Answer

The API Login ID and Transaction Key are two pieces of information unique to your account. They are used to connect your website or other integrated business application to the Authorize.Net Payment Gateway for transaction processing. They are not valid for logging into the Merchant Interface.

API Login ID
The API Login ID is a complex value that identifies your account to the payment gateway when submitting transaction requests from your website. The API Login ID is at least eight characters in length, includes uppercase and lowercase letters, numbers, and/or symbols.

To obtain the API Login ID:

  1. Log into your Merchant Interface at https://account.authorize.net.
  2. Click Account from the main toolbar.
  3. Click Settings in the main left-side menu.
  4. Click API Credentials & Keys.

Your API Login ID is displayed on the page if one has been generated already. If not, enter your Secret Answer. The API Login ID will then be generated.

IMPORTANT: The API Login ID is sensitive account information and should only be shared on a need-to-know basis, for example with your Web developer for the purposes of integration with the payment gateway.

Transaction Key
The Transaction Key is a 16-character alphanumeric value that is randomly generated in the Merchant Interface and is used as an additional layer of authentication when submitting transaction requests from your website.

To obtain you're Transaction Key:

  1. Log into the Merchant Interface at https://account.authorize.net.
  2. Click Account from the main toolbar.
  3. Click Settings in the main left-side menu.
  4. Click API Credentials & Keys.
  5. Enter your Secret Answer.
  6. Select New Transaction Key.
  7. To disable the old Transaction Key, click the check box labeled Disable Old Transaction Key Immediately.
    (Note: If the Disable Old Transaction Key Immediately check box is not selected, the old transaction key will automatically expire in 24 hours.)
  8. Click Submit to continue. Your new Transaction Key is displayed.

IMPORTANT: The Transaction Key will not be visible at any other time in the Merchant Interface. You must record it temporarily or copy and paste it to a secure file location immediately. Like the API Login ID, the Transaction Key is sensitive account information and should only be shared on a need-to-know basis, for example with your Web developer for the purposes of integration with the payment gateway.
