== LDAP example ==
This page documents VoIPmonitor's Web APIs for programmatic access to CDR data, recordings, active calls, and system functions.


You can find complete LDAP example in GUI directory under scripts/ldap_custom_login_example.php
== Overview ==
Make sure that the php-ldap package or related is installed in the OS hosting the ldap script.

= CDR HTTP API =
Include <code>user</code> and <code>password</code> parameters in every request:


This method allows to get CDR rows formatted in JSON which you can see in the WEB GUI using the same filter which you can see in the WGB GUI: [[Call_Detail_Record_-_CDR#Filter_Form_button]]
<syntaxhighlight lang="bash">
curl 'http://server/php/api.php?task=getVoipCalls&user=USER&password=PASSWORD&params=...'
</syntaxhighlight>


You need to have valid session [[GUI_automate_login]] and you have to send those parameters via POST request
{{Note|1=API authentication uses local VoIPmonitor database credentials. It does NOT use LDAP or custom_login.php.}}


For disable authorization (if you are in safe environment) you can use 'GUI->Settings->System Configuration->Disable authorization for API usage' option.
'''Rate Limiting:''' Enable in GUI > Settings > System Configuration > "API maximal concurrent connections".


== CURL IMPORTANT NOTES ==
=== getVoipCalls ===


* for entering special characters in curl (e.g. + in caller option) is needed to use -G plus --data-urlencode options
Retrieve CDR records by search criteria.


curl -G -X GET 'http://localhost/php/api.php?task=getVoipCalls&user=USER&password=PASSWORD' --data-urlencode 'params=[{"startTime":"2013-01-01","endTime":"2013-08-01","caller":"910251414"},{"startTime":"2013-01-01","endTime":"2013-08-01","caller":"1+1","customHeaders":"Cell-ID-Caller,Cell-ID-Called"}]'

= HTTP API 2 =  
== Custom Login (LDAP/SSO) ==


It's preferred. This API was created for getting audio files based on various search criteria. Requests are over HTTP POST or GET.
Custom authentication via <code>scripts/custom_login.php</code>. This applies to GUI login only, NOT to API authentication.


== Rate limit ==
=== Basic Structure ===


You can enable it in GUI->Settings->System configuration->API maximal concurrent connections
<syntaxhighlight lang="php">
<?php
function custom_login($user, $password) {
    // Authenticate against external system (LDAP, etc.)
    // ...


The limit is set per user.
    return array(
 
        'username' => $user,
== getVoipCalls ==
        'id' => $uniqueNumericId,  // REQUIRED: Must be unique per user!
 
        'is_admin' => false,
=== Input data ===
        'id_group' => 1,          // Optional: GUI group ID
 
        'enable_sensors' => array(1,2,3) // Optional: restrict to sensors
*startTime - all calls which started >= startTime
     );
*startTimeTo - all calls which started <= startTimeTo (not mandatory)
}
*callEnd - all calls which ends <= callEnd (not mandatory)
?>
*caller - caller number
</syntaxhighlight>
*called - called number
*callId - Call-ID
*id_sensor - sensor's number
*msisdn - when you enter caller and called then cond is 'caller = 9999999 and called = 9999998'. With msisdn the cond is 'caller = 9999997 or called = 9999997'
*cdrId - ID number in db
*onlyConnected - 0 or 1 - get only connected calls or all calls (ringing)
*[custom header name]: [custom header value], seach cdrs by this custom header value
*customHeaders - the names of the returned custom header's values

'''Summary:''' VoIPmonitor Web API reference with two main APIs: (1) HTTP API 2 at <code>/php/api.php</code> using user/password authentication for tasks like getVoipCalls, getVoiceRecording, getPCAP, listActiveCalls, getShareURL, handleActiveCall, reportSummary; (2) CDR HTTP API at <code>/php/model/sql.php</code> using session cookies with full GUI filter support. Critical: correct endpoint path is <code>/php/api.php</code> (not <code>/api.php</code>). reportSummary requires pre-configured reports in GUI. Custom login via <code>scripts/custom_login.php</code> enables LDAP/SSO - requires unique numeric ID per user to avoid shared settings. Antivirus may delete scripts with shell_exec - disable with DISABLE_ANTIVIRUS or move to external file. Branding: BRAND_NAME for product name, BRAND_SHARESITE/BRAND_DOMAIN in brand.php for custom share domain.

VoIPmonitor Web API

This page documents VoIPmonitor's Web APIs for programmatic access to CDR data, recordings, active calls, and system functions.

Overview

API Endpoint Authentication Use Case
HTTP API 2 /php/api.php user/password params CDR queries, recordings, PCAP, active calls
CDR HTTP API /php/model/sql.php Session cookie Advanced CDR filtering with GUI filters

⚠️ Warning: Correct path is critical: Always use /php/api.php (not /api.php). Missing the /php/ directory causes "action parameter missing" errors.

HTTP API 2

Preferred API for programmatic access. Requests via HTTP POST or GET to /php/api.php.

Authentication

Include user and password parameters in every request: 

curl 'http://server/php/api.php?task=getVoipCalls&user=USER&password=PASSWORD&params=...'

ℹ️ Note: API authentication uses local VoIPmonitor database credentials. It does NOT use LDAP or custom_login.php.

Rate Limiting: Enable in GUI > Settings > System Configuration > "API maximal concurrent connections".

getVoipCalls

Retrieve CDR records by search criteria.

