EDI vs API: Bridge the B2B connectivity gap

To the every-day user, the complexities of the inner workings of a car are deliberately hidden from them. Despite the thousands of individually manufactured components that are, in turn, assembled into larger units, that are then seamlessly brought together as a single working system, the car remains fully under the control of the driver at all times, with only a few easy to learn controls. Here, the complexities of the vehicle are deliberately obfuscated from the user to provide a simpler and more accessible customer experience, allowing the driver to focus on what’s important – the journey.

How does this relate to types of B2B integration?

Manufacturers have continually sought to simplify the complexities of integrating their complex supply chains, removing the need for unnecessary human interactions, and driving for every efficiency available. A key aspect of this approach has been the continued use of Electronic Data Interchange (EDI), an evolving technology that has been the backbone of sharing electronic business documents between trading partners for many decades, and continues to be an effective method of implementing ever closer integration between both customers and their suppliers.

EDI is a standardised, reliable, and proven method of communicating and sharing important trading information across the supply chain, and is used to underpin billions of pounds worth of transactions globally each year. It is an indispensable technology that delivers reduced operating expenses and improved value chain communications to all sizes and types of businesses around the world. Its founding principle is in reducing the complexity of commercial, and logistics challenges that businesses face every day, to free them up to innovate, build markets, and grow revenue.

Getting business done efficiently

EDI allows businesses to get more done, be more productive, facilitate efficient processes, and eradicate the risk of manual errors, by automating business-to-business (B2B) communications. For firms in the automotive, manufacturinglogistics, healthcare, and supply chain sectors, EDI has become a critical tool organisations that manufacture, assemble, transport, buy, and sell goods around the world.

There are significant benefits to the use of EDI as a mechanism of supporting commercial processes between customers and their suppliers:

  • EDI can be quick to implement due to known published EDI standards such as EDIFACT, VDA, ANSI, and TRADACOMS
  • There’s a large and well-established ecosystem of technology providers specialising in the implementation and adoption of EDI services
  • The large variability of software applications in both age and complexity means EDI technologies can easily be used to transform files into different formats and structures to support even legacy systems
  • Exchanging business documents electronically, computer-to-computer significantly improves the overall speed of communications allowing more reliable “Just In Time” exchanges to be realised with greater accuracy
  • With human involvement in the process significantly reduced, errors caused through the manual re-keying of data are dramatically reduced
  • Without the double-handling of business data that sits at the heart of manual processes, increased efficiencies can be seen, with key staff redeployed onto other more strategic activities
  • Closer ties with trusted trading partners will improve relationships and can herald new business opportunities through closer collaboration

EDI challenges

However, EDI can also pose some challenges for IT teams looking for a strategic enabler of supply chain integration and optimisation. Despite the vast business benefits EDI can deliver, many companies have found that it can be labour intensive to maintain up-to-date compliance with trading partner requirements. In addition, the ability to train and retain suitably qualified technical resources, as well as the purchasing and maintaining of EDI software can also pose further problems.

  • EDI experience and appropriate skills are not readily available within the wider integration market space in comparison to other integration approaches, such as APIs, which are routinely understood
  • EDI can be complex to initially set up and may require additional technology, or an ongoing relationship with EDI specialist service providers
  • Different companies tend to use EDI standards in different ways meaning there’s still significant variabilities to support seamless trading between different customers and suppliers
  • Due to its longevity, EDI is seen as yesterday’s technology, despite having a strong track record in enabling B2B integration over many decades

As a result, many companies are exploring other more accessible technologies as an alternative to EDI. Alternatives that can simplify the adoption of EDI and provide a more open framework from which integration is more readily aligned with existing skills commonly available within a business.

Can EDI be replaced by APIs?

In Gartner’s recent report – “Use APIs to Modernize EDI for B2B Ecosystem Integration (June 2019)”– the strategic assumption for B2B integration planning purposes was stated as:

By 2023, over 50% of B2B transactions will be performed through real-time APIs versus traditional approaches.

APIs, therefore, are seen as the growth-enabler for closer integration with trading partners and a mechanism by which information can be shared in real-time, opening up additional integration scenarios. Forward-thinking manufacturers continue to invest in Industrial Internet of Things (IIoT) technologies and continue to explore the use of APIs to extend data sharing, both internally and externally.

APIs are often considered to be more applicable in application-to-application oriented integration scenarios and have some initial benefits over the use of EDI, including:

  • APIs are considered a more modern integration method than EDI, despite EDI having a proven track record in enabling B2B supply chain integration
  • As almost a complete opposite to EDI, API skills are readily accessible within IT circles with almost all IT graduates having the skills to understand and exploit available APIs
  • APIs are typically easy to understand leading to a much faster time to implement and gain value
  • Real-time integration using APIs ensures that systems can be updated immediately, whereas individual EDI transactions are often scheduled for specific times or batched up together
  • APIs can be scaled to millions of transactions with little increase in complexity

API drawbacks

But it’s not all plain sailing, however. Like many technology solutions, APIs also have some drawbacks in comparison to EDI:

  • With little in the way of standards, APIs vary in structure so it can be difficult to manage the variability of structures and capabilities for different APIs
  • Older, legacy applications are rarely compatible with newer API technologies meaning it can be difficult or impossible to use APIs
  • APIs can require more maintenance in the long term in order to deal with new versions and data structures
  • As a more modern integration technique, APIs are not in widespread use for B2B integration in comparison to EDI
  • Security concerns are paramount for the use of APIs, with vulnerabilities being able to be exploited without additional technology to protect the application

With no clear winner, either way, a hybrid EDI/API solution would appear to be the favoured way in which to harness the proven capabilities of EDI while enjoying the accessibility of API technologies. A solution in which some of the complexities of EDI could be simplified using a more modern approach to integration. A solution where the variations of EDI standards and protocols could be reduced to only a single defined set of APIs that could be used to send and receive files between customers and their trusted suppliers?
