Is it possible to add IP addresses to firewall groups using the API? I have a group of IP addresses which are blocked from my network. I would like to be able to add addresses to this group automatically based on log files my servers generate throughout the day.

We have been contracted with building a Guest Portal for a clients Unifi. The portal we have built runs on the "remote server" setting (but the remote server is a local address on the same computer as the AP) and uses a standard web (html, css, apache, mysql, php) environment.

This library accesses the AP and authenticates the MAC Address.

The production Unifi runs on a server and there are about 20(ish) locations that connect to the AP. Currently we are only testing the guest portal on a single location, but this gives you an idea of the setup.

Here is how the process is supposed to go:

1. We require the customer to enter their email address & accept the terms and conditions
2. There is a PHP script using the Unifi API Client that sends a request to the AP to allow the guest
3. We receive a "success" response from the AP
4. We redirect the customers device to a website
5. They now have full access to the wifi.

This works as-expected, maybe 20-30% of the time, the customer is connected fine.

The other 70-80% of the time, at Step 4, after redirecting, the device just refreshes back to the guest authentication page. This happens even though we always receive a "success" response from the AP when trying to authenticate a customers device.

It appears there may be some sort of delay with the AP registering the guest access. I have noticed even when Unauthenticating a user manually from the server it can take up to a minute before the device is asked to authenticate again (I'm not sure if this is related, but it may be).

We have checked all of the networks, connections, etc. and everything appears to be fine. The code appears to be working as-expected as clients eventually log in fine. The issue appears to be between when the authentication is received by the AP and when it actually takes effect.

Is there something we should be doing with the API to fix this issue?

I was looking for a way to add mac filters via an API and I found this project, but I think there is a bug in Client.php
In function set_wlan_mac_filter there is following if statement:
if (in_array($mac_filter_policy, ['allow', 'deny'])) return false;
Shouldn't it be:
if (!in_array($mac_filter_policy, ['allow', 'deny'])) return false;

Otherwise it would return false everytime I give a legit MAC policy.

Good afternoon,

Basically this is just a question with the usage of your API.
I use the API for some simple scripting to get some numbers out of the system,
off line devices etc.
I spend quite some time lately adding all devices to an Scheduled Upgrade schema,
but with the change of devices / sites maybe some AP's / switches are not in the upgrade any more.

Is there a way with the API to get 'some' info regarding the scheduled upgrades?
I searched through the 'Client.php' but was not able to find anything,
the API page https://ubntwiki.com/products/software/unifi-controller/api also didnt note anything.
Also didn't find any info in the response (json) per device, or maybe i overlooked..

Hope you have some info.

Hi,

I get only data with list_sites(), but if I try other functions it returns "false"...?

Hi,

I have cloned the UniFi-API-client repository, loaded its libraries with composer and filled out the config appropriately with the correct username, password, https://...:8443, and my controller version.

I then created a new file 'login.php':

require_once("vendor\autoload.php");
require_once('config.php');
$unifi_connection = new UniFi_API\Client($controlleruser, $controllerpassword, $controllerurl, $site_id, $controllerversion);
$set_debug_mode = $unifi_connection->set_debug($debug);
$loginresults = $unifi_connection->login();

I do not get any errors on loading:
require_once("vendor\autoload.php");
require_once('config.php');

Contents of config.php:

$controlleruser = 'admin'; // the user name for access to the UniFi Controller
$controllerpassword = '*****'; // the password for access to the UniFi Controller
$controllerurl = 'https://...:8443'; // full url to the UniFi Controller, eg. 'https://22.22.11.11:8443'
$controllerversion = '5.10.23'; // the version of the Controller software, eg. '4.6.6' (must be at least 4.0.0)
$debug = false;

The login function simply returns "false", so it is not getting the $_SESSION['unificookie'] value.

I checked all of the settings on my controller's UI, and I did not find anything I needed to enable to allow calls like this.

Do you know of anything in the Controller UI that might fix this problem?

Maybe my client.php's config values?

client.php config values:

protected $baseurl            = 'https://127.0.0.1:8443';
protected $user               = 'admin';
protected $password           = '************';
protected $site               = 'https://*.*.*.*:8443';
protected $version            = '5.10.23';

Should the $baseurl be something other than my local host?

I appreciate any and all help!

Thank you,

Jack

Is there any way to get the controller version & update controller itself with this API?

I have found it's possible to grab a list of port forwardings, but is it possible to enable/disable a port forwarding rule using the API?

Calling list_clients() returns information about: signal, rssi, noise, etc... I'm trying to coordinate the dBm levels I see in the Unifi controller UI with what shows up via the API.

I have a client in the Unifi Controller which shows: "99% (-43 dBm)" but what comes back via list_clients() and the API is:

Is there a calculation I need to run to get the actual dBm?

Hello!

