}Replace saved SSH credentials
Replaces encrypted authentication without connecting, changing pinned host trust, or rotating the Device identity. Next call connect explicitly with a fresh request key. Do not retry across another credential replacement. REST only; values are write-only.

}Authorizations
Your Reason API key from Settings > API. New keys use reason_; legacy ara_ keys remain accepted. Keys are capability-scoped: run, mcp:read, mcp:write, secrets:read, secrets:write, sessions:read, sessions:debug, knowledge:read, memory:read, memory:write, skills:read, skills:write, repos:read, repos:write, reviews:read, reviews:write, deployment:read, analytics:read, org:read, org:write, attachments:read, attachments:write, guardrails:read, guardrails:write, automations:read, automations:write, agent_auth:read. mcp:write manages MCP server configuration only; it does not authorize remote MCP-tool execution. sessions:debug is privileged: it expands diagnostic session events only for organization owners/admins.
Path Parameters
Organization id or slug. Resolve it with GET /v3/self.
The owned SSH connection id, not its eventual Device id.
Body
- Option 1
- Option 2
