Description
The Authorize.net Accept addon connects the checkout of Event Espresso to Authorize.Net’s Accept API, processing event registration charges directly through the gateway and returning transaction status to the participant’s record. The integration keeps payments within the native flow of Event Espresso, recording the transaction ID on the order and updating registration status based on the approval returned by Authorize.Net.
