### Accepting callback from paysera

Check if callback from paysera is valid:
```javascript
var request = { data: ..., ss1: ... }; // the request data you got from paysera callback

var isValid = paysera.checkCallback(request);
if (isValid) {
  // Since callback seems valid decode callback data
  var order = paysera.decode(request.data);
  // Your code ... to update order status
  
  // Don't forget to return "OK" as the response.
}
```
