The Tailscale API documentation has moved to https://tailscale.com/api

Device

A Tailscale device (sometimes referred to as node or machine), is any computer or mobile device that joins a tailnet.

Each device has a unique ID (nodeId in the JSON below) that is used to identify the device in API calls. This ID can be found by going to the Machines page in the admin console, selecting the relevant device, then finding the ID in the Machine Details section. You can also list all devices in the tailnet to get their nodeId values.

(A device's numeric id value can also be used in API calls, but nodeId is preferred.)

Device

Subnet routes

Devices within a tailnet can be set up as subnet routers. A subnet router acts as a gateway, relaying traffic from your Tailscale network onto your physical subnet. Setting up subnet routers exposes routes to other devices in the tailnet. Learn more about subnet routers.

A device can act as a subnet router if its subnet routes are both advertised and enabled. This is a two-step process, but the steps can occur in any order:

  • The device that intends to act as a subnet router exposes its routes by advertising them. This is done in the Tailscale command-line interface.
  • The tailnet admin must approve the routes by enabling them. This is done in the Machines page of the Tailscale admin console or via the API.

If a device has advertised routes, they are not exposed to traffic until they are enabled by the tailnet admin. Conversely, if a tailnet admin pre-approves certain routes by enabling them, they are not available for routing until the device in question has advertised them.

The API exposes two methods for dealing with subnet routes:

Get device

GET /api/v2/device/{deviceid}

Retrieve the details for the specified device. This returns a JSON device object listing device attributes.

Parameters

deviceid (required in URL path)

The ID of the device.

fields (optional in query string)

Controls whether the response returns all object fields or only a predefined subset of fields. Currently, there are two supported options:

  • all: return all object fields in the response
  • default: return all object fields except:
    • enabledRoutes
    • advertisedRoutes
    • clientConnectivity (which contains the following fields: mappingVariesByDestIP, derp, endpoints, latency, and clientSupports)
    • postureIdentity

Request example

curl "https://api.tailscale.com/api/v2/device/12345?fields=all" \
  -u "tskey-api-xxxxx:"

Response

{
  "addresses":[
    "100.71.74.78",
    "fd7a:115c:a1e0:ac82:4843:ca90:697d:c36e"
  ],
  "id":"12345",

  // Additional fields as documented in device "Attributes" section above
}
{
  "addresses":[
    "100.74.66.78",
    "fd7a:115c:a1e0:ac82:4843:ca90:697d:c36f"
  ],
  "id":"67890",

  // Additional fields as documented in device "Attributes" section above
}

Delete device

DELETE /api/v2/device/{deviceID}

Deletes the supplied device from its tailnet. The device must belong to the user's tailnet. Deleting shared/external devices is not supported.

Parameters

deviceid (required in URL path)

The ID of the device.

Request example

curl -X DELETE 'https://api.tailscale.com/api/v2/device/12345' \
  -u "tskey-api-xxxxx:"

Response

If successful, the response should be empty:

HTTP/1.1 200 OK

If the device is not owned by your tailnet:

HTTP/1.1 501 Not Implemented
...
{"message":"cannot delete devices outside of your tailnet"}

Expire a device's key

POST /api/v2/device/{deviceID}/expire

Mark a device's node key as expired. This will require the device to re-authenticate in order to connect to the tailnet. The device must belong to the requesting user's tailnet.

Parameters

deviceid (required in URL path)

The ID of the device.

Request example

curl -X POST 'https://api.tailscale.com/api/v2/device/12345/expire' \
  -u "tskey-api-xxxxx:" \
  -H "Content-Type: application/json"

Response

If successful, the response should be empty:

HTTP/1.1 200 OK

Routes

Get device routes

GET /api/v2/device/{deviceID}/routes

Retrieve the list of subnet routes that a device is advertising, as well as those that are enabled for it:

  • Enabled routes: The subnet routes for this device that have been approved by the tailnet admin.
  • Advertised routes: The subnets this device intends to expose.

Parameters

deviceid (required in URL path)

The ID of the device.

