Follow this guide to set up a Cloudflare Tunnel using the API.

## Create an API token

[Create an API token](https://developers.cloudflare.com/fundamentals/api/get-started/create-token/) with the following permissions:

| Type | Item | Permission |
| - | - | - |
| Account | Cloudflare Tunnel | Edit |
| Zone | DNS | Edit |

## 2. Create a tunnel

Make a `POST` request to the [Cloudflare Tunnel](https://developers.cloudflare.com/api/resources/zero_trust/subresources/tunnels/subresources/cloudflared/methods/create/) endpoint:

Required API token permissions

At least one of the following [token permissions](https://developers.cloudflare.com/fundamentals/api/reference/permissions/) is required:

* `Cloudflare One Connectors Write`
* `Cloudflare One Connector: cloudflared Write`
* `Cloudflare Tunnel Write`

```bash
curl "https://api.cloudflare.com/client/v4/accounts/$ACCOUNT_ID/cfd_tunnel" \
  --request POST \
  --header "Authorization: Bearer $CLOUDFLARE_API_TOKEN" \
  --json '{
    "name": "api-tunnel",
    "config_src": "cloudflare"
  }'
```

```sh
{
  "success": true,
  "errors": [],
  "messages": [],
  "result": {
    "id": "c1744f8b-faa1-48a4-9e5c-02ac921467fa",
    "account_tag": "699d98642c564d2e855e9661899b7252",
    "created_at": "2025-02-18T22:41:43.534395Z",
    "deleted_at": null,
    "name": "example-tunnel",
    "connections": [],
    "conns_active_at": null,
    "conns_inactive_at": "2025-02-18T22:41:43.534395Z",
    "tun_type": "cfd_tunnel",
    "metadata": {},
    "status": "inactive",
    "remote_config": true,
    "credentials_file": {
      "AccountTag": "699d98642c564d2e855e9661899b7252",
      "TunnelID": "c1744f8b-faa1-48a4-9e5c-02ac921467fa",
      "TunnelName": "api-tunnel",
      "TunnelSecret": "bTSquyUGwLQjYJn8cI8S1h6M6wUc2ajIeT7JotlxI7TqNqdKFhuQwX3O8irSnb=="
    },
    "token": "eyJhIjoiNWFiNGU5Z..."
  }
}
```

Copy the `id` and `token` values shown in the output. You will need these values to configure and run the tunnel.

The next steps depend on whether you want to [publish an application to the Internet](#3a-publish-an-application) or [connect a private network](#3b-connect-a-network).

## 3a. Publish an application

Before you publish an application through your tunnel, you must:

* [Add a website to Cloudflare](https://developers.cloudflare.com/fundamentals/manage-domains/add-site/).
* [Change your domain nameservers to Cloudflare](https://developers.cloudflare.com/dns/zone-setups/full-setup/setup/).

Follow these steps to publish an application to the Internet. If you are looking to connect a private resource, skip to the [Connect a network](#3b-connect-a-network) section.

1. Make a [`PUT` request](https://developers.cloudflare.com/api/resources/zero_trust/subresources/tunnels/subresources/cloudflared/subresources/configurations/methods/update/) to route your [local service URL](https://developers.cloudflare.com/cloudflare-one/networks/connectors/cloudflare-tunnel/routing-to-tunnel/protocols/) to a public hostname. For example,

   Required API token permissions

   At least one of the following [token permissions](https://developers.cloudflare.com/fundamentals/api/reference/permissions/) is required:

   * `Cloudflare One Connectors Write`
   * `Cloudflare One Connector: cloudflared Write`
   * `Cloudflare Tunnel Write`

   ```bash
   curl "https://api.cloudflare.com/client/v4/accounts/$ACCOUNT_ID/cfd_tunnel/$TUNNEL_ID/configurations" \
     --request PUT \
     --header "Authorization: Bearer $CLOUDFLARE_API_TOKEN" \
     --json '{
       "config": {
           "ingress": [
               {
                   "hostname": "app.example.com",
                   "service": "http://localhost:8001",
                   "originRequest": {}
               },
               {
                   "service": "http_status:404"
               }
           ]
       }
     }'
   ```

   Note

   If you add a multi-level subdomain (more than one level of subdomain), you must [order an Advanced Certificate for the hostname](https://developers.cloudflare.com/cloudflare-one/faq/troubleshooting/#i-see-this-site-cant-provide-a-secure-connection).

