About Consuming webservices from my IBM i System
This module will explain the basic concept of talking to an internet web services from the IBM i system, and getting responses back. We have various techniques for reading (consuming) webservices out there on the Internet or on any remote network. Here we will look at various techniques to consume internet webservices from our IBM i Power System.

Good Question! Let's discuss the various ways an RPG program can be written as A WEBSERVICE to share information with any requesters on the internet.
If you are using the IBM i HTTPAPI (LIBHTTP) opensource utilities, you already realize how easy it is to talk to an internet web service from within your IBM i RPG programs but sometimes even the best-laid plans go wrong. This is when you need to learn how about the “debug HTTPAPI webservices” function.
Consuming Webservices with native IBM i SQL

IBM comes with pre supplied SQL functions - the SQL integration in IBM i makes connecting to external webservices so simple you will slap yourself.
How about we write a super simple SQL statement to connect to an internet webservice and get a little bit of JSON back as a reply? Then we can wrap that super simple SQL statement in an SQLRPGLE program that is nearly as simple? Ready? Let's Gooooo
