Integrating Authorize.net
Once you have your authorize.net account established the next step is simple. All you need to do is two things: Find your “API Login Id” and your “Transaction Key” from within your Authorize.net account.
Here are specific instructions:
1) Login to your Merchant Account at www.authorize.net (You’ll need your account login ID and password)
2) In the left column under ACCOUNT you need to click on Settings
3) In the middle section called SECURITY SETTINGS there is a link called “API Login ID and Transaction Key”. Click this link. (See below)

4) Your API Login ID will be listed there and then you’ll need to generate your Transaction Key.
NOTE: Once you generate your Transaction Key DO NOT reset it and do not generate it again. This will cause our system to be disconnected from your account. If you must reset your Transaction Key please make sure to copy the new key into your account Payment Options and run some tests to ensure that everything is working properly.
5) Within your Authorize.net account you need to make one more mandatory modification. Under: Settings/Payment Form/Form Fields you should modify the setting there to match the screenshot below. If you’re MAILING tickets please include the checkbox to collect the user’s mailing information as well.

6) After you have your account integrated with the ETS system, please run a test transaction before making your tickets live. Run a live credit card to make sure that everything works properly from end to end. You can always refund the test from within your Authorize.net account. You may also consider emailing us so we can look over your account and do some testing too just to give you peace of mind. We have no control over what Authorize.net does so it’s always better to test first.
7) Please note that you have other controls within Authorize.net to customize the look of your payment page. The page appears without any additional graphics or navigation by default so you can opt to modify the look of the page as needed.
