Today many companies, be they small-scale firms or medium to large-scale industries are adopting the use of EDI technology to streamline their communication process. EDI helps exchange business documents between organizations via the use of communication protocols.
Think of EDI protocols as a software language like HTML, JavaScript, or any other computer language. EDI protocols are software formats used for sending and receiving data. These protocols define how the EDI data is transmitted, authenticated, and secured during transmission. To exchange EDI data successfully businesses must use the same EDI protocols at both ends unless the businesses are using a third-party VAN provider that acts as a middleman, translating EDI messages between protocols and partners while enabling you to use your own, single protocol no matter which protocols your partner use.
A VAN is a third-party service provider that acts as a hub to facilitate EDI data transmission between trading partners. The VAN provides the infrastructure, security, and support needed to transmit EDI data between partners. VAN also provides evidence of the delivery and processing of EDI messages at the destination. The advantage of using a 3rd party VAN is it acts as a middleman, translating EDI messages between protocols and partners while enabling you to use your own, single protocol no matter which protocols your partner uses.

FTP was developed in the early 1970s to allow the transfer of files between computers on different networks. FTP is a standard network protocol used to transfer files from one host to another over the internet. FTP is a simple and reliable method for transmitting EDI files.FTP uses a client-server model, where the client sends requests to the server to download or upload files. The client can be any device such as a personal computer, tablet, or smartphone, while the server is a dedicated computer that stores the files and responds to client requests.
FTP uses two channels, a control channel and a data channel, for transmitting files. The control channel is used to send commands and responses between the client and the server, while the data channel is used to transmit the files themselves. It supports various authentication methods such as usernames and passwords, public and private keys, and SSL/TLS encryption. FTP is widely used to transfer large files between different systems.
FTP is a straightforward protocol that can be easily used by anyone with basic computer skills. The client software is readily available and simple to use, and most web browsers also support FTP.
FTP is supported by most operating systems, including Windows, macOS, Linux, and Unix, as well as many web browsers and mobile devices.
Large file transfer: It can handle large files and can transfer files over a network at high speeds, making it suitable for transferring large amounts of data.
It can be used in different ways, including anonymous file sharing, user authentication, and secure file transfer using encryption protocols such as SSL/TLS.
FTP allows remote access to files stored on a server, enabling users to upload or download files from anywhere in the world, if they have an internet connection.
FTP is a cost-effective method for transferring files, as it does not require expensive software or hardware and can be easily set up using free or open-source software.
FTP is not a secure protocol, and the data being transmitted can be intercepted or modified by third parties. Therefore, it is recommended to use secure variants of FTP such as SFTP (Secure File Transfer Protocol) or FTPS (FTP over SSL/TLS) that provide encryption and authentication to ensure secure file transfer.
FTPS (File Transfer Protocol over SSL/TLS) is a secure variant of FTP (File Transfer Protocol) that provides encryption and authentication for file transfer over a network. FTPS uses SSL/TLS (Secure Sockets Layer/Transport Layer Security) to encrypt the FTP connection, ensuring that the data transmitted between the client and server is protected from unauthorized access or interception.
FTPS can use either explicit or implicit SSL/TLS encryption. In explicit mode, the client establishes a regular FTP connection to the server and then negotiates SSL/TLS encryption. In implicit mode, the FTP connection is encrypted from the beginning, without the need for explicit negotiation. FTPS supports a range of encryption algorithms and key lengths, providing a high level of security for file transfer. It can also support user authentication using various mechanisms, including password-based authentication, public-key authentication, and certificate-based authentication.
FTPS is widely supported by FTP client and server software, making it a popular choice for secure file transfer over a network. However, because FTPS still relies on the FTP protocol, it may not be suitable for all use cases, particularly those that require high-speed or real-time data transfer.
FTPS provides encryption and authentication of data transfer, ensuring that the data transmitted between the client and server is secure and protected from unauthorized access or interception.

REST (Representational State Transfer) API, also known as RESTful API, is a type of API (Application Programming Interface) that is designed to be used with web services. It is a popular architectural style for building web services, and it is based on the HTTP (Hypertext Transfer Protocol) protocol.
REST API is designed to allow clients to access and manipulate web resources using a set of well-defined operations, including GET, POST, PUT, and DELETE. These operations correspond to the CRUD (Create, Read, Update, and Delete) operations commonly used in database applications.
REST API is a powerful tool for building web services that can be used across different platforms and programming languages. It is widely used in modern web applications and is a key component of the web services architecture.
REST API can help to facilitate EDI (Electronic Data Interchange) by providing a modern and flexible way to exchange business documents between trading partners. Traditional EDI systems rely on proprietary protocols and complex data formats that can be difficult and expensive to implement and maintain.
By using REST API for EDI, trading partners can leverage the benefits of web services and the HTTP protocol to exchange data in a more efficient and standardized way. REST API can also provide a simpler and more flexible approach to data mapping and transformation, allowing trading partners to exchange data in a variety of formats and protocols.
One of the key advantages of REST API for EDI is that it can be easily integrated with other systems and applications, including ERP (Enterprise Resource Planning) systems, CRM (Customer Relationship Management) systems, and other business software. This makes it easier to automate business processes and reduce manual data entry and processing.
REST API can also help to improve the speed and accuracy of EDI transactions, as well as increase visibility into the supply chain. With real-time data exchange and tracking, trading partners can more effectively manage inventory levels, production schedules, and customer orders.
The client and server are separate entities that communicate with each other using standard HTTP methods.
The server does not store any client context between requests, which simplifies the server design and allows for greater scalability.
Responses to client requests can be cached to improve performance.
REST API allows for the use of intermediaries, such as proxies and gateways, to improve scalability and security.
REST API defines a uniform interface between the client and server, which makes it easier to develop and maintain web services.
RESTful APIs are built on HTTP protocol, which can lead to challenges with scalability and reliability when scaling up to handle high-volume requests.
RESTful APIs are not ideal for more complex operations such as transactions that require multiple steps or multi-object queries.
RESTful APIs rely on HTTP for authentication and encryption, which can be vulnerable to certain attacks like session hijacking, cross-site scripting, and cross-site request forgery.
There is no standard format or structure for RESTful APIs, making it difficult to implement them in a uniform manner across different platforms and programming languages.
RESTful APIs can suffer from performance issues when handling large or complex datasets, as they can require multiple requests to retrieve all the necessary data.
RESTful APIs are stateless, which means they don’t store any session information, and each request is treated as a new request. This can be a challenge when dealing with applications that require state management.
