The gateway requires some configuration before it can be used with Rezgo. First, because of the international nature of Rezgo bookings, the system does not support AVS. However, the system does support CVV. In order for the payment gateway to work properly with your account, you must update your settings with the following:

  1. Enable CVV
  2. Disable AVS (see instructions below)
  3. Use your API Login ID and create a Transaction Key. (these are used in your payment gateway configuration settings on Rezgo).
  4. In the “Direct Response” section of the settings, be sure to set the default delimiter as a “|” Pipe and set the encapsulator to blank.

To disable AVS:

  1. Go to “Settings” then “Address Verification Settings”
  2. Remove any checkboxes next to “Reject Transaction”.
