First, you will need to sign up for a Payment Gateway assuming you already have a merchant account with Authorize.Net.

Here is a link to get going with Authorize.Net

Once you have this all setup, we will need two pieces of information to place into your OnRes account – API Login ID and Transaction Key.

Once the API credentials are in place, you can set up other related payment options as needed at Interfaces -> Payment Gateway section.

For example, you can choose your Payment Type, which is set to control how guest credit cards are charged at the time of booking.

For charging the cards manually at the 2.0 system, this setting is not needed, as you can charge any amount from the card as needed.
