  • 1.  z/OS Connect 3 API Requester, Open API 3 support?

    Posted Thu March 19, 2026 09:48 AM

    Hi

    We have for the last year been creating API requesters based on Open Api 3.0.2 specifications.

    But now we have gotten a requirement where we need to create an API Requester where the specification/contract is OpenAPI 3.1.1

    I'm getting the following 'message' when i try to run the API Requester gradle plugin.

    Invalid OpenAPI Document

    FAILURE: Build failed with an exception.

    • What went wrong:
      Execution failed for task ':generateApiRequester'.
      > BAQP0034E: The OpenAPI document is in error. Reason: Illegal character in opaque part at index 2:

    Does IBM only support OpenAPI 3.0 and not OpenAPI 3.1 the API Requester gradle plugin?

    Hello Tore,

    I'm pleased to hear you have been creating API requesters and using the Host API capability to call them. For your requirement to call OpenApi 3.1.1 defined APIs; please can you vote on this idea that we currently have open IBM z/OS Connect 3.0 support of a OpenAPI 3.1 | IBM Z Software to satisfy the requirement?

    Kind Regards,

    Mark
