### Example XML request

```xml
<?xml  version="1.0" encoding="utf-8" ?>
<request>
   <security>
      <login value="login" />
      <password value="password" />
   </security>
</request>
```

{% hint style="info" %}
The number of SMS cannot be summarized for different directions. When sending SMS in one direction, the number of available SMS messages in all other directions is reduced according to their cost.
{% endhint %}

### Example

You have 10 y.e. on your balance.&#x20;

The cost of SMS message sent to Russia is 1 y.e.&#x20;

The cost of SMS message sent to Ukraine is 2 y.e.&#x20;

The following XML document will be returned to you:

```xml
<?xml version="1.0" encoding="utf-8" ?>
<response>
     <money>10</money>
     <sms area="Russia">10</sms>
     <sms area="Ukraine">5</sms>
</response>
```

If you send two sms to Russia, the XML document will change as follows:

```xml
<?xml version="1.0" encoding="utf-8" ?>
<response>
     <money>8</money>
     <sms area="Russia">8</sms>
     <sms area="Ukraine">4</sms>
</response>
```
