Hear from our customers

With the help of RPG API Express I was able to cut my personal project time in half. RPG API Express is a proven toolset that allows for easy creation of JSON web services from RPG. I’d recommend it to anyone on the IBM i / AS400 platform because it runs natively in RPG with Apache giving it excellent performance!

Utilizing RPG API Express with great guidance from the Krengeltech support team we successfully consume UPS web services to create electronic return labels. This is the best package support I’ve received from my 15 years of IBM i/AS400 experience.

RPG API Express enables us to communicate from our IBM i in real-time with our credit vendors, and the implementation was quick and easy. I would recommend it to anyone.

I followed some example code on your website and have a simple app up and running very similar to what my client needs. I just need to adapt it to their JD Edwards World Database. Your software is making me look like a hero!
