Use of the Bank of America Gateway through either the Microform Integration or Card Not Present Toolkit integration method requires a Shared Secret key. 

You can generate a security key for use in a live payment processing environment, or you can first generate a security key for testing in the DCE. When you are ready to begin processing live payments, generate a new key within your online banking Merchant Services account.

To generate a Shared Secret key

  1. Log in to your desired environment: 
  2. From the left navigation, select Payment Acceptance Configuration > Key Management.
  3. Click Generate Key in the top right corner.