Would it be possible to change the hostname of an authorized (to be able to see it in the controller) device with the API?

Thanks!

please add the following two scripts to your examples, I execute them from the commandline on windows via batch files so the scripts do not output json format.

When pulling /stat/dpi a list of applications and the relevant data usage is returned. The application and the category they belong to are only identified by a number. Is there a comprehensive list that exists to identify the app/category id to a name?

Would love to be able to pull the statuscake server list and add that to a firewall group so I could block all other ping responses (as an example).

Can somebody share a simple PHP code of a website used in /guest/s/default to auth clients when they request to access a free open network managed with an external portal in Ubiquiti?
I looked through this repository but I found a guest auth.php but the mac address has to be inserted manually and so I wasn't able to use it for my purpose (Auth guests with a website when they access a network - External Captive Portal).
Thank you, waiting for an answer

UNIFI Controller has capability to chedule a speedtest for checking connectity of the provider.
Is there a way to retrieve the result of last speedtest via this API?

Thanks

Title says it all: I'd like to be able to enable or disable an SSID (in my case the guest WiFi) via API call.
Reasoning: As a next step I'd like to toggle the guest WiFi from OpenHab (perhaps at some time with Alexa integration) using Art-of-WiFi.

I would like to find a way to fix ips to devices, which can be done through the UI (UniFi->Clients->click on client->Configuration->Network):


I've been trying to discover the api by myself, in order to make a PUT request into a client and change that field to TRUE.
Listing all clients a "use_fixedip" boolean fields appears:

Also, a fixed_ip field:

Is there anyway to actually set the value of that field?

Thank you.

Any chances of working out an api call for updating a port forwarding destination? For me personally, it would help in fixing a failover from one machine to another thats exposed via port forwarding.

Hi,

This is a great piece of work.

I have put together a python based network display. I was having a hard time finding the new URL's for the UDM Pro (which you have!). I'm actually using the websocket connection to get events and display them.

Right now I just use a flag to set whether this is a Unifi OS device or not manually. I see that you can detect it automatically.

This is the code you use:

        /**
         * check whether we have a "regular" controller or one based on UniFi OS
         */
        if (!($ch = $this->get_curl_resource())) {
            trigger_error('$ch as returned by get_curl_resource() is not a resource');
        } else {
            curl_setopt($ch, CURLOPT_HEADER, true);
            curl_setopt($ch, CURLOPT_POST, true);
            curl_setopt($ch, CURLOPT_NOBODY, true);
            curl_setopt($ch, CURLOPT_URL, $this->baseurl . '/');

            /**
             * execute the cURL request and get the HTTP response code
             */
            curl_exec($ch);
            $http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);

            if (curl_errno($ch)) {
                trigger_error('cURL error: ' . curl_error($ch));
            }

            if ($http_code === 200) {
                $this->is_unifi_os = true;
            }

Can you explain how this works? I have read it, but I'm not sure how to determine if it's a Unifi OS response (200 is obvious enough) but the baseurl just seems to be the regular access url.

Or is it just accessing the regular 8443 port, and if that fails assuming it's a Unifi OS device?

Thanks.

I'm creating a new voucher using create_voucher and the response only contains the creation date but no voucher code.

Can there be a function added to enable/disable/toggle POE setup on a port. My use case is to restart the connected POE-Device and to add a timed on/off for power savings.

Hello!

I'm learning to use Laravel and I would like to implement the API with laravel.
I followed the installation instructions with composer but I have not managed to make it work.
Do you have to do some additional step to the one indicated in the installation steps?

Greetings and thanks!

Sorry for my english.

I'm using locate_ap() and power_cycle_switch_port() and I keep getting api.err.UnknownDevice, it doesn't seem to understand the MAC I'm giving it. I'm using the same format with colon separation, and I'm using the only logical MAC for the switch. Any ideas?

UniFi 5.6.16

We have a script set up to automatically adopt and configure ap's. Currently the set_wlan_group function is not operating correctly and the wlan group remains on default. tested multiple ap's with multiple wlan groups and device ids and no change.

I have what I think may be a unique problem... We're an ISP that provides Unifi WiFi to our members. Each member has their own site in our controller, so we have a rather large controller. Our controller has just about 3000 sites on it.

list_sites() only returns the first 2997 sites no matter how many sites are actually on the controller. I've tested it by adding 50 sites at a time, as soon as the total is above 2997 it stops returning all the sites. My guess is that the Unifi controller limits how many sites it returns via that API call? Do you know any way to work around this limitation?

We're currently running 5.12.35 of the Unifi controller software.

Hi

Can someone explain, how the mapping works?
I found my rule.xml and my categories is:

        <app_categories>
                <app_category id="128" name="Instant messengers" />
                <app_category id="129" name="Peer-to-peer networks" />
                <app_category id="131" name="File sharing services and tools" />
                <app_category id="132" name="Media streaming services" />
           ...

