To use LicenseEngine with Zaxaa you will need to do the following:
1) Get your Zaxaa signature from the accounts settings page here. Click the Account Settings Tab and at the bottom click "Show API Signature". This will give you a string that will need to be copied into LicenseEngine.
2) In LicenseEngine, paste this value into the "Account" tab in the "Zaxxa Signature" field.
3) In Zaxaa, you will then need to paste the LicenseEngine IPN url into the field labeled "Zaxaa Payment Notification URL". (see figure 1 and 3)
