I need After-ship API integration for e-commerce website.

https://www.aftership.com/docs/api/4

which will be useful in tracking the order status.

I have downloaded sdk from

https://github.com/abishekrsrikaanth/aftership-php-sdk

I have given the api key in AfterShip/Core/request.php.

But its not working can anyone suggest me steps to integrate it.

I tried , but i am not getting response

<?php 
require 'Core/Request.php';
require 'Couriers.php';
$courier = new AfterShip\Couriers('API-KEY');
$response = $courier->get();

echo $response;
?>

Did you use your own API key? Check if the object is valid, then check what exactly is in the reponse. Any errors in your error log?
