API Toolkits for IBM i by Kato Integrations - a developer’s best friend. These toolkits work as a library of RPG utilities and subprocedures, designed to help streamline your integrations with APIs around the globe. Each one is built using 100% RPG, meaning it ties closely to the IBM i operating system, promoting both accelerated development and lightning fast processing.
All toolkits let you develop using only RPG
Keep security at the front line of your development
No Java, middleware, or external dependencies
Your solution is backed by RPG experts
Connect to APIs with a library of subprocedures

100% Native RPG: Utilize powerful subprocedures programmed in RPGLE – to perform accurate, real-time address validation for as little as $0.005 per lookup.
Leverage the UPS Developer Kit API to communicate in real-time with shipping and package tracking services, address validation, and estimating time in transit and delivery.
CyberSource Toolkit for i allows you to quickly implement credit card processing functionality in new or existing business applications on IBM i, utilizing the popular CyberSource payment gateway.

The API Toolkits are pre-built, purpose-specific integration solutions written in 100% RPG — one each for address validation, UPS shipping, and CyberSource credit card processing. Where RPG API Express is a general-purpose toolkit for building any API integration, the toolkits are ready-to-deploy solutions for those three specific use cases. If your integration need matches one of the available toolkits, implementation is significantly faster than building from scratch. The toolkits use the same 100% RPG, TLS-secure approach as RPG API Express and are backed by the same expert team.
The Address Toolkit validates postal addresses in real time against USPS and international address databases, using native RPGLE subprocedures. It verifies customer addresses before they’re stored in your system — catching errors at the point of entry rather than discovering them when mail is returned or deliveries fail. Lookups cost as little as $0.005 each, making it cost-effective even at high volumes. For IBM i shops managing customer databases, order processing, or any workflow where address accuracy affects operations or delivery, the Address Toolkit eliminates a common source of downstream errors.
The UPS Toolkit connects your IBM i directly to UPS online services in real time. Capabilities include rate comparison, transit time estimation, shipping label creation, return shipment processing, international shipping, address validation, and package tracking — all accessible from RPGLE programs. Labels can be printed directly from the IBM i to a compatible ZPL label printer. All data is transmitted using TLS encryption in compliance with current PCI standards. For distributors, manufacturers, or any IBM i shop processing shipments, the UPS Toolkit eliminates the manual steps between your IBM i and carrier services.
The CyberSource Toolkit integrates IBM i applications with the CyberSource payment gateway for credit card processing. It supports authorization and capture transactions, TLS encryption and credit card tokenization for PCI-compliant handling of cardholder data, and EMV chip card transactions for in-person payment processing. For organizations running point-of-sale, order management, or billing workflows on IBM i that need to process payments securely, the CyberSource Toolkit provides a production-ready implementation without building the payment integration from scratch.
The toolkits are built using the same RPG-native approach as RPG API Express and are designed to integrate cleanly with your existing RPGLE programs. Contact Kato to confirm specific prerequisites for the toolkit you’re evaluating, as requirements may vary by toolkit. Kato’s team can also advise on the fastest path to implementation for your specific environment.
Yes. If your integration need isn’t covered by the existing toolkits, Kato’s Professional Services team can build a custom solution using RPG API Express. Kato has implemented hundreds of API integrations across REST and SOAP environments, and the proof of concept process is the starting point for scoping custom work. If there’s a specific API you need to connect to, it’s worth a conversation with the team to assess feasibility and timeline.
