Solution here, in git hub
https://github.com/zakir-hyder/Citrix-GoToWebinar-PHP-Library
you have to create application first, after provide details to the script:
$citrix = new Citrix('API Key');
$citrix->set_organizer_key('organizer_key');
$citrix->set_access_token('access_token');
code example:
<?php
include "citrix.php";
$citrix = new Citrix('API Key');
$citrix->set_organizer_key('organizer_key');
$citrix->set_access_token('access_token');
try
{
$organizer_key = $citrix->get_organizer_key();
$citrix->pr($organizer_key);
}catch (Exception $e) {
$citrix->pr($e->getMessage());
}
try
{
$webinars = $citrix->citrixonline_get_list_of_webinars() ;
$citrix->pr($webinars);
}catch (Exception $e) {
$citrix->pr($e->getMessage());
}
try
{
$response = $citrix->citrixonline_create_registrant_of_webinar('webinar id', $data = array('first_name' => 'First Name', 'last_name' => 'Lastnmae', 'email'=>'email#email.com')) ;
$citrix->pr($response);
}catch (Exception $e) {
$citrix->pr($e->getMessage());
}
try
{
$webinars = $citrix->get_registrants_of_webinars('webinar id') ;
$citrix->pr($webinars);
}catch (Exception $e) {
$citrix->pr($e->getMessage());
}
try
{
$citrix->citrixonline_delete_registrant_of_webinar('webinar id', 'registrant id') ;
}catch (Exception $e) {
$citrix->pr($e->getMessage());
}
