In order for PayFabric payments to write back to WebPortal, you need to fill out the Return URL in your PayFabric device’s Transaction Options.
This option can be found in the PayFabric portal under Settings > DevCentral.
There is a large blue bar under Device Name where you can select your device. Make sure this matches the device you currently have set up in SalesPad.
Once you have selected your device, click Transaction Options and scroll down until you see Return URL. In this field, enter https://portal.salespad.net/payfabric-return.html, replacing the portal.salespad.net portion with your portal’s URL.