Request example

curl "https://api.tailscale.com/api/v2/device/11055/routes" \
-u "tskey-api-xxxxx:"

Response

Returns the enabled and advertised subnet routes for a device.

{
  "advertisedRoutes": ["10.0.0.0/16", "192.168.1.0/24"],
  "enabledRoutes": []
}

Set device routes

POST /api/v2/device/{deviceID}/routes

Sets a device's enabled subnet routes by replacing the existing list of subnet routes with the supplied parameters. Advertised routes cannot be set through the API, since they must be set directly on the device.

Parameters

deviceid (required in URL path)

The ID of the device.

routes (required in POST body)

The new list of enabled subnet routes.

{
  "routes": ["10.0.0.0/16", "192.168.1.0/24"]
}

Request example

curl "https://api.tailscale.com/api/v2/device/11055/routes" \
-u "tskey-api-xxxxx:" \
-H "Content-Type: application/json" \
--data-binary '{"routes": ["10.0.0.0/16", "192.168.1.0/24"]}'

Response

Returns the enabled and advertised subnet routes for a device.

{
  "advertisedRoutes": ["10.0.0.0/16", "192.168.1.0/24"],
  "enabledRoutes": ["10.0.0.0/16", "192.168.1.0/24"]
}

Authorize

Authorize device

POST /api/v2/device/{deviceID}/authorized

Authorize a device. This call marks a device as authorized or revokes its authorization for tailnets where device authorization is required, according to the authorized field in the payload.

This returns a successful 2xx response with an empty JSON object in the response body.

Parameters

deviceid (required in URL path)

The ID of the device.

authorized (required in POST body)

Specify whether the device is authorized. False to deauthorize an authorized device, and true to authorize a new device or to re-authorize a previously deauthorized device.

{
  "authorized": true
}

Request example

curl "https://api.tailscale.com/api/v2/device/11055/authorized" \
-u "tskey-api-xxxxx:" \
-H "Content-Type: application/json" \
--data-binary '{"authorized": true}'

Response

The response is 2xx on success. The response body is currently an empty JSON object.

Tags

Update device tags

POST /api/v2/device/{deviceID}/tags

Update the tags set on a device. Tags let you assign an identity to a device that is separate from human users, and use that identity as part of an ACL to restrict access. Tags are similar to role accounts, but more flexible.

Tags are created in the tailnet policy file by defining the tag and an owner of the tag. Once a device is tagged, the tag is the owner of that device. A single node can have multiple tags assigned.

Consult the policy file for your tailnet in the admin console for the list of tags that have been created for your tailnet. Learn more about tags.

This returns a 2xx code if successful, with an empty JSON object in the response body.

Parameters

deviceid (required in URL path)

The ID of the device.

tags (required in POST body)

The new list of tags for the device.

{
  "tags": ["tag:foo", "tag:bar"]
}

Request example

curl "https://api.tailscale.com/api/v2/device/11055/tags" \
-u "tskey-api-xxxxx:" \
-H "Content-Type: application/json" \
--data-binary '{"tags": ["tag:foo", "tag:bar"]}'

Response

The response is 2xx on success. The response body is currently an empty JSON object.

If the tags supplied in the POST call do not exist in the tailnet policy file, the response is '400 Bad Request':

{
  "message": "requested tags [tag:madeup tag:wrongexample] are invalid or not permitted"
}

Keys

Update device key

POST /api/v2/device/{deviceID}/key

Update properties of the device key.

Parameters

deviceid (required in URL path)

The ID of the device.

keyExpiryDisabled (optional in POST body)

Disable or enable the expiry of the device's node key.

When a device is added to a tailnet, its key expiry is set according to the tailnet's key expiry setting. If the key is not refreshed and expires, the device can no longer communicate with other devices in the tailnet.

Set "keyExpiryDisabled": true to disable key expiry for the device and allow it to rejoin the tailnet (for example to access an accidentally expired device). You can then call this method again with "keyExpiryDisabled": false to re-enable expiry.

