I use the following code which is tested with the wordpress API and codeigniter 3. You'll need to amend the $opts array.

$method would be post, get, put ...

$url the api url ...

$opts = array('https'=>array('method'=>"GET",'header'=>"Authorization: Bearer $token"));

public function CallAPI($method, $url, $opts = false)
{
$curl = curl_init();

switch ($method)
{
    case "POST":
        curl_setopt($curl, CURLOPT_POST, 1);

        if ($opts)
            curl_setopt($curl, CURLOPT_POSTFIELDS, $opts);
        break;
    case "PUT":
        curl_setopt($curl, CURLOPT_PUT, 1);
        break;
    default:
        if ($opts)
            $url = sprintf("%s?%s", $url, http_build_query($opts));
}

curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);

$result = curl_exec($curl);

curl_close($curl);

return $result;
}

// The following is your code but slightly amended to change the header and suggest Authorization which is commented out. I also removed some unnecessary curl. I changed your $data_array to include the header but try it in its original form as well but with content-Type as application/json.

 $url = "https://blabla.com/Auth/login";
    
 $data_array = array('username' => $username,'password' => 
 $password,'baseSessionID' => $baseSessionID,'ipAddress' => $ipAddress, 
'https' => array('header' => 'Content-Type: application/json','Auth-Key: 
 simplerestapi', 'Client-Service: frontend-client'));

    $data = http_build_query($data_array);
    /*
    $data1 = array(
        //'Content-Type: application/x-www-form-urlencoded',
        'Content-Type: application/json', 
        'Auth-Key: simplerestapi',
        //'Authorization: Basic '. base64_encode("app_key:app_secret")
        'Client-Service: frontend-client'
    );
    */
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
    //curl_setopt($ch, CURLOPT_HTTPHEADER, $data1);

    $reply=curl_exec($ch);
    
    if($e = curl_error($ch)){
        echo $e;
    }else{
        
        echo $decode = json_decode($reply,true);
    }
    
    curl_close($ch);
