This document covers the control panels' APIs. You need to be logged in with the appropriate privileges to call a function.

GET" and "POST" methods are supported.

Authentication methods

Session unique ID authentication

You can use this method when working with a control panel through your web browser.

Follow the link:

The control panel will return either an error message or the following XML document:
<?xml version="1.0" encoding="UTF-8"?>
<auth id="session id"/>

You should specify this session id in the auth parameter to each call to a control panel. The session id is valid for one hour. If you do not send any requests to the control panel during that period, you will have to get authorized again.


authinfo authentication

This method can be used for remote function calls. To call a BILLmanager function, you need to add the authinfo parameter and specify a login and password of the user who will call that functions:


You must send the authinfo parameter with each call to the control panel. Authorization via "authinfo" can be restricted to the "white list" of IP addresses and/or networks. You can configure the "white list" through the "RestrictAuthinfoRange" and "Option RestrictAuthinfo" parameters of the configuration file or through the authorization settings.

Key authentication

Used to implement end-to-end user authorization in the control panel from other provider systems using only the administrator's login or password.

If the client is identified by an external script, such as a billing platform, and you need to redirect it to the control panel, bypassing the authorization step. To do this, the script must generate a secret key (any string, at least 16 characters long).

Command to generate a secret key

pwgen -s 16 1

The key is a random line at least 16 symbols long, such as 1234567890qwertyuiop.

The username is "John".

A server administrator may use any of the above authentication methods and execute the following request:


In case of errors, an error message will return. If not, the user will be redirected to:


Following the above link will authorize the user and delete the key.

  • You may specify the key from any IP address. After the user is granted access to the control panel, this IP address will be associated with the session.
  • The key can be used only once.
  • Access is allowed from any IP address (even from those that are denied to access the panel).

Getting data from URL

To get the desired function and its parameter values, study the URL of the form in the billing platform.

For example, the URL for a specific payment. Go to ClientsClients → select a client → click Payments → select a payment → click Edit. The URL of the payment modification form will look like this:

Payment URL
  • func=payment.edit — function for changing the object, viewing its parameters and creating a new object (payment)
  • plid — client id
  • elid — payment id
  • elname — payment number (payment name)

To get the link in the interface, click the icon next to the title of the section you are in.

Calling function with the privileges of another user

To call an function with the privileges of another user, add su=user_name to the URL. A server administrator can call functions as any user; resellers can do so with the privileges of their user accounts. All other users cannot use this method.

Getting results in native languages

To get function results or error messages in your native language, add the lang=language to request (e.g. lang=en). If you specify a non-existent language, a default language will be used (normally, it is English, en)

Output of function results

Output can be generated in XML, JSON and text format. If you wish to receive output results in a specific format, specify the out=format_name parameter.

The out parameter can have one of the following values:

  • xml — data structures in XML will be generated.
  • devel — similar to XML, but the document will contain data describing the user's interface.
  • text — data structures in the text format will be generated
  • json — data structures in JSON will be generated. More information can be found here.
  • JSONdata — similar to JSON. Only data are described
  • print — html for printing. Can be used only for data lists
  • xxxx — you can create a custom output format if needed

If the out parameter is missing, such data are considered to be used by the browser and are converted into HTML.

Operation confirmation

The "sok=ok" parameter in the request emulates clicking on the action confirmation button (Ok, Apply, Add to Cart, etc.) to submit various forms in the BILLmanager interface. For example, editing a tariff plan.

Sending a request without the "sok=ok" parameter is similar to opening a form. To apply the passed values, add the "sok=ok" parameter to the request.

Not all functions that change something are forms. In such functions, the "sok=ok" parameter may not be used.

In queries that aim to get current values, the "sok=ok" parameter is not used.


To redirect to another form after a request is executed (usually a modifying request that contains sok=ok), add the redirect=startform=some.form parameter to the request, where some.form is the API function of the desired form. For more details see List of API functions.

The value of the startform=some.form parameter must be URL-encoded, i.e. startform%3Dsome.form.

modifying.action — an example of the main function

some.form — an example of the function of the form to which you want to redirect

For primary requests such as func=register (registration) and func=logon (authorization), sok=ok is not used, but redirect will also work. 

Local calls to control panel

For local calls to the control panel, you can use the internal utility mgrctl, which has a number of advantages

  • calls are sent directly to the control panel (they do not depend on the web-server)
  • there is no need to store a password, as authentication is always made with permissions of the user who run the script (if you need to perform operations as another user, use the su parameter described above).
  • has built-in hints to all functions and their parameters relevant to your server

Getting a list of tariffs

Following is an example of how to get a list of tariffs. You can call all other functions in the same manner. This example shows only the local call.

The curl utility

curl -k -s "https://IP-address:1500/billmgr?authinfo=login:password&out=xml&func=pricelist"

The mgrctl utility

/usr/local/mgr5/sbin/mgrctl -m billmgr pricelist


If you are using Perl, install the LWP.library. To work with XML documents, you will need the XML::LibXML library.

