# Tailscale API
The Tailscale API is a (mostly) RESTful API. Typically, POST bodies should be JSON encoded and responses will be JSON encoded.
# Authentication
Currently based on {some authentication method}. Visit the [admin panel](https://api.tailscale.com/admin) and navigate to the `Keys` page. Generate an API Key and keep it safe. Provide the key as the user key in basic auth when making calls to Tailscale API endpoints.
# APIs

## Device
<!-- TODO: description about what devices are -->
Each Tailscale-connected device has a globally-unique identifier number which we refer as the "deviceID" or sometimes, just "id".
You can use the deviceID to specify operations on a specific device, like retrieving its subnet routes.
To find the deviceID of a particular device, you can use the ["GET /devices"](#getdevices) API call and generate a list of devices on your network.
Find the device you're looking for and get the "id" field.
This is your deviceID.
<a name=device-get></div>
#### `GET /api/v2/device/:deviceid` - lists the details for a device
Returns the details for the specified device.
Supply the device of interest in the path using its ID.
Use the `fields` query parameter to explicitly indicate which fields are returned.
##### Parameters
##### Query Parameters
`fields` - Controls which fields will be included in the returned response.
Currently, supported options are:
* `all`: returns all fields in the response.
* `default`: return all fields except:
* `enabledRoutes`
* `advertisedRoutes`
* `clientConnectivity` (which contains the following fields: `mappingVariesByDestIP`, `derp`, `endpoints`, `latency`, and `clientSupports`)
Use commas to separate multiple options.
If more than one option is indicated, then the union is used.
For example, for `fields=default,all`, all fields are returned.
If the `fields` parameter is not provided, then the default option is used.
##### Example
```
GET /api/v2/device/12345
curl 'https://api.tailscale.com/api/v2/device/12345?fields=all' \
-u "tskey-yourapikey123:"

<a name=device-delete></div>
#### `DELETE /api/v2/device/:deviceID` - deletes the device from its tailnet
Deletes the provided device from its tailnet.
The device must belong to the user's tailnet.
Deleting shared/external devices is not supported.
Supply the device of interest in the path using its ID.
##### Parameters
No parameters.
##### Example
```
DELETE /api/v2/device/12345
curl -X DELETE 'https://api.tailscale.com/api/v2/device/12345' \
-u "tskey-yourapikey123:" -v
```
Response
If successful, the response should be empty:
```
< HTTP/1.1 200 OK
...
* Connection #0 to host left intact
* Closing connection 0
```
If the device is not owned by your tailnet:
```
< HTTP/1.1 501 Not Implemented
...
{"message":"cannot delete devices outside of your tailnet"}
```
<a name=device-routes-get></div>
#### `GET /api/v2/device/:deviceID/routes` - fetch subnet routes that are advertised and enabled for a device
Retrieves the list of subnet routes that a device is advertising, as well as those that are enabled for it. Enabled routes are not necessarily advertised (e.g. for pre-enabling), and likewise, advertised routes are not necessarily enabled.
##### Parameters
No parameters.
##### Example
```
curl 'https://api.tailscale.com/api/v2/device/11055/routes' \
-u "tskey-yourapikey123:"
```
Response
```
{
"advertisedRoutes" : [
"10.0.1.0/24",
"1.2.0.0/16",
"2.0.0.0/24"
],
"enabledRoutes" : []
}
```
<a name=device-routes-post></div>
#### `POST /api/v2/device/:deviceID/routes` - set the subnet routes that are enabled for a device
Sets which subnet routes are enabled to be routed by a device by replacing the existing list of subnet routes with the supplied parameters. Routes can be enabled without a device advertising them (e.g. for preauth). Returns a list of enabled subnet routes and a list of advertised subnet routes for a device.
##### Parameters
###### POST Body
`routes` - The new list of enabled subnet routes in JSON.
```
{
"routes": ["10.0.1.0/24", "1.2.0.0/16", "2.0.0.0/24"]
}
```
##### Example
```
curl 'https://api.tailscale.com/api/v2/device/11055/routes' \
-u "tskey-yourapikey123:" \
--data-binary '{"routes": ["10.0.1.0/24", "1.2.0.0/16", "2.0.0.0/24"]}'
```
Response
```
{
"advertisedRoutes" : [
"10.0.1.0/24",
"1.2.0.0/16",
"2.0.0.0/24"
],
"enabledRoutes" : [
"10.0.1.0/24",
"1.2.0.0/16",
"2.0.0.0/24"
]
}
```
## Tailnet
A tailnet is the name of your Tailscale network.
You can find it in the top left corner of the [Admin Panel](https://login.tailscale.com/admin) beside the Tailscale logo.
`alice@example.com` belongs to the `example.com` tailnet and would use the following format for API calls:
```
GET /api/v2/tailnet/example.com/...
curl https://api.tailscale.com/api/v2/tailnet/example.com/...
```
For solo plans, the tailnet is the email you signed up with.
So `alice@gmail.com` has the tailnet `alice@gmail.com` since `@gmail.com` is a shared email host.
Her API calls would have the following format:
```
GET /api/v2/tailnet/alice@gmail.com/...
curl https://api.tailscale.com/api/v2/tailnet/alice@gmail.com/...
```
Tailnets are a top-level resource. ACL is an example of a resource that is tied to a top-level tailnet.

### ACL
<a name=tailnet-acl-get></a>
#### `GET /api/v2/tailnet/:tailnet/acl` - fetch ACL for a tailnet
Retrieves the ACL that is currently set for the given tailnet. Supply the tailnet of interest in the path. This endpoint can send back either the HuJSON of the ACL or a parsed JSON, depending on the `Accept` header.
##### Parameters
###### Headers
`Accept` - Response is parsed `JSON` if `application/json` is explicitly named, otherwise HuJSON will be returned.
##### Returns
Returns the ACL HuJSON by default. Returns a parsed JSON of the ACL (sans comments) if the `Accept` type is explicitly set to `application/json`. An `ETag` header is also sent in the response, which can be optionally used in POST requests to avoid missed updates.
<!-- TODO (chungdaniel): define error types and a set of docs for them -->
##### Example
###### Requesting a HuJSON response:
```
GET /api/v2/tailnet/example.com/acl
curl 'https://api.tailscale.com/api/v2/tailnet/example.com/acl' \
-u "tskey-yourapikey123:" \

