IBM will host a Virtual Wildfire Workshop for:
Accessing REST APIs from z/OS using IBM z/OS Connect

February 27, 2024

This event will be both presentation and hands-on labs.
Registration ends Feb 23



Cloud applications are reshaping the way enterprises and systems interact. The dominant standard for application development for these new environments for accessing remote resources uses RESTful APIs for sending and receiving JSON formatted messages. IBM z/OS Connect Enterprise Edition provides a framework that enables access from z/OS COBOL applications to remote RESTful APIs using JSON messages with a minimum of COBOL programming required.

This workshop provides an overview of RESTful APIs and instructions on how to develop COBOL applications than can access remote REST APIs. Details of the application programming requirements will be covered for APIs documented using either OpenAPI2 or OpenAPI3 specification.

When requested, attendees will be given the opportunity to perform exercises using z/OS Connect OpenAPI2 tooling to develop application artifacts and the coding practices for accessing remote APIs from COBOL application running in MVS Batch, CICS and IMS TM. The exercises will use IBM Cloud images which have the development tooling already installed and configured. Attendees will be able to perform the exercise from their own device for a limited time after the online portion of the workshop has completed. No software is required to be installed on an attendee’s device. IBM proctors will be available to provide guidance and assistance to help attendees get started with performing the exercises. The exercises are intended to be self-paced.
Access to the images can be requested at later time by contacting your local IBM representative.
