I have changed webhotel or it has changed IP, should I update anything in Quickpay-manager?
If you have changed webhotel og your webhotel/server have changed IP-address and you use API to handle your transactions, then you must remember to update or insert the new IP-address in the Quickpay-manager.
This is done under Settings -> API access. Add the new address on a new line and click Save. If the old IP-address is no longer needed, you can delete it, insert the new one and save.
