Now Available: Consuming REST APIs in COBOL/Batch applications

[Kim Peelman]

We are pleased to announce our most recent addition to Gen v8.6: Consuming REST APIs for COBOL/Batch applications. With this functionality, your Gen applications can consume information available via RESTful services. Many customers are excited for this opportunity to:

• Create seamless interactions between applications.

• Offer enhanced functionality with access to real-time data.

• Modernize user experiences and enterprise infrastructure. 

***BONUS: This publication also enables consuming REST APIs for applications in Compatibility Mode (CICS and COBOL/Batch). This was a request submitted in through the Community Ideas HERE. ***

You can find the solutions here: 

• Gen Solutions List (mainframe)

• See "CONSUMING RESTFUL APIS" for LU08865, LU08866, LU08867

 

For more information: 

• Tech Docs: Add a Call REST Statement and OpenAPI Spec Caveat for Gen

• Knowledge Articles: Gen 8.6 Consuming REST APIs (Call REST) feature. 

• View the web-based training videos HERE.

  • Functionality is similar to what we published for Consuming REST in CICS and Java applications in 2022 (announced here).

Scope includes: 

• Consuming RESTful services for COBOL/Batch applications

• includes methods: Get, Post, Put, Delete

• includes DB2 Attach Types: DB2_DSN, EXEC (or NONE)

• includes support for applications IN COMPATIBILITY MODE

• includes support for Security Schemes: BasicAuth, BearerAuth, ApiKeyAuth, Oauth2-Client Credential Flow

• includes configuration parameters to allow certain settings to be dynamically set in your PAD logic

• Consuming RESTful services for CICS applications IN COMPATIBILITY MODE.

• This functionality without Compatibility Mode is already published in January 2022. You can learn more in the community announcement HERE. 

Coming Soon*: 

• DB2 Attach Types: DLIBATCH and IMS_BMP

• the capability to specify configuration overrides in a file, similar to the callrest.properties file for Java applications

• support for TSOAE for testing

It is our intent to expand to other languages/platforms, add additional methods, and provide further enhancements based on user feedback. Within the "Add a Call REST Statement" documentation on TechDocs is a section called "OpenAPI Spec Caveat for Gen". This documentation describes the constructs within an OpenAPI specification that Gen does not support.  We're eager to hear what functionality you want next. Please send feedback to me: [e-mail] or post in the Ideas section for Gen. 

*This is a forward-looking statement. This is subject to change at any time without notice.  The development, release, and timing remain at Broadcom's sole discretion.
