Appendix 1. External fee for payments

The possibility of using this functionality by the seller must be agreed with the Bank.

Addition to the description of the payment page

In the settings of the payment script (in the page header), you must enable checking for the presence of a payment fee:

        getFeeEnabled: true
    

The payment script executes a request to the payment gateway to determine whether a fee is required. In case of a positive response, the fee amount is displayed on the payment page.
To do this, the following block must be present in the page body:

        <div id="feeBlock" class="row" style="display: none;">
  <div class="price">
    <span class="size24">
      <div id="feeAmount" style="float: left; margin-right: 8px;">0.00</div>
      <img src="images/ruble.gif" id="fee-ruble-sign" class="ruble-img" style="display: none; float: right;"/>
    </span>
  </div>
  <div class="name"><span>Payment fee</span></div>
</div>
