Setting Up Authorizenet Gateway

How it Works

See Authorize.net's Credit Card Processing Diagram. Just click on “Step 1” then “Step 2” and so on.

Gateway Settings

For all gateways, be sure your account is set to active, rather than test mode.

Your gateway's website will have help menus that can assist you with set up.

Authorizenet API Login and Transaction Key

Once your merchant account has been approved, you will receive an email with the login information for your Authorizenet account. The first thing you need to do is log into the account, and fill out the initial registration page. You will be asked to generate a secret question and provide the answer. You will need to have the answer available in the future if you need to update your account. Then you will need to obtain an API Login ID and a transaction key from your Authorizenet account.

Here are the steps for getting up and running with Authorizenet:

Log in to your account at https://secure.authorize.net

If this is the first time you have logged in, fill out the form on the intial page, read over the license, and if the terms are agreeable, click to accept the agreement.

Navigate to Account > Settings > Security Settings > API Login ID and Transaction Key.

You will be prompted to create a transaction key. Once you have generated the key, you should jot down the API Login ID and copy the transaction key that you will paste into the Site Manager.

Entering API Login and Transaction Key into Your Site Manager

Version 4.x

In the MightyMerchant Site Manager, go to "settings" > Set Up Payment Gateway. Check off Authorizenet, then click Edit. Enter your API Login ID in the Merchant Login field, then paste the transaction key in the transaction key field. Set other information as desired, then click Save.

Version 3.x

In the MightyMerchant Site Manager, go to "Settings", then "Payment Options", check off the credit cards you accept, check off the Authorizenet checkbox and enter your API Login ID. Click to Save.

After you save these settings, you will need to scroll back up to the top of the page and click the "Set Transaction Key" link (you will be prompted to log in to the Site Manager again during this process).

Enter the transaction key you saved earlier.

Updating Your Transaction Key

Authorizenet recommends that you reset your transaction key on a regular basis. Any time you reset your transaction key on the Authoriznet website, you MUST enter the new key into the Site Manager by clicking the "Set Transaction Key" link in order for your auto-payment processing to work correctly on your website.
