Create Tunnel Certificate
POST /v1/organizations/tunnels/\{tunnel_id\}/certificates
Deprecated
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 This Admin API endpoint is superseded by /v1/tunnels on the Claude API and will be removed after a migration window.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.
Register a public CA certificate for the tunnel.
Anthropic verifies the gateway's server certificate against this CA when it terminates the inner TLS session. The PEM body must contain exactly one X.509 certificate and no private-key material. A tunnel holds at most two non-archived certificates.
Path parameters
tunnel_id: stringID of the Tunnel.
