Set up PostFinance Account

    When the PostFinance payment provider is installed it should be configured in the PostFinance BackOffice and in Sana Admin. To configure the PostFinance payment provider and payment methods you should have the PostFinance test/ live account with all the necessary data.

Step 1: In the PostFinance BackOffice click: Configuration > Technical information > Global transaction parameters. Configure the Global transaction parameters.

The table below provides the description of the required settings.

Settings	Value
Default operation code	Select 'Sale'.
Processing for individual transactions	Select 'Online but switch to offline when the online acquiring system is unavailable'.

Step 2: Click: Configuration > Technical information > Global security parameters. Configure the Global security parameters.

The table below provides the description of the required hashing method settings.

Step 3: Click: Configuration > Technical information > Payment page.

Configure Back button redirection by specifying the URL of the webpage that should be shown to the customer when he clicks the "back" button on the PostFinance secure payment page.