And an example, twitch from same file:

<application cat_id="132" app_id="19" name="Twitch.tv" />

BUT, the category indexes from the api is different:

                            [app] => 19
                            [cat] => 4

But cat should ( in my mind ) be 132.

Any ideas?

Controller version: 5.10.25

I want this so I can override it with my own options for curl i.e. Extend the timeout

Hello.
Please tell me, how can i check device is blocked or not by API?
I see only block_sta() and unblock_sta().
I looked at the methods list_devices('MAC') and list_guests(), but there also I did not find anything.
In admin area there are difference between blocked and not blocked devices.
Thank you!

Hi,

When I want to make a request like ($results = $unifi_connection->list_admins();) then the XAMPP ports keep changing and my website keeps loading and finally crashes...
Do you know how to fix it or do you have an idea where the problem lies?

Thanks in advance.

Hi,

I'm trying to use the set_ap_radiosettings command to change the AP channel, but it doesn't seam to work with my controller version (5.5.24): it answer me back invalidPayload

I've tried to see the what does the controller call, and I've noticed two difference:

• There's some field missing (antenna_gain,min_rssi_enabled,min_rssi,hard_noise_floor_enabled)
• If the AP have the 5ghz, it pass all the two radio configuration together, otherwise it answer ok, but it doesn't really apply the config to the AP

Also would be useful to have a function that read the current ap settings and only modify the one you need to touch, passing the complete setting back to the controller.

Hello, i have sucessfully added scheduled task that enables and disables certain wlan network, using disable_wlan function, only issue is that when this funtion is called, controller disables all wlans for brief period and then enables them again, thus disconnecting client that are conected to those networks. Controller version is: 5.4.14.

Don't know if this would be useful here but, I made a website for our University so that people could register their MAC addresses to the UniFi Controller.

Any idea , if I can login using http only?
When visiting on browser , i cant access http

I'm using the client to pull the download data of a given device, and I must be missing something very simple. The goal will be "run once daily, check amount, and if amount > 100MB then do X".

Using stat_daily_user, and the following very simple code, the data seems to not match the Controller report (5.9.29, with a USG3). 5 minute data is set to 1 day retention. I did change the function to be 24 hours instead of 12 but I was seeing the same thing before. I'm rusty at PHP so I could be making a bonehead mistake. :) I did check the MAC was the right one, twice. I've replaced the actual MAC with secret_mac_here.

// ... sample code from list_user example
$result           = $unifi_connection->stat_daily_user("secret_mac_here");
// ...
for ($i=0; $i < count($result); ++$i) {
        // to_local_time($result[$i]->time);       
        $rx_bytes=$rx_bytes + $result[$i]->rx_bytes;
        echo (($result[$i]->rx_bytes)/1024) . "\n";
           //  echo $result->data->oid . "\n";
}
echo "Total kbytes rcvd " . ($rx_bytes/1024) . "\n";

returns

2222.9465717516
3717.4771168644
7594.3761160714
2127.058656754
9998.3134135585
8743.44921875
1332.3310546875
Total kbytes rcvd 35735.952148438

I read that as "35MB". The controller shows:

which is obviously quite different.

Am I missing a conversion somewhere or completely misunderstanding how the controller renders things, or any number of other newbie issues?

Thanks! This was unbelievably easy to get started with. Also having problems with understanding the conversion of the time but that's another story and quite less important I think.

Good Day, here's the situation:
For instance, I have a guest that is already connected to an AP, and I want to extend his/her connection. How do I do that?

I've seen this function:

public function extend_guest_validity($guest_id)
 {
     if (!$this->is_loggedin) {
         return false;
     }

     $payload  = ['_id' => $guest_id, 'cmd' => 'extend'];
     $response = $this->exec_curl('/api/s/' . $this->site . '/cmd/hotspot', $payload);

     return $this->process_response_boolean($response);
 }

How Will I use it to extend the connection with a specific time?

Hi,
I hope you can help me out.

Im trying to figure out a way to pull the USG logs from firewall... Prefferrably real time...
same command as the SSH command "tail -f /var/log/messages"

I need to be able to import it to a database and make some queries to it, so I can dynamically update my firewall rules... I have a way to dynamically update the firewall rules, but im having a hard time pulling the logs from the USG

Does your api class support this ? err....: pull the /var/log/messages from USG

I've got a new UDM Pro and was looking for a way to enable/disable my kid's gaming systems so they don't overuse them. I found your scripts and they will definitely do the job if I can sole one thing.

Currently, they do block and unblock as expected, but neither script ends unless you hit ctrl-c.

I'm not a strong programmer but I've tried adding an exit after the for loop but that doesn't seem to work.

Any ideas?

