IPN messages

💵 Invoice payment status updates​

There is an option for the web store (or other business application) to receive notifications about the payment status of an invoice via IPN (Instant Payment Notification). This message is sent by Számlázz.hu to the specified web address in a POST message with "Content-Type": "application/form-data". The URL can be specified within the billing account on the Fiók beállítások / Számlázás alapadatok page.

In the event that the payment status of an invoice changes, Számlázz.hu sends an HTTP request to the URL specified in the settings:

  • szlahu_szamlaszam - the number of the settled invoice
  • szlahu_dijbekero_szama- the parent pro forma invoice number, if the invoice was created based on a pro forma invoice
  • szlahu_rendelesszam - order number, if it was included on the invoice
  • szlahu_bruttovegosszeg - the gross total amount of the invoice
  • szlahu_kifizetettbrutto - the paid amount, in case of a settled invoice this equals the gross total amount
  • szlahu_fizetesmod - the method of payment
  • szlahu_kifizdat - the date of payment in YYYY-MM-DD date format
info

The szlahu_kifizdat IPN message is not activated by default. If you wish to utilize this feature, our customer service team will be happy to assist you in setting it up. Please contact our customer service representatives!

danger

Our system does not send IPN as a real-time background process; instead, we attempt to send the payment information to the URL specified in the account every 3 minutes. We will try ten times, and if we do not receive an HTTP 200 OK response (indicating that the receiving server has received, accepted, and understood the message) during this period, we will stop attempting further and the IPN will be discarded.
