Isn't it possible to not process credit cards at all for DT Register and DT Donate on website, but send visitors to Authorize.net page to enter their credit card information? We would prefer not to handle cc numbers at all. I don't see any setting for this.
Thanks in advance...
No, there is no setting for this. The Authorize.net integration handles everything in your site. The credit card numbers do not get saved in your site... only processed. So you don't have to worry about storing that type of info. You SHOULD have a SSL certificate though.