Parameters:

Parameter Description
startTime Calls starting >= this time (required)
startTimeTo Calls starting <= this time
callEnd Calls ending <= this time
caller / called Caller/called number
callId SIP Call-ID
cdrId Database ID
id_sensor Sensor number
msisdn Match caller OR called (instead of AND)
onlyConnected 1 = only answered calls
customHeaders Comma-separated custom header names to return

Examples: 

# HTTP GET - by time range and caller
curl 'http://server/php/api.php?task=getVoipCalls&user=USER&password=PASSWORD&params={"startTime":"2024-01-01","startTimeTo":"2024-01-31","caller":"123456"}'

# HTTP POST - by Call-ID
echo '{"task":"getVoipCalls","user":"USER","password":"PASSWORD","params":{"startTime":"2024-01-01","callId":"abc123"}}' | curl -X POST -d @- http://server/php/api.php

# With custom headers
curl -G 'http://server/php/api.php?task=getVoipCalls&user=USER&password=PASSWORD' \
  --data-urlencode 'params={"startTime":"2024-01-01","caller":"123","customHeaders":"X-Custom-Header"}'

Response fields:

Field Description
cdrId Database CDR ID
id_sensor Sensor ID
calldate / callend Call start/end time
duration / connect_duration Total / connected duration
caller / called Caller/called numbers
sipcallerip / sipcalledip SIP endpoint IPs
codec_a / codec_b Audio codecs
lastSIPresponseNum (New in 2026.1) Final SIP response code (e.g., 200, 404, 503)
callId SIP Call-ID

getVoiceRecording

Download audio recording (WAV format).

Parameters:

Parameter Description
cdrId Database CDR ID (preferred)
callId SIP Call-ID
calldate Date hint (default: today)
zip true = return ZIP archive
ogg true = return OGG format
saveaudio_afterconnect "yes" = audio only after call connect

Examples:

Share CDR Configuration

Share Link Types

Use /php/model/utilities.php with task=shareCdr:

Type subType Description
Local Public self_protected_link Password-protected local link
Local Private self_login_link Requires GUI login
voipmonitor.org share_link Public via share.voipmonitor.org

Custom Branding

Product Name: Edit config/system_configuration.php: 

define('BRAND_NAME', 'YourCompany');

Share Domain: Edit brand.php to use your domain instead of share.voipmonitor.org: 

define('BRAND_SHARESITE', 'share.yourdomain.com');
define('BRAND_DOMAIN', 'yourdomain.com');

Custom Login (LDAP/SSO)

Custom authentication via scripts/custom_login.php. This applies to GUI login only, NOT to API authentication.

Basic Structure

<?php
function custom_login($user, $password) {
    // Authenticate against external system (LDAP, etc.)
    // ...

    return array(
        'username' => $user,
        'id' => $uniqueNumericId,  // REQUIRED: Must be unique per user!
        'is_admin' => false,
        'id_group' => 1,           // Optional: GUI group ID
        'enable_sensors' => array(1,2,3)  // Optional: restrict to sensors
    );
}
?>

⚠️ Warning: The id field MUST be unique per user. If multiple users return the same ID, they share ALL settings (timezone, dashboard, etc.). Use LDAP uidnumber or crc32($email) for uniqueness.

LDAP Example

See scripts/ldap_custom_login_example.php in GUI directory.

Requirements: php-ldap package installed.

Debug from CLI: 

cd /var/www/html/scripts/
php custom_login.php

Enable debug by uncommenting the debug block at top of script.

Troubleshooting

Users share settings: Return unique id per user (see warning above).

LDAP users can't view CDRs: Ensure is_admin => false and correct id_group is returned.

Script being deleted: GUI antivirus deletes scripts with shell_exec(), exec(), etc.

Solutions:

  1. Disable antivirus in config/system_configuration.php:
define('DISABLE_ANTIVIRUS', true);
  1. Or move shell commands to external file outside web directory and require_once() it.

Azure AD / Microsoft SSO

For Microsoft Entra ID integration, see Microsoft_Sign_in_usage. For Google, see Google_Sign_in_usage.

AI Summary for RAG

Summary: VoIPmonitor Web API reference with two main APIs: (1) HTTP API 2 at /php/api.php using user/password authentication for tasks like getVoipCalls, getVoiceRecording, getPCAP, listActiveCalls, getShareURL, handleActiveCall, reportSummary; (2) CDR HTTP API at /php/model/sql.php using session cookies with full GUI filter support. Critical: correct endpoint path is /php/api.php (not /api.php). reportSummary requires pre-configured reports in GUI. Custom login via scripts/custom_login.php enables LDAP/SSO - requires unique numeric ID per user to avoid shared settings. Antivirus may delete scripts with shell_exec - disable with DISABLE_ANTIVIRUS or move to external file. Branding: BRAND_NAME for product name, BRAND_SHARESITE/BRAND_DOMAIN in brand.php for custom share domain.

Keywords: web api, http api, api.php, sql.php, getVoipCalls, getVoiceRecording, getPCAP, getShareURL, listActiveCalls, reportSummary, handleActiveCall, CDR filter, custom login, LDAP, authentication, session, curl, JSON, branding, BRAND_NAME, BRAND_SHARESITE, antivirus, DISABLE_ANTIVIRUS, unique user id, uidnumber
