Accessing REST APIs from z/OS using z/OS Connect (API Requester)

Overview

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.

Concurrent with the session, a limited number of 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.

Objectives

At the conclusion of this workshop, an attendee should have the basis for:

  • Using the z/OS Connect tooling to generate the COBOL copy books representing the API’s request and response messages.
  • Understanding the COBOL coding requirement for using the z/OS Connect interface stub to build request message and process response messages using the z/OS Connect API requester client REST interface.
  • Understanding the requirements for providing security credentials from the client to the API provider endpoint from the application.

Agenda

  • Welcome and Introduction
  • Presentation – An introduction to IBM z/OS Connect API requester topics.
    • Using z/OS Connect tooling to generate COBOL copy books.
    • COBOL coding requirements for communication with the z/OS Connect server.
    • COBOL coding options for providing security credentials.

Exercises (accessible after the workshop)
The exercises for developing COBOL application to access remote APIs:

  • Developing CICS API Requester Applications (OpenAPI 2)
  • Developing IMS API Requester Applications (OpenAPI 2)
  • Developing MVS Batch API Requester Application (OpenAPI 2)

Date/Time

August 14th, 2024 | 9:00 – 11:30, 1:00 – 4:00 ET

The WebEx portion of the workshop will start at 9:00 a.m. and end at approximately 11:30AM.
An optional afternoon session will start at 1:00 PM and address any outstanding items and/or questions and will transition to the exercises. Assistance will be provided to address questions or issues that attendees may encounter.

Audience

This workshop is designed for application developers, system administrators and enterprise architects who are involved with the administration and support of their z/OS Connect environment.
