Learn how to accept open banking payments

Open banking is also known as "open bank data." Open banking is a banking practice that provides third-party financial service providers open access to consumer banking, transaction, and other financial data from banks and non-bank financial institutions through the use of application programming interfaces (APIs).
You can now accept SEPA bank transfers from European banks from your customer using our new OpenBanking PIS API.

When the customer finished or canceled the payment, he will be redirected back to url_return, provided by you in the initial request to payment_preauthorize. After that, you will receive a notification, posted to notification_url, with the final transaction status, which you suppose to use to update your system.

Notification URL can be configured by our tech support team in your account on our side,
or you can send it as a parameter notification_url in the initial request to payment_preauthorize.

Notification example

"transactionid=116033311&type=capture&security=67cf6863d378sdfdsfdsaeb91dc5a9c072f7f1&
errormessage=&errorcode=0&orderid=743222831" "https://www.notification_url"

📘

url_return and notification_url should be provided by you to payabl. technical team.

payabl. contains an additional notification parameter which is payment_state, which could contain the following values:

  • not_credited_yet: Capture - Accepted.
  • credited: Capture - Successful.
  • not_credited: Capture - Failed.
    Each state change would trigger a notification to the notification URL. The notification URL is the URL that was provided when the merchant account was created.

Final transaction status update

You will receive a notification from payabl. regarding the status update of the transaction. If payabl. received funds from the issuer for the transaction you will get the following notification:

Notification example

"payment_method=123&iban=TE000XXXXXXXXXXXXXXX&payment_state=credited&timestamp=1645624574&orderid=Payabl-Test&errorcode=0&transactionid=147783364&type=capture&bic=CBVILT2X&

"http://83.169.19.140/simulation/billing_response.php"

In case 10 days pass and payable. didn't receive any funds from an issuer, the transaction will be failed automatically. You will receive a notification update.
