Navigating the configuration of SPS
The main starting point of navigating the SPS configuration using REST is the https:<IP-address-of-SPS>/api/configuration endpoint. If you query this endpoint, the response contains a list of other endpoints that you can follow to list the various resources of SPS, or to list the objects of a specific resource. For example, https:<IP-address-of-SPS>/api/configuration/rdp lists resources related to controlling the Remote Desktop (RDP) protocol, while https:<IP-address-of-SPS>/api/configuration/rdp/channel_policies lists the available RDP Channel Policies.
Note that when you want to create an object that references another object (for example, a Channel Policy that uses a Content Policy), then the referenced object (in this case, the Content Policy) must already exist. For details, see Create a new object.
To modify or delete an object, you need the ID of the object. For details, see Change an object and Delete an object.
The following is a sample command to query the https:<IP-address-of-SPS>/api/configuration endpoint, and a sample response.
curl --cookie cookies https:<IP-address-of-SPS>/api/configuration

Modifying the configuration of SPS
The following sections describe deleting, creating and changing objects.
Delete an object
To delete a configuration object (for example, a policy), use a DELETE request with the ID of the object as the key.
-
You cannot delete policies or objects that are used in other policies (for example, you cannot delete a Time policy that is used in a Channel policy).
-
To delete an element of a list (for example, a user from a local user database), use a PUT request. The body the request should include the entire object, but remove the element you want to delete from the related list of the object.
-
You cannot delete built-in policies that are available on SPS by default.
-
You must commit your changes to take effect. For details, see Commit a transaction.
URL
DELETE https:<IP-address-of-SPS>/api/configuration/<endpoint>/<object-id>
Cookies
| session_id |
Contains the authentication token of the user |
Required |
The value of the session ID cookie received from the REST server in the authentication response, for example, a1f71d030e657634730b9e887cb59a5e56162860. For more information on authentication, see Authenticate to the SPS REST API.
NOTE: This session ID refers to the connection between the REST client and the SPS REST API. It is not related to the sessions that SPS records (and which also have a session ID, but in a different format). |
Sample request
The following command deletes an RDP Channel policy.
curl --cookie cookies -X DELETE -https:<IP-address-of-SPS>/api/configuration/rdp/channel_policies/<object-id>
Response
The following is a sample response received.
{
"meta": {
"first": "/api/configuration/rdp/channel_policies/-20100",
"href": "/api/configuration/rdp/channel_policies/<id-of-the-deleted-object>",
"last": "/api/configuration/rdp/channel_policies/<id-of-the-deleted-object>",
"next": null,
"parent": "/api/configuration/rdp/channel_policies",
"previous": "/api/configuration/rdp/channel_policies/655555",
"transaction": "/api/transaction"
}
}
Status and error codes
The following table lists the typical status and error codes for this request. For a complete list of error codes, see Application level error codes.
| 200 |
OK |
The resource was successfully deleted. |
| 401 |
Unauthenticated |
The requested resource cannot be retrieved because the client is not authenticated and the resource requires authorization to access it. The details section contains the path that was attempted to be accessed, but could not be retrieved. |
| 403 |
Unauthorized |
The requested resource cannot be retrieved because the client is not authorized to access it. The details section contains the path that was attempted to be accessed, but could not be retrieved. |
| 409 |
Conflict |
No open Transaction is available. Open a transaction before using this request. For details, see Open a transaction. |
Create a new object
To create a new object (for example, a new policy), complete the following steps.
-
Authenticate and open a transaction.
-
Post the new object as a JSON object to the appropriate resource URL.
-
If successful, the REST server creates an ID for the new object, and returns it in the key field of the response.
-
Commit the transaction.
Note the following points when you create a request:
-
Note that you cannot simply use the JSON from the response of a similar object. If the object contains references to other resources (for example, a Channel policy references a Time policy), then the JSON object contains an embedded meta object. To get a valid JSON that you can use, you have to replace this embedded object with the ID (key) of the referenced object. For example, the following is a reference to a Time policy:
"time_policy": {
"key": "-100",
"meta": {
"href": "/api/configuration/policies/time_policies/-100"
}
}
In a POST or PUT request, you have to change it to the following:
"time_policy": "-100",
Starting with version 6.1.0, when querying a list of objects, the API response includes the body of the referenced objects as well, not only its reference key, but only if they are immediate child nodes.
-
You have to include empty fields in the object as well, for example:
"users": [
{ "certificates": [], "passwords": [ "<reference-to-password>" ], "public_keys": [], "username": "myusername" }
]
-
The API ignores any unrecognized or nonexistent keys that appear in the body of POST and PUT requests. For example, if you mistype the name of an optional key, it will be silently ignored.
-
The body wrapper that is displayed in the response is not needed when you create or modify an object, for example:
{
"name": "my-local-user-database",
"users": [
{ "certificates": [], "passwords": [ "<reference-to-password>" ], "public_keys": [], "username": "myusername" }
]
}
URL
POST https:<IP-address-of-SPS>/api/configuration/<path-to-the-parent-resource>
Table 1: Headers
| Content-Type |
Specifies the type of the data sent. SPS uses the JSON format |
Required |
application/json |
| session_id |
Contains the authentication token of the user |
Required |
The value of the session ID cookie received from the REST server in the authentication response, for example, a1f71d030e657634730b9e887cb59a5e56162860. For details on authentication, see Authenticate to the SPS REST API. |
Sample request
The following command creates a new RDP Channel policy. The data content of the request is read from the file body.json
curl -H "Content-Type: application/json" -d @body.json --cookie session_id=1aca4793549c6f22aecd98bc1047d1bf32dd76ef -X POST https://<object-id>/api/configuration/rdp/channel_policies/
For a simple RDP Channel policy that uses the default settings and allows only the Drawing channel, the JSON object is the following.
{
"name": "drawing-only",
"rules": [
{
"actions": {
"audit": true,
"content_policy": null,
"four_eyes": false,
"ids": false
},
"allowed_for": {
"clients": [],
"gateway_groups": [],
"remote_groups": [],
"servers": [],
"time_policy": "-100"
},
"channel": "#drawing"
}
]
}
Response
The following is a sample response received, showing the properties of Content policy objects.
