# 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.
|
||||
|
||||
#### `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

#### `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.
|
||||

||||

|
||||
|
||||
|

|
||||
No parameters.
|
||||
|
||||

||||
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"}
|
||||
```
|
||||
|
||||
|
||||
#### `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" : []
|
||||
}
|
||||
```
|
||||
|
||||
#### `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
|
||||
|
||||
#### `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
|

`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.

|
||||
* `default`: return all fields except:
|
||||
* `enabledRoutes`
|
||||
* `advertisedRoutes`

```
|

|
||||
|
||||
Response:
|
||||
|
||||
If there are no DNS servers, it returns an error message:
|
||||
```
|
||||
{
|
||||
"message":"need at least one nameserver to enable MagicDNS"
|
||||
}
|
||||

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:

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.
