[PostFinance] What happens if the acquirer’s payment gateway is unavailable?

If your acquirer’s payment gateway is unavailable, there are 2 different ways in which your transactions can be processed:
Firstly we can store the transaction and send it to your acquirer as soon as the gateway is available again. This is known as “offline” or “store & forward processing”. Here you will receive a “pending” status for the transaction the moment you submit it.
The second option is to bar offline processing, in which case the transaction status will be set to “2 Authorisation Refused”.
You can configure this in the Technical Information of your account under point 6.
