For Direct integration method, IRIS can only be used via QR code.

When IRIS is chosen as a payment method during the checkout, a Sale Request is sent from merchant’s server requesting for the QR code data.

Part of the XML response returned from the payment gateway is the Base64 encoded QR value. This value should be displayed to the buyer as an inline base64 image. Then the payer can scan it using the respective m-banking app.

You may find more details here.
PayMethod and PaymentOption should be taken into consideration regarding the request. Attributes “IRIS-QR" and “IRIS-TXID" regarding the response.

Sample request can be found here.

The transaction is initially in PROCESSING status.
In order to be informed about the result of the transaction, XML StatusRequest should be used to retrieve transaction’s status.
As long as the status is not final (CAPTURED, REFUSED, ERROR, TIMEDOUT, CANCELED, PROCESSING-TIMEDOUT), then the StatusRequest should be used again.

Relative sample request can be found here.

For Redirect integration method, IRIS is provided as an option within the payment page.

There is no need for further implementation since the IRIS option is automatically available in the payment page for the payer to choose.

The only prerequisite is to use the latest payment page which looks like below (could be slightly different if you have applied customization):

If you are using a different payment page, please contact ecommerce_support@cardlink.gr.

If you wish, you can provide IRIS as a separate payment method in your checkout page and declare that you wish the payment to be made through IRIS by using parameter payMethod=’IRIS’. By doing that, customer directly sees the page with Bank logos and QR generation and can choose how to proceed.

After a successful IRIS transaction, in the response message you will receive the respective parameter payMethod=’IRIS’.

How to test IRIS functionality

To begin with, you need to enable IRIS during a new app creation or through an existing app modification.
During new app creation, choose Worldline as Business partner and Redirect or Redirect/Direct as Model.

Post the respective request – using parameter payMethod=’IRIS’ if you wish – to open the payment page.
Choose the IRIS tab on the top right of the page to show IRIS details. If you use payMethod=’IRIS’, then you will be moved there directly.

In test environment, IRIS can be tested up to the point of the payment page where the Bank logos and QR generation button appear.
After that point, you can only proceed with the QR generation, however it cannot then be used somehow to complete the transaction.
