  • Added sales_tax_amount shortcode attribute to plugin. This may help qualification rate. Contact Clearent customer support for questions or more information.
  • Updated plugin so that payments form will not be built (errors will be shown on page) if invalid shortcode attributes are set. This insures that you don't think you are setting something when in fact you are not.


  • Fixed issue where amount could be interpreted wrong. Letting the server handle all validations of valid amount.
  • Added failed transactions to the transaction log to help merchants help their customers easier. Added detailed transaction status from server.
  • Cleaned up address display in transaction log.
  • Updated this changelog so most recent changes show first (reverse chronological).
