Receiving exception when attempting to integrate an API using PHP - php

Question

Currently, I am working on integrating a chat API (it is called pusher Chatkit) to an app I am working on. For the backend, PHP and laravel are being used, and postman is being used to test the server. When testing on Postman I am receiving a 500 internal server error with this exception:
{
"message": "You must provide an instance_locator",
"exception": "Chatkit\\Exceptions\\MissingArgumentException",
"file": "/Users/shaquilenoor/Desktop/chatapi/vendor/pusher/pusher-chatkit-server/src/Chatkit.php",
"line": 49,
"trace": [
in trace, many files/lines are referred to, so I left out as it is too much to fit in this post (you can ask if needed though and I can make a Gdrive link with it in)
The code leading up to the line + function being referred to is this:
<?php
namespace Chatkit;
use Chatkit\Exceptions\ChatkitException;
use Chatkit\Exceptions\ConfigurationException;
use Chatkit\Exceptions\ConnectionException;
use Chatkit\Exceptions\MissingArgumentException;
use Chatkit\Exceptions\TypeMismatchException;
use Firebase\JWT\JWT;
class Chatkit
{
protected $settings = array(
'scheme' => 'https',
'port' => 80,
'timeout' => 30,
'debug' => false,
'curl_options' => array(),
);
protected $logger = null;
protected $ch = null; // Curl handler
protected $api_settings = array();
protected $authorizer_settings = array();
protected $cursor_settings = array();
const GLOBAL_SCOPE = 'global';
const ROOM_SCOPE = 'room';
/**
*
* Initializes a new Chatkit instance.
*
*
* #param array $options Options to configure the Chatkit instance.
* instance_locator - your Chatkit instance locator
* key - your Chatkit instance's key
* scheme - e.g. http or https
* host - the host; no trailing forward slash.
* port - the http port
* timeout - the http timeout
*/
public function __construct($options)
{
$this->checkCompatibility();
if (!isset($options['instance_locator'])) {
throw new MissingArgumentException('You must provide an instance_locator');
}
if (!isset($options['key'])) {
throw new MissingArgumentException('You must provide a key');
}
$this->settings['instance_locator'] = $options['instance_locator'];
$this->settings['key'] = $options['key'];
$this->api_settings['service_name'] = 'chatkit';
$this->api_settings['service_version'] = 'v2';
$this->authorizer_settings['service_name'] = 'chatkit_authorizer';
$this->authorizer_settings['service_version'] = 'v2';
$this->cursor_settings['service_name'] = 'chatkit_cursors';
$this->cursor_settings['service_version'] = 'v2';
foreach ($options as $key => $value) {
// only set if valid setting/option
if (isset($this->settings[$key])) {
$this->settings[$key] = $value;
}
}
}
The instance_locator refers to a code generated on Pusher Chatkit, which I link in my files for integration of that API. This is my first time integrating a backend server using PHP so a little lost! Would appreciate some advice on where I should be looking to solve the issue and also more than happy to provide further info. Cheers

Depending on how you create API request you should do something like this:
$chatkit = new Chatkit(['instance_locator' => *locator*, 'key' => *actualKey*]);
The error you are getting means that you haven't passed variables in array.
