List Tunnel Certificates

Deprecated

GET/v1/organizations/tunnels/{tunnel_id}/certificates

Deprecated. This Admin API endpoint is superseded by /v1/tunnels on the Claude API and will be removed after a migration window. New integrations should use /v1/tunnels with the anthropic-beta: mcp-tunnels-2026-06-22 header and a WIF token carrying the workspace:manage_tunnels scope. Existing integrations continue to work with the mcp-tunnels-2026-05-19 header and org:manage_tunnels scope during the migration window.
