AlexaCRM for PHP: Creating Incident (Case) in Dynamics CRM using CRM toolkit

When I started investigating this Stack Overflow question - I noticed that not a lot of online resources were available. Also some online IDE like codepen to test the snippet is totally missing and causing more trouble.

Download: AlexaCRM - php-crm-toolkit

Key learning is the below prerequisites:

use AlexaCRM\CRMToolkit\Client as OrganizationService;

use AlexaCRM\CRMToolkit\Settings;

use AlexaCRM\CRMToolkit\Entity\EntityReference;

Otherwise some errors like this will give you hard time. Fatal error: Uncaught Error: Class 'EntityReference' not found

I gave some hints & OP was able to come up with the working code: The complete code snippet is below:

<?php
/**
 * Use init.php if you didn't install the package via Composer
 */
require_once 'vendor/autoload.php';

use AlexaCRM\CRMToolkit\Client as OrganizationService;
use AlexaCRM\CRMToolkit\Settings;
use AlexaCRM\CRMToolkit\Entity\EntityReference;

$options = [
    'serverUrl' => '**************************',
    'username' => '**********************',
    'password' => '*****************',
    'authMode' => 'OnlineFederation',
];


$serviceSettings = new Settings( $options );
$service = new OrganizationService( $serviceSettings );

$contact = $service->entity( 'contact' );
$contact->firstname = 'John';
$contact->lastname = 'Doe';
$contact->emailaddress1 = 'john.doe@example.com';
$guid = $contact->create();

$incident = $service->entity('incident');
//echo '<pre>';print_r($incident);echo '</pre>';
$incident->title = 'Test Created With Proxy';
$incident->description = 'This is a test incident';
$incident->customerid = new EntityReference( 'contact', $guid );
//$incident->ID = $guid;//contactid responsiblecontactid primarycontactid
$incidentId = $incident->create();
?>

It may help someone. :)
