To accept credit cards, you’ll need a merchant account and a gateway. Authorize.net is the gateway of choice for many merchant account providers. This is because they are one of the largest gateway providers in the US. Reliability and security are obviously important when it comes to accepting credits cards and they are both. The Authorize.net payment module for Zen Cart is one of the default payment modules making it a smooth integration with your store.
If you already have a merchant account the question to ask them is ‘Do you offer authorize.net as payment gateway?’.
If you are just starting out, visit the Authorize.net website for a list of merchant account providers and find the one that best suits your needs and budget.
You *will* need an SSL certificate installed on your site in order to use this. The simple reason is you need to secure the credit card information you are transmitting from your site to authorize.net when completing the transaction. Most hosting companies will sell you an SSL and install it for you. If you have questions or problems, feel free to contact us.
The configuration requires just the Login ID and Transaction Key to get going. The other settings will depend on your particular needs as a store owner. If you need or want help, we do offer a module installation service.
