A: If a gateway fails the credential handshake, UltraCart will automatically choose one of the other configured gateways for subsequent transactions. So the first thing you will want to do is verify that the gateway credentials are accurate and active. Some gateways, like Authorize.net, will automatically expire the "Transaction Key" 24 hours after a new transaction key is generated. So, if in testing it appears not to be working , you may need to go back in there and review the active transaction key and potentially generate a new one.
Q: I wish to configure rotating gateways with the PayPal Payments Pro ("Direct Payments") are their any special precautions using this gateway in a rotating gateways configuration?
A: Yes. Specifically, the migration tool with NOT work IF you initially configured paypal settings using the "3rd Party" API credentials. You'll need to use the "First Party" credentials in the rotating gateways configuration. Log into your PayPal account and gather the 1st party API credentials (write down the "API Username", " API Password & "Signature" credentials.) Then navigate to the "Multiple (Rotating) gateways" configuration page and then click the new button and fill out the top section of the editor with a RTG code, then set as "Active" then configure the traffic percentage as 100.00%. After configuring the PayPal Payments Pro gateway, add the secondary gateway(s).
