Processing refunds for PostFinance

For businesses, it’s important to have the ability to process refunds if a customer requests them. There are two ways in which you can process refunds in PostFinance.

#1 Process refunds via the Post Finance BackOffice

You can process refunds on your PostFinance back-office account. To do this, simply login to either your test or production PostFinance account.

If you have any questions about processing refunds, we would highly recommend contacting The PostFinance support team, and they’ll be more than happy to respond to your concern.

#2 Process refunds via WooCommerce

Step 1 – Creating the API user.

You will need to create the API user, which the plugin will use to make API payment calls to the ePDQ system. You will need to go to Configuration > Users.

Here we want to add a new user; clicking the new user button shows us the following:

The most important element here is the tick box in the red box.   Special user for API (no access to admin.)”.
This will make this new user work with the API.

Note: Enter your desired UserID, User’s name, and email address.

You will need to enter your password, the one you signed in with. Once you do that, you will set this new API user password on another screen.

It’s important that for the API user passwords, please do use numbers and letters and no special characters used by the PostFinance system like £ since the PostFinance system will not allow this. The PostFinance system will not accept special characters that are used in code (e.g. £) to prevent someone from injecting bad code and compromising accounts. Alternatively, you could use a symbol like the exclamation mark !. An example password would be something like November5!. We recommend using another and more secure password as this is just an example that you could follow.

Step 2 – Plugin settings

Navigate to your WordPress dashboard > WooCommerce > Settings > Payments > AG Postfinance e-Payment Checkout > Manage and place the credentials of the API used on the fields below:

Step 3 – Processing the refund

Navigate to WooCommerce > Orders and then select the order that you wish to refund.

Click the ‘Refund’ button, and then additional fields would display.

Set the quantity and then click Refund via AG Checkout, and a few seconds or so, the order should have been refunded successfully.