Finally got a chance to put this to the test, and for some reason it ended up downgrading the firmware, even though it was already on the latest, since it must have just seen that there was a different version available and ran with that.

I'm hoping there are separate API calls for upgrade/downgrade to prevent this from happening? The frustrating thing is that I can't seem to get it to find the latest firmware again, so I'll have to reinstall that manually. I'll also see if anyone has any suggestions on the Ubiquiti forums.

Why for internal errors use trigger_error() instead of trow()?
Only in _constructor() - trigger_error() is on it's place.
Using of trigger_error don't allow to use 'try catch', instead you must use set_error_handler().
When remote host is not available - it's not a error, it is a 'exception'.

I am trying to change the "Guest Password" in my controller.
I can connect to it with $unifi_connection->list_settings(); no problem and get an output of all the settings.
But when I try $unifi_connection->set_guestlogin_settings() I get no response and no change in the controller
I get the [site_id] => xxxxxxxxxxxxxxxxxx from the output of list_settings(). Is this right?

Any help is greatly appreciated. Thanks

`<?PHP
require_once('Client.php');

require_once('config.php');

$unifi_connection = new UniFi_API\Client($controlleruser, $controllerpassword, $controllerurl, $siteid, $controllerversion, false);

$login = $unifi_connection->login();

$results = $unifi_connection->list_settings();

$change = $unifi_connection->set_guestlogin_settings(true,true,true,'https://www.google.ca','aaaaa','24','h','xxxxxxxxxxxxxxx');

echo $change;`

Hi, thank you for providing this API it's very useful. I have a problem retrieving the necessary fields of the device object though. When I use the list_devices method, it lists the devices but without the "name" field. Could you add the "name" field (and possibly other missing fields) in the response ? Or maybe should I retrieve this field by some other mean ?

Cool API library thanks!

Do you have an API call to create a site?

An API call to create a user for a site?

I'm having issues with stat_daily_site, When i pass timestamps to it i do not get a response. Even when copying the same values that is generated inside of the function. Also it is not possible to get the wlan-num_sta values.

I'm not sure if anyone has encountered this yet, I've done a bit of digging but didn't see anything. We are running:

$unifi->authorize_guest( $request_id , 43200 , null , null , null , $request_ap );

I'm expecting this to last 30 days, but the access appears to expire within 24 hours - could something internal in Unifi be overriding this?

Hi,

I am working on unify version 5.5.24 and every time that I try to use methods that use sitemgr url this fails.

I am try to create and delete some test sites and the error is always the same, api.err.NoSiteContext but if i use list_settings on a site the SiteContext works.

But in all the cases curl debug give [http_code] => 401 - UNAUTHORIZED

I tried using the code in localhost and others ways but did not find the issue that I am doing or not.

sitemgr url still its working in 5.5.24?

Best Regards

I was wondering if it is possible to change the password for the guest portal like it is possible to change the WLAN password using the API.

Hello,
I'm trying to handle vouchers using this API and for some reason the revoke_voucher() function doesn't seem to work.
I've created a voucher on the Hotspot Manager page. (65785-57546)

The vouchers are valid and I'm able to get the voucher's details using stat_voucher().

When I do:

var_dump($unifi_connection->revoke_voucher('6578557546'));

it returns true however the voucher is still listed on the Hotspot Manager and I'm able to login to the guest portal using it.

Some debugging I've tried:

• Made sure I was logged in with $unifi_connection->login()
• Passed the voucher code directly from stat_voucher to revoke_voucher().
• Tried with different voucher codes and one-time use & multi-use codes.
• Checked web server error log (no errors found).

Any ideas?
I'm using PHP 7.2.17, downloaded the project via Composer and my UniFi controller is on version 5.10.23 if that's of any help.
//Carl

this is the result of the script that I ran:

[ { "_id": "5d81c805609b0e273c25796e", "site_id": "5d81a22c609b0e1278b62e9a", "create_time": 1568786437, "code": "6386473243", "for_hotspot": false, "admin_name": "admin", "quota": 0, "duration": 2000, "used": 0, "qos_overwrite": false, "note": "sadofnowe:}{:", "status": "VALID_MULTI", "status_expires": 0 } ]

How do I make a custom value/string for "code"

eg. "code":"asodoiw124"
instead of "code": "6386473243"

On my current setup, I was having problems logging in and I've traced the issue to line 151 in Client.php. The line is as follows:

preg_match_all('|Set-Cookie: (.*);|U', substr($content, 0, $header_size), $results);

In my instance, the reponse is all lowecase, so 'Set-Cookie' doesn't match 'set-cookie'

Changing the line to
preg_match_all('|set-cookie: (.*);|u', substr($content, 0, $header_size), $results);
fixed the issue in my case. But can this line to changed to accept any case?

The last seen date & time seems to be different to the controller GUI, it doesn't seem to update?

using $unifi->stat_allusers(24);
