Integrating IBM i with Third Party and E-Commerce Platforms

IBM i applications are robust and secure compared to other applications. There’s no limit to what you can achieve with AS400 when you integrate with the right third party technologies. For example, warehouse management systems, CRMs, security applications, EDIs, or any cloud services, like Amazon Web Services (AWS).

The same applies to integration with Magento e-commerce integration. If you have your online marketplace built up on IBM i, integration with Magento streamlines the online purchasing process while IBM i continues to process
transactions safely, securely, and quickly.

IBM i API Integration

Looking for API integration with your IBM i system? is here for you.

Integration using Java

Java is one of the most reliable options to integrate APIs into IBM i systems because it

  • Supports both SOAP and REST API.
  • Easily manipulates complex requests and responses.
  • Handles XML better than RPG.
  • Handles multimedia formats (like files and images).
  • Can be used as a wrapper to upload API content
  • Calls RPG programs from Java to perform business logic.

Integration using IBM i tools

  • Uses open source tools like the LibHTTP to call external API.
  • Incorporates IBM i, Db2 SQL functions to make HTTP calls directly from SQL statements.
  • IBM i Db2 SQL functions are used to parse the information received by HTTP calls and stores them in relational tables in Db2.

Why So Many Companies Still Use AS400/IBM i

For years, organizations and even some technology experts have considered AS400 obsolete. However, when we look at the facts, including the characteristics and the importance of this system in its updated format today, we discover that AS400 cannot be ignored. Today, it is still one of the most integral systems for enterprises, manufacturing industries, finance and more.

For years, organizations and even some technology experts have considered AS400 obsolete. However, when we look at the facts, including the characteristics and the importance of this system in its updated format today, we discover that AS400 cannot be ignored. Today, it is still one of the most integral systems for enterprises, manufacturing industries, finance and more.

As we already know, AS400 systems now includes an extensive library-based operating system. IBM i, it is also capable of supporting multiple instances of AIX, Linux, Lotus Domino, Microsoft Windows 2000 and Windows Server 2003. The Power processors support IBM i, AIX, Linux and Lotus Domino. Windows is supported with either single-processor internal blade servers (IXS) or externally linked multiple-processor servers (IXA and iSCSI). iSCSI also provides support for attachment of IBM Blade centres. Windows, Linux, and VMware ESX(VI3) are supported on iSCSI attached servers.

Other important features include:

  • Logical portioning
  • DB2 Mirror
  • Common client-server support

RPGLE-the most secure and robust language

RPGLE or RPG IV is the latest version used for IBM i application development. Although companies are migrating to new platforms, there are ways of migrating the frontend to new platform keeping the old RPG code intact. This includes some simple and easy procedures:

  • One of the simple solutions is re-facing or transforming the green screen into a GUI. Re-facing makes the interface user friendly giving a browser-based look and feel without any programming changes.
  • The common green screen can be enhanced by using RPG Open Access to separate the business logic from the UI, allowing the same business logic to be used on multiple UIs.

Benefits of IBM i development from PIO

  • Our programmers have in-depth knowledge of a variety of tools and have a wealth of technological expertise.
  • They follow functional specifications to create technical documentation and develop pseudo codes.
  • They troubleshoot your business processes to diagnose where the issues are.
  • They will help your enterprise modernize legacy code, integrate your ERP or EDI solutions, as well as develop and maintain applications.
  • If you need support for existing software, they can help debug, locate and solve issues.
