### Configuring Op Plug-in

The OP Bank Group's new electronic desktop allows you to handle your business on the Internet without visiting bank office in person. You can create your merchant account at an OP branch. After signing a contact you are given your Merchant ID and Merchant MAC (your verification code) which you further use to configure the Op plug-in in Provider Control Center as described below.

To configure the Op plug-in:

1. Type your Merchant ID and Merchant MAC obtained after registration into the Merchant ID and Merchant MAC fields respectively. The Op transaction server URL is provided by default in the Server URL field (https://kultaraha.op.fi/cgi-bin/krcgi).
2. Specify at least one credit card type to be accepted by the Op payment gateway from the Available credit card types menu. To select a credit card click and move it to the Supported Card Types menu using the >> button. To select several card types in series, hold down SHIFT, and then click the first and last card types of the group you wish to add to the Supported Card Types list. To select several card types that are nonadjacent in the list, hold down CTRL, and then click the credit card types you need.
3. Key in the Button title. For example, this could be the name of payment system. This title will be displayed directly on the button for online-payment at HSPstore, on the final stage of subscription registration, when a customer selects how to pay for the services ordered.
4. You can add both the short and the detailed description. Quick description of a payment method will be displayed below the button. The Long description of a payment method will be displayed in a separate section entitled Pay Online.
5. Press Update to save the plug-in configuration or Cancel to abolish the task.