#!/usr/bin/perl -w
use CGI::Carp qw(fatalsToBrowser);
print "Content-type: text/html\n\n";
use LWP::UserAgent;
use XML::LibXML;
my $result;
# Create a pseudo-browser that will run as MSIE and send the request
$ua = LWP::UserAgent->new;
$ua->agent("Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)");
my $req = HTTP::Request->new(POST => 'https://IP-address:1500/billmgr');
my $res = $ua->request($req);
# Check results
if ($res->is_success) {
	$result = $res->content;
} else {
	die $res->status_line."\n";
# The $result variable contains either an XML document with the list of tariffs,
# or an error message
my $parser = XML::LibXML->new();
my $doc = $parser->parse_string( $result );
my $root = $doc->documentElement();
# Get the list of tariffs
my @tariffs = ();
for( $root->findnodes( "elem/name" ) ){
	push @tariffs, $_->textContent;
# Display the result
for( sort @tariffs ){
	print $_."<br>\n";


PHP enables to use URL like standard files. The DOM XML library is used to handle XML documents:

   $result = "";
   $fh = fopen( "http://IP-ADDR:1500/billmgr?out=xml&func=pricelist", "r" );
   while( $data = fread( $fh, 4096 ) ){
     $result .= $data;
   fclose( $fh );
   // The $result variable contains either an XML document with tariffs,
   // or an error message
   if( $doc = domxml_open_mem( $result ) ){
      $root = $doc->document_element();
      for( $elem = $root->first_child(); $elem; $elem = $elem->next_sibling() ){
         for( $node = $elem->first_child(); $node; $node = $node->next_sibling() ){
            if( $node->node_name() == "name" ){
               echo $node->get_content();
               echo "\n";



You should use the urllib2 library. Use the xml.dom.minidom library for working with XML documents.

#!/usr/bin/env python
# -*- coding: utf-8 -*-

from urllib2 import urlopen
from xml.dom import minidom

print "Content-type: text/html\n\n"
res = urlopen('http://IP-ADDR:1500/billmgr?func=pricelist&out=xml')

# The res variable contains either the XML document with the list of tariffs,
# or an error message

xmldoc = minidom.parse(res)

# Get the list of tariffs and display its result

for node in xmldoc.getElementsByTagName('elem'):
for name in node.getElementsByTagName('name'):
print ('%s<br>' % name.firstChild.nodeValue)

Format of requests and results

Requests are described as follows:

Function: a function name to be passed in the func parameter.

Parameters: a list of parameters and their brief description. If a function has no parameters, they are not specified. Parameters are passed in the format parameter=value.

Result: results may vary depending on the requested function:

List of elements (table)

The XML document will look like this:

<?xml version="1.0" encoding="UTF-8"?>
	<elem>element parameters on the list</elem>
	<elem>element parameters on the list</elem>
	<elem>element parameters on the list</elem>

Result: only the element parameters are described. They are one or several XML-nodes containing all possible attributes and values. For example:

<?xml version="1.0" encoding="UTF-8"?>
		<user used="1" limit="10"/>
		<disk used="0" limit="10"/>
		<traf used="3542" limit="8192"/>
		<user used="5" limit="50"/>
		<disk used="39" limit="50"/>
		<traf used="1084" limit="4096"/>

List of object parameters (form)

The XML document will look like this:

<?xml version="1.0" encoding="UTF-8"?>
    <elid>unique object ID</elid>
    object parameters

Result: the object parameters are only described. These are one or several XML nodes with all possible attributes and values that describe the properties of that object. For example:

<?xml version="1.0" encoding="UTF-8"?>

Successful operation (action)

When creating, changing, removing, enabling or disabling an object, the XML document will look like this:

<?xml version="1.0" encoding="UTF-8"?>

Delete requests return a response code of "200" even if no record is found. To verify that a record has been deleted, you can submit a request to edit the record. If the record is deleted, the request returns an error message.

Error message

If an error occurred while processing your request, the XML document will look like this:

<?xml version="1.0" encoding="UTF-8"?>
	<error>error message.</error>

List of functions and parameters

Parameters and Function of every control panel are described in separate articles of our Documentation (the articles are generated automatically). They contain all of the functions and parameters, which, however, may be not available in your installation.

Read more in the BILLmanager API.

Use the mgrctl -i utility to get up-to-date information

To get a full list of BILLmanager functions, you may execute the command

/usr/local/mgr5/sbin/mgrctl -m billmgr -i

To get data description (the lang parameter can be used to get information in a required language)

/usr/local/mgr5/sbin/mgrctl -m billmgr -i user lang=ru

How to generate an API request using the log file

The most convenient way to generate an API request is to perform a desired action in the panel interface and view the function and its parameters in the log file.

Complete the following steps:

1. Open the log file of the control panel with the tail command:

tail -f /usr/local/mgr5/var/XXXmgr.log | grep Request

where XXX is a short name of the control panel. For example bill, isp, vm, dci

2. Execute a required action in the interface of the control panel. In the log file, you will see the function being executed at that moment, and its parameters (it is shown in green color starting from INFO Request).

For example, creating of a domain name in ISPmanager log file looks like this:

Feb  6 08:08:07 [2346:23826] core_module INFO Request [][root] 'clicked_button=ok&email_inaccess=&func=domain.edit&ip='

Let's generate the API request based on the function.

An API request must have the format https://<IP or domain name>:<the main port of the control panel>/<a short name of the control panel>?func=<function>&<parameter 1>=<value>&<parameter 2>=<value>...

Remove optional parameters from the request (sfrom, operafake, progressid, parameters equal to * and empty parameters), and create the API request:
