Version history endpoints

Back to the list of all defined endpoints

This endpoint represents the version history that group all related versions.

Whether version history information is accessible depends on versioning.item.history.view.admin configuration If this is set to true, the version history can only be retrieved if the user is a community, collection or repository administrator, otherwise the version histories are public. Please note that the security of the version history is in no way related to any of the items that belong to it. It is eventually possible to retrieve an history containing only not accessible items. As the version history neither the single version expose any sensitive information this pose no security risks.

draftVersion

GET /api/versioning/versionhistories/<:versionHistoryId>/draftVersion

If the latest version is not yet archived, provide access to the workspaceitem or workflowitem associated with it. The link will respect the security defined in the workspaceitem or workflowitem endpoint so it could be not visible to user otherwise allowed to create a new version in the history. For this scenario the draftVersion flag allows the UI to turn off the "create new version" button. Due to the restriction applied to this flag anonymous users will be unable to discover that a new version is currently under review.
