Resume a session

POST/v1/sessions/{session_id}/resume

Restart a stopped, failed, or expired session. Suspended live sessions resume automatically when work arrives, so this is only needed after a terminal state.

Generated from the Platform API specification on 2026-09-04.

Path parameters

Parameter	Type	Description
session_id	string	The session, as returned by Create a session.

Headers

Header	Required	Description
Authorization	yes	Bearer plus a short-lived OAuth access token issued for the Tanomis API audience. Backends obtain tokens with an organization automation client; the CLI’s human login is not an application credential.
X-Organization-ID	yes	The organization_id from the workspace projection you selected in GET /v1/me/workspaces.
X-Workspace-Tenant-ID	yes	The nested tenant_id from the same projection. A header cannot widen what the token grants. Some single-workspace or self-hosted environments take X-Tenant-ID instead, as supplied by their administrator.

Responses

Status	Meaning
200	The session, ready again.
404	No such session in the selected tenant.
409	The session is not in a state that can be resumed.
