CdmVersionApi

  • Rversion finale: Australia
  • Mis à jour 12 mars 2026
  • 10 minutes de lecture

    • The CdmVersionApi provides endpoints that enable you to publish, unpublish, and export versions (snapshots) in Configuration Data Management (CDM) for shared components under shared libraries.

    You publish a snapshot so that it can be exported, enabling the Continuous Integration and Continuous Delivery (CICD) pipeline to access and use the associated shared components and libraries. Exporters can only execute on published snapshots. When snapshots are no longer needed, you can unpublish them to reduce the confusion as to whether the snapshot is viable anymore.

    You must have one of the following roles to access this API:
    • Scripted REST CDM View ACL (sn_cdm.cdm.viewer)
    • Scripted REST CDM Editor ACL (sn_cdm.cdm_editor)

    In addition, the Configuration Data Management (CDM) plugin must be activated for this API to be available in an instance.

    For additional information on snapshots, see View snapshots.

    CdmVersionApi - GET /sn_cdm/versions/export

    Returns the configuration data for a specified shared component within a specified shared library for a specified published version.

    The CDM Editor role is required to access this endpoint.

    URL format

    Versioned URL: /api/sn_cdm/{api_version}/versions/export

    Default URL: /api/sn_cdm/versions/export

    Remarque :
    Available versions are specified in the REST API Explorer. For scripted REST APIs there is additional version information on the Scripted REST Service form.
