HI there can you please tell me that what are connector-guid, user-guid and api key in below given code and how to get them for any website?

<pre>
<?php

$userGuid = "8f65f01f-c6bc-42a4-914d-879efd159abd";
$apiKey = "private";

// Issues a query request to import.io
function query($connectorGuid, $input, $userGuid, $apiKey) {

    $url = "https://query.import.io/store/connector/" . $connectorGuid . "/_query?_user=" . urlencode($userGuid) . "&_apikey=" . urlencode($apiKey);

    $ch = curl_init($url);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array(
        "Content-Type: application/json",
        "import-io-client: import.io PHP client",

    ));
    curl_setopt($ch, CURLOPT_POSTFIELDS,  json_encode(array("input" => $input)));
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_HEADER, 0);
    $result = curl_exec($ch);

1. User-guid is a your import.io user unique identificator. You might see it at your user's settings' page.
2. Connector-guid is a unique identifier for each connector in general sence, it might be a connector, a crawler, an extractor. It's issued for each api connector automatically. You might get it for each api piece. See the data page. Below is an example of crawler with the connector-guid (in a white box):
3. API key is your unique key to all your api. It's renewable (you might generate a new one). Just enter your account page, get to the API key line and input your password to unlock api key. Read more here how to get an api key. Unlocked api key:

Answer 2

Not sure but here is what i think. I think connectorGuid is some random key used to create the link to the web api.
The apiKey is obviously the api key.
userGuid again is some identification of records
All web apis are not the same so you cant get api details of any website
