Installation

SEB e-commerce payment solution extension is available on website free of charge: support.ecommerce.sebgroup.com

Whenever possible, the extension should first be installed on development and/or staging environments before deploying it to the production server.

1. Download OpenCart extension on SEB e-commerce Support website. In the OpenCart site administration panel open “Extensions”, then “Installer” and  “Upload File”. Select the previously downloaded file and wait until the file is uploaded.
2. In the OpenCart site administration panel open “Extensions”, then “Extensions” and in the drop-down menu “Payments”. Click “Install” “SEB Payment Gateway” payment method.

Configuration
Once the extension is installed, it can be configured via Extensions → Payments → SEB Payment Gateway

Due to the reason that some banks do not support 3DS inside the iFrame, we recommend to set up redirect payment flow.

Callback notification set up in merchant portal
Callback notifications must be used to inform updated status of the payments. When the payment is finalized, a customer notification is sent to the callback URL. Notifications include fields payment_reference and order_reference.
You can set the callback URL in the Merchant Portal under E-shop Settings, and it can be found in module settings.

SEB e-commerce payment solution has two separate Merchant Portals:
