Error handling

There can be different reasons if Számla Agent does not create an invoice. Those reasons will not disappear without changing the call parameters in the XML.

Therefore, if a call is unsuccessful, recalling is prohibited. The maximum limit to send the same request to Számla Agent is five requests. If all of those requests are unsuccessful, please send an e-mail to the operator of your webshop and wait for their reply.

Számla Agent cannot be held responsible in the case an invoice could not be generated. If someone does not comply with these rules, or causes heavy server load without any reasons, then the parties who call the Agent will be banned.

In case the Számlázz.hu system is unavailable for whatever reason (application error, or system upgrade that requires downtime), the return call will be served by our CMS. You can check the response header for the szlahu_down: true attribute. If you see this header in the HTTP response, it indicates that it is not possible to create/query invoices from the system at the moment.