{
  "keyExpiryDisabled": true
}
  • If true, disable the device's key expiry. The original key expiry time is still maintained. Upon re-enabling, the key will expire at that original time.
  • If false, enable the device's key expiry. Sets the key to expire at the original expiry time prior to disabling. The key may already have expired. In that case, the device must be re-authenticated.
  • Empty value will not change the key expiry.

This returns a 2xx code on success, with an empty JSON object in the response body.

Request example

curl "https://api.tailscale.com/api/v2/device/11055/key" \
-u "tskey-api-xxxxx:" \
-H "Content-Type: application/json" \
--data-binary '{"keyExpiryDisabled": true}'

Response

The response is 2xx on success. The response body is currently an empty JSON object.

IP Addresses

Set device IPv4 address

POST /api/v2/device/{deviceID}/ip

Set the Tailscale IPv4 address of the device.

Parameters

deviceid (required in URL path)

The ID of the device.

ipv4 (optional in POST body)

Provide a new IPv4 address for the device.

When a device is added to a tailnet, its Tailscale IPv4 address is set at random either from the CGNAT range, or a subset of the CGNAT range specified by an ip pool. This endpoint can be used to replace the existing IPv4 address with a specific value.

{
  "ipv4": "100.80.0.1"
}

This action will break any existing connections to this machine. You will need to reconnect to this machine using the new IP address. You may also need to flush your DNS cache.

This returns a 2xx code on success, with an empty JSON object in the response body.

Request example

curl "https://api.tailscale.com/api/v2/device/11055/ip" \
-u "tskey-api-xxxxx:" \
-H "Content-Type: application/json" \
--data-binary '{"ipv4": "100.80.0.1"}'

Response

The response is 2xx on success. The response body is currently an empty JSON object.

Device posture attributes

Get device posture attributes

The posture attributes API endpoints can be called with OAuth access tokens with an acl or devices scope, or personal access belonging to user roles Owners, Admins, Network Admins, or IT Admins.

GET /api/v2/device/{deviceID}/attributes

Retrieve all posture attributes for the specified device. This returns a JSON object of all the key-value pairs of posture attributes for the device.

Parameters

deviceID (required in URL path)

The ID of the device to fetch posture attributes for.

Request example

curl "https://api.tailscale.com/api/v2/device/11055/attributes" \
-u "tskey-api-xxxxx:"

Response

The response is 200 on success. The response body is a JSON object containing all the posture attributes assigned to the node. Attribute values can be strings, numbers or booleans.

{
  "attributes": {
    "custom:myScore": 87,
    "custom:diskEncryption": true,
    "custom:myAttribute": "my_value",
    "node:os": "linux",
    "node:osVersion": "5.19.0-42-generic",
    "node:tsReleaseTrack": "stable",
    "node:tsVersion": "1.40.0",
    "node:tsAutoUpdate": false
  }
}

Set custom device posture attributes

POST /api/v2/device/{deviceID}/attributes/{attributeKey}

Create or update a custom posture attribute on the specified device. User-managed attributes must be in the custom namespace, which is indicated by prefixing the attribute key with custom:.

Custom device posture attributes are available for the Personal and Enterprise plans.

Parameters

deviceID (required in URL path)

The ID of the device on which to set the custom posture attribute.

attributeKey (required in URL path)

The name of the posture attribute to set. This must be prefixed with custom:.

Keys have a maximum length of 50 characters including the namespace, and can only contain letters, numbers, underscores, and colon.

Keys are case-sensitive. Keys must be unique, but are checked for uniqueness in a case-insensitive manner. For example, custom:MyAttribute and custom:myattribute cannot both be set within a single tailnet.

All values for a given key need to be of the same type, which is determined when the first value is written for a given key. For example, custom:myattribute cannot have a numeric value (87) for one node and a string value ("78") for another node within the same tailnet.

Posture attribute value (required in POST body)

{
  "value": "foo"
}

A value can be either a string, number or boolean.

A string value can have a maximum length of 50 characters, and can only contain letters, numbers, underscores, and periods.
