# List Tunnel Certificates

**GET** `/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**Deprecated.** This Admin API endpoint is superseded by `/v1/tunnels` on the Claude API and will be removed after a migration window.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`](/docs/en/api/beta/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.

List the certificates registered on a tunnel.

Archived certificates are excluded unless `include_archived` is set.

## Path parameters

- `tunnel_id: string`

  ID of the Tunnel.

## Query parameters

- `include_archived: optional boolean`

  Include archived certificates in the results. Archived certificates are
  excluded by default.

  default: false

- `limit: optional number`

  Maximum number of certificates to return.

  default: 20, maximum: 1000, minimum: 1

- `page: optional string`

  A tunnel has at most two active certificates, so this list is not
  paginated.

## Headers

- `"anthropic-beta": array of AnthropicBeta`

  Optional header to specify the beta version(s) you want to use.

  - `string`

  - `"message-batches-2024-09-24" or "prompt-caching-2024-07-31" or "computer-use-2024-10-22" or 42 more`
