===== Notes
Depending on exact **Payment Processor** and **Merchant Account** settings, this API call can be **time-limited**.
This means that some time period must pass between 2 successful calls.
If there are more calls with the same data within this period, this call could return failure.
Good approximation for this period is 5 minutes.
For **Rocket Gate** processor, this setting is available on **Merchant Admin** :
`BlockDupPurchaseTimer` - Minimum time between purchases using same card and amount.
==== Usage Example ====
```
<?php
$curl = new \Dinke\CurlHttpClient;
//setup payment url and timeout
$payment_url = 'https://dev-payment.datingvip.com/api.json';
$timeout = 30;
$curl->setCredentials('some-token', 'some-pass');
$post_data = array(
'cmd' => 'cards.update',
'data' => array(
'tracking_user' => '4151302',
'ccdt_id' => '393',
'card_number' => '5555555555554444',
'card_expire' => '1215',
'card_cvv2' => '123',
'first_name' => 'Pera',
'last_name' => 'Peric'
)
);
$response = $curl->sendPostData($payment_url, $post_data, null, $timeout);
if($response === false)
{
//handle errors
}
//decode json to get array
$response = json_decode($response, true);
var_dump($response);
```
