs API: Understanding the Key Differences
Now that we have a basic understanding of EDI and API, let’s delve into the key differences between these two integration methods.
Data Structure
EDI relies on a standardized data format, which ensures that the data is consistent and easily interpreted by the receiving system. On the other hand, APIs are more flexible and can handle both structured and unstructured data. This makes APIs suitable for real-time interactions and enables businesses to exchange a wide range of information.
Real-time vs Batch Processing
One of the primary distinctions between EDI and API is the way they handle data transmission. EDI follows a batch processing approach, where data is exchanged periodically in predefined batches. This can introduce delays in data transmission and processing. On the contrary, APIs facilitate real-time communication, allowing data to be transmitted instantly and enabling businesses to access up-to-date information.
Integration Complexity
EDI integration typically requires specialized software and expertise to set up and maintain. The process involves mapping data fields, establishing communication protocols, and ensuring compatibility between systems. Conversely, API integration is relatively simpler, as it leverages widely adopted web technologies such as REST or SOAP. APIs provide well-documented endpoints and methods, making it easier for developers to integrate systems and exchange data.

EDI vs API: Industry Use Cases and Examples
Now let’s explore how EDI and API are used in different industries and examine some real-world examples.
Retail Industry
In the retail industry, EDI is commonly used for automating the exchange of purchase orders, invoices, and shipping notices between retailers and suppliers. This streamlines the procurement process, reduces errors, and improves order fulfillment efficiency. APIs, on the other hand, enable retailers to integrate their e-commerce platforms with payment gateways, logistics providers, and inventory management systems in real time. This allows for seamless order processing, inventory updates, and payment processing.
Manufacturing Industry
In the manufacturing industry, EDI plays a crucial role in supply chain management by enabling the exchange of production forecasts, delivery schedules, and shipping instructions between manufacturers and suppliers. This improves production planning, reduces lead times, and enhances collaboration between trading partners. APIs are used to integrate manufacturing execution systems (MES) with enterprise resource planning (ERP) systems, enabling real-time visibility into production processes, inventory levels, and order status.
Healthcare Industry
In the healthcare industry, EDI is widely used for claims processing, eligibility verification, and electronic remittance advice (ERA). This automates administrative tasks, reduces paperwork, and speeds up the reimbursement process. APIs are utilized to integrate electronic health record (EHR) systems with laboratory information systems, pharmacy systems, and telemedicine platforms. This ensures seamless data exchange, improves care coordination, and enables interoperability between healthcare providers.
These are just a few examples of how EDI and API are leveraged in different industries. The key takeaway is that both integration methods have their unique strengths and applications, and businesses need to assess their specific needs before deciding which method to adopt.
Conclusion
Understanding the key differences between EDI and API is crucial for businesses looking to optimize their data exchange processes. While EDI offers structured data transmission and batch processing capabilities, APIs enable real-time interactions and flexibility in handling different data types. By leveraging the strengths of both integration methods, businesses can achieve seamless connectivity across their systems, enhance collaboration with trading partners, and accelerate their digital transformation journey.
Whether you choose EDI, API, or a combination of both, it is important to align your integration strategy with your business goals, technical capabilities, and industry standards. By doing so, you can unlock the potential of EDI and API and harness their power to drive business success.