   Your ingress rules must include a catch-all rule at the end. In this example, `cloudflared` will respond with a 404 status code when the request does not match any of the previous hostnames.

2. [Create a DNS record](https://developers.cloudflare.com/api/resources/dns/subresources/records/methods/create/) for your application:

   Required API token permissions

   At least one of the following [token permissions](https://developers.cloudflare.com/fundamentals/api/reference/permissions/) is required:

   * `DNS Write`

   ```bash
   curl "https://api.cloudflare.com/client/v4/zones/$ZONE_ID/dns_records" \
     --request POST \
     --header "Authorization: Bearer $CLOUDFLARE_API_TOKEN" \
     --json '{
       "type": "CNAME",
       "proxied": true,
       "name": "app.example.com",
       "content": "c1744f8b-faa1-48a4-9e5c-02ac921467fa.cfargotunnel.com"
     }'
   ```

   This DNS record allows Cloudflare to proxy `app.example.com` traffic to your Cloudflare Tunnel (`<tunnel-id>.cfargotunnel.com`).

This application will be publicly available on the Internet once you [run the tunnel](#4-install-and-run-the-tunnel). To allow or block specific users, [create an Access application](https://developers.cloudflare.com/cloudflare-one/access-controls/applications/http-apps/self-hosted-public-app/).

## 3b. Connect a network

To connect a private network through your tunnel, [add a tunnel route](https://developers.cloudflare.com/api/resources/zero_trust/subresources/networks/subresources/routes/methods/create/):

Required API token permissions

At least one of the following [token permissions](https://developers.cloudflare.com/fundamentals/api/reference/permissions/) is required:

* `Cloudflare One Networks Write`
* `Cloudflare Tunnel Write`

```bash
curl "https://api.cloudflare.com/client/v4/accounts/$ACCOUNT_ID/teamnet/routes" \
  --request POST \
  --header "Authorization: Bearer $CLOUDFLARE_API_TOKEN" \
  --json '{
    "network": "172.16.0.0/16",
    "tunnel_id": "c1744f8b-faa1-48a4-9e5c-02ac921467fa",
    "comment": "Example private network route"
  }'
```

`cloudflared` can now route traffic to these destination IPs. To configure Zero Trust policies and connect as a user, refer to [Connect private networks](https://developers.cloudflare.com/cloudflare-one/networks/connectors/cloudflare-tunnel/private-net/cloudflared/).

## 4. Install and run the tunnel

Install `cloudflared` on your server and run the tunnel using the `token` value obtained in [2. Create a tunnel](#2-create-a-tunnel). You can also get the tunnel token using the [Cloudflare Tunnel token](https://developers.cloudflare.com/api/resources/zero_trust/subresources/tunnels/subresources/cloudflared/subresources/token/methods/get/) endpoint.

* Linux

  1. [Download and install](https://pkg.cloudflare.com/index.html) `cloudflared`.

  2. Run the following command:

     ```sh
     sudo cloudflared service install <TUNNEL_TOKEN>
     ```

* Windows

  1. [Download and install](https://developers.cloudflare.com/cloudflare-one/networks/connectors/cloudflare-tunnel/downloads/#windows) `cloudflared`.

  2. Open Command Prompt as administrator.

  3. Run the following command:

     ```txt
     cloudflared.exe service install <TUNNEL_TOKEN>
     ```

* macOS

  1. [Download and install](https://developers.cloudflare.com/cloudflare-one/networks/connectors/cloudflare-tunnel/downloads/#macos) `cloudflared`.

  2. Open a terminal window and run the following command:

     ```sh
     sudo cloudflared service install <TUNNEL_TOKEN>
     ```

* Docker

  1. Open a terminal window.

  2. Run the following command:

     ```sh
     docker run cloudflare/cloudflared:latest tunnel --no-autoupdate run --token <TUNNEL_TOKEN>
     ```

## 5. Verify tunnel status

To check if the tunnel is serving traffic:

Required API token permissions

At least one of the following [token permissions](https://developers.cloudflare.com/fundamentals/api/reference/permissions/) is required:

* `Cloudflare One Connectors Write`
* `Cloudflare One Connectors Read`
* `Cloudflare One Connector: cloudflared Write`
* `Cloudflare One Connector: cloudflared Read`
* `Cloudflare Tunnel Write`
* `Cloudflare Tunnel Read`

    "tun_type": "cfd_tunnel",
    "metadata": {},
    "status": "healthy",
    "remote_config": true
  }
}
```

A healthy tunnel will have four connections to Cloudflare's network.
