The Differences Between EDI and API
In the world of big data, two main systems exist that specialize in transmitting large amounts of data across partners and companies. These two systems have different capabilities and methods of achieving this goal but they essentially aim to fulfill the same function: getting data to and from two or more recipients.
In this article, we’ll discuss the differences between EDI and API as we dive into each protocol’s pros and cons. By analyzing each, you can determine which protocol would best fit your big data needs.
EDI stands for Electronic Data Interchange and has been around since as early as the 1970s. EDI works by first establishing a connection to a secure, reliable peer-to-peer (P2P) network. It standardizes data from large quantities of physical documents and processes the information into an electronic format.
EDI is a staple in the world of logistics because it minimizes labor, time, and reduces the risk of inaccurate data from illegible handwriting or incorrect documents being processed manually.
- Security – Systems using EDI protocol are known for their robust security and privacy settings, allowing companies to rest assured that their trade secrets and confidential information cannot be hacked or stolen. EDI opens a secure connection between only two parties and allows each party to send and receive information once set-up is complete. Users control which information is sent and data is protected so that only predefined authorized users may access it.
- Ease of use – EDI takes an antiquated practice of manual document processing and flips it on its head using technology to streamline data collection and transmission. What used to take hours of manual labor can be done a fraction of the time, thereby freeing up manual labor and driving down costs. EDI specialists are abundant and can teach users how to be up and running within a few months.
- Accessibility – Due to its popularity, EDI has become an industry standard and any business looking to adopt EDI technologies will find that many partners are already set up with EDI.
- The number of versions – EDI systems have 3 specific versions, and versions must match between two partners. Outdated versions are not compatible with each other so if a supplier has a different version, they must upgrade before integration.
- Limited Scope between Partners – EDI functions as an open channel between only two parties. To include another partner, another EDI connection must begin and essentially start from square one to make sure all parties have compatible versions. Also, both parties must accept the same transmission guidelines to complete integration, including methods, translations, and standards of data.
- Outdated Technology – EDI uses technology that is quickly becoming outdated. EDI has a history of minimal updates and only made revisions to its software 30 years after its inception. Because of this, EDI will not be compatible with future technologies such as blockchain and may hinder progress for some companies looking to invest in newer systems. Also, transmission times may vary depending on the amount of data. Times may range between 30 minutes to 2 hours if the scope of data is particularly large.
- Cost – EDI is not cheap. This is due to the time it takes to synchronize systems and train employees. EDI projects may last from 3-6 months before full functionality can be achieved, and while customization may offer more data control, this still requires manual intervention. EDI specialists usually must be sought after separately, and their associated costs may rise quickly.
Now let’s see how API, the new kid on the block, compares to EDI…
API, Application Programming Interface, performs the same function but in a significantly different manner.
While EDI establishes a connection between two EDI systems, API is a web-based protocol that allows different systems to communicate with each other. Using cloud-based technology, API allows for data to flow in less than a second between systems. This real-time access to big data is showing promise as many industry giants such as Amazon have already incorporated API into their supply chain.
Universal transmission and automation also make up another major difference to EDI, meaning human intervention is practically nonexistent while using API.
- Faster Data – API is a powerhouse when it comes to accumulating data because it is not dependent on manual users uploading documents. Using IoT technology, API connects systems and continually updates information and data as it becomes available. EDI’s transmission time pales in comparison to API’s instant and accurate data accrual. What takes EDI 30 minutes to 2 hours to upload, API can perform in minutes. API also allows pickup requests to be input automatically rather than manually. This data accessibility will allow users to respond faster to issues and make accurate projections about their materials and products.
- Simplicity – API simplifies data transmission and allows users to gather data without the need for customization. Also, the need to match versions between two parties is nonexistent because API connects systems that are already in place, such as TMS, WMS, and ERP.
- Future Technology Compatibility – Part of the allure of API is that it is software that anticipates new technologies. As future technologies roll out, API systems can support them and become compatible, further accelerating its capacities and visibility among the supply chain. For example, blockchain technology allows for every user of the supply chain to witness all transactions happening in real-time, giving maximum visibility and discouraging any sort of unethical practices. While it’s not yet perfected, taking advantage of future technologies is something to consider if you want to invest in a system that will continue to improve.
- Newer Technology – API is a relatively new player and is not as popular as EDI among industries. As with any new technology, there will initially be more EDI users who refuse to adapt and stick with traditional software. This may affect your decision if a partner currently uses EDI and does not want to switch to API just yet.
- Lack of Security – API is software-dependent on the web, meaning it’s much more susceptible to hacking and data breaches than EDI. Due to its connectivity to many systems, a data breach could potentially mean that all of your systems are compromised.
- Reliant on an internet connection – While the internet has become as commonplace as oxygen, unforeseen connectivity problems happen. API lies at the mercy of a stable internet connection, and any interruptions can affect every system connected via API. As anyone in the industry can attest to, when the system is down, nothing gets done.
Business leaders may look to invest in API to take advantage of its speed and connectivity over multiple systems. EDI continues to be the primary system for data transmission, but that may change in the next decade. Knowing the pros and cons of each system will help you determine which system will better serve your company’s needs.
