I am trying to get a list of deliveries using this GET call:
https://datalink.hconnect.digital/api-products/basic#get-https-//api.hconnect.digital/ecs/v2/deliveries

Here is a picture if the link is broken in the future

If i var_dump the response i get this:

“tring(22) “��)�L

If i write the response into a txt file using file_put_contents i get this
謟 躋묩ൌ

Here is my code

$AuthJSON = include ("APIAuthenticator.php"); // retrieves the accesstoken with a POST request

$jsonObject = json_decode($AuthJSON, false);

$accessToken = $jsonObject->access_token;
$tokenType = $jsonObject->token_type;

$customerIdParameter = "?customerId=redacted";
$startDateParameter = "&startDate=2024-06-01";//"&startDate=".date('Y-m-d',strtotime("-1 days"));
$endDateParameter = "&endDate=".date('Y-m-d',strtotime("-1 days"));


// Generated by curl-to-PHP: http://incarnate.github.io/curl-to-php/
$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, "https://api.hconnect.digital/ecs/v2/deliveries".$customerIdParameter.$startDateParameter.$endDateParameter);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'GET');

$headers = array();
$headers[] = 'Accept: application/json';
$headers[] = 'Content-Type: application/json; charset=utf-8';
$headers[] = 'Authorization: '.$tokenType.' '.$accessToken;
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

$result = curl_exec($ch);
if (curl_errno($ch)) {
    echo 'Error:' . curl_error($ch);
}
curl_close($ch);

var_dump($result);

file_put_contents("GetDeliveriesList_Output.txt", $result);

//return $resultObject;

When i try the API Call in Postman i get the correct JSON with all deliveries.

Also i tried it with Talend at first using the tRESTClient component.

Which looks like this

The output in Talend looks like this

In my php script i tried to convert the encoding to utf-8 from different ones but i only get different gibberish everytime.
