Authorize.net is quite possibly the world's most popular online credit card processing company. Your customers will prefer paying with credit cards 9 times out of 10; having an Authorize.net account is a vital step for your business. Its purpose is to handle your customer's credit card information and ultimately transfer credit card revenues into your bank account.
Cart Ninja is fully equipped to integrate with Authorize.net allowing you to offer every major credit card (Visa, Master Card, Discover, and American Express) as a payment method for your customer.
After you have signed up for an Authorize.net account you will need to find your API Login ID and Transaction Key. These two things allow Cart Ninja to communicate with your account and transfer credit card payments from your customers to you.
Step 1. Login to your Authorize.net account.
Step 2. Click on Account (Top Right) and then click on API Login ID and Transaction Key (lower bottom right).
Step 3. You will then see your API Login ID, and underneath your API Login ID you will see a place to generate your Transaction Key. Keep these secure and in a location that you can remember them. Copy and Paste both into their respective fields in your Cart Ninja Settings.
Step 4. Make sure Test Mode is Turned Off
Step 5. We also recommend disabling the Address Verification service (enabled by default), by setting it to "Allow plus report" (See Video).
