Reference information for the Domino platform’s public REST API endpoints, including the Tags and Properties endpoints. Some APIs have their own reference sections, listed alongside this one. The Governance and Workspace File Audit Trail APIs are documented separately because each is served by its own service.

Open https://<your-domino-domain>/docs to browse the Nucleus OpenAPI specification in a Scalar interface. The reference lists the available operations, request parameters, and response schemas. The 6.3 API Catalog covers Nucleus only. APIs served by other Domino services, including the Governance and Workspace File Audit Trail APIs, aren’t included in this interface.

Start a user’s Workspace as an administrator

The Nucleus API includes an adminStartWorkspace operation for starting a stopped Workspace that belongs to another user. The caller must have the ManageWorkspaces permission. Domino starts the Workspace as its owner and retains the external data volume and NetApp Volume mounts from its most recent session. This operation starts only a Workspace in the Stopped state. To automate a restart, first stop the Workspace with the existing stop operation, wait for it to reach Stopped, and then call adminStartWorkspace. By default, Domino returns an error when the owner’s temporary credentials are expired. Set ignoreExpiredCreds to true in the optional request body to start the Workspace without mounting those expired credentials.
