This page describes the processing of integration errors.
If you would like to customize how you handle errors that occur when a transaction is rejected, see the following article:
For embedded form, errors are automatically displayed in the kr-form-error div:
<!-- error zone --> <div class="kr-form-error"></div>
<!-- error zone --> <div class="kr-form-error"></div>
All you need to do is add it to your code.
To handle errors manually, simply intercept the default error message and customize it. In the following example, the custom error message will be placed in the customerror class div:
<script type="text/javascript"> $(document).ready(function() { KR.onError( function(event) { var code = event.errorCode; var message = event.errorMessage; var myMessage = code + ": " + message; try { /* if client answer exists, a refused transaction has been created */ /* it's not always the case. For example, if the form is empty, */ /* error is raised before transaction creation */
The REST API has different error codes described here: REST API error codes.
The error codes that start with CLIENT_ correspond to errors occurring in the Buyer's browser. They occur before the payment data is sent to our servers. This concerns, for example, local form data validation errors or JavaScript client integration errors.