<a name=tailnet-acl-post></a>
#### `POST /api/v2/tailnet/:tailnet/acl` - set ACL for a tailnet
Sets the ACL for the given tailnet. HuJSON and JSON are both accepted inputs. An `If-Match` header can be set to avoid missed updates.
Returns error for invalid ACLs.
Returns error if using an `If-Match` header and the ETag does not match.
##### Parameters
###### Headers
`If-Match` - A request header. Set this value to the ETag header provided in an `ACL GET` request to avoid missed updates.
`Accept` - Sets the return type of the updated ACL. Response is parsed `JSON` if `application/json` is explicitly named, otherwise HuJSON will be returned.

Replaces the list of DNS nameservers for the given tailnet with the list supplied by the user.
Supply the tailnet of interest in the path.
Note that changing the list of DNS nameservers may also affect the status of MagicDNS (if MagicDNS is on).
##### Parameters
###### POST Body
`dns` - The new list of DNS nameservers in JSON.
```
{
"dns":["8.8.8.8"]
}
```
##### Returns
Returns the new list of nameservers and the status of MagicDNS.
If all nameservers have been removed, MagicDNS will be automatically disabled (until explicitly turned back on by the user).
##### Example
###### Adding DNS nameservers with the MagicDNS on:

Retrieves the DNS preferences that are currently set for the given tailnet.
Supply the tailnet of interest in the path.
##### Parameters
No parameters.
##### Example
```
GET /api/v2/tailnet/example.com/dns/preferences
curl 'https://api.tailscale.com/api/v2/tailnet/example.com/dns/preferences' \

#### `POST /api/v2/tailnet/:tailnet/dns/preferences` - replaces the DNS preferences for a tailnet
Replaces the DNS preferences for a tailnet, specifically, the MagicDNS setting.
Note that MagicDNS is dependent on DNS servers.
If there is at least one DNS server, then MagicDNS can be enabled.
Otherwise, it returns an error.
Note that removing all nameservers will turn off MagicDNS.
To reenable it, nameservers must be added back, and MagicDNS must be explicitly turned on.
##### Parameters
###### POST Body
The DNS preferences in JSON. Currently, MagicDNS is the only setting available.
`magicDNS` - Automatically registers DNS names for devices in your tailnet.
```
{
"magicDNS": true
}
```

This is a temporary fork of Go 1.13's os/exec package,
to work around https://github.com/golang/go/issues/36644.
The main modification (outside of removing some tests that require
internal-only packages to run) is:
```
commit 3c66be240f1ee1f1b5f03bed79eb0d9f8c08965a
Author: Avery Pennarun <apenwarr@gmail.com>
Date: Sun Jan 19 03:17:30 2020 -0500
Cmd.Wait(): handle EINTR return code from os.Process.Wait().
This is probably not actually the correct fix; most likely
os.Process.Wait() itself should be fixed to retry on EINTR so that it
never leaks out of that function. But if we're going to patch a
particular module, it's safer to patch a higher-level one like os/exec
rather than the os module itself.
