Troubleshooting

I configured Authorizenet AIM and payments are not being processed. Can you help?
Double-check that you are using your API credentials for production (live) mode which are different than your login information for your Authorize.net account. Also, ensure that there is no extra spacing before or after the credentials in the payment methods screen of Event Espresso 4.

When I refund a payment, does it also refund through Authorize.net?
Refunds in Event Espresso 4 are currently a two-step process.
1) Apply the refund through the transactional details screen of Event Espresso in your WP-admin (WP dashboard).
2) Then login to your Authorize.net account and process the refund.

Recurring or subscription payments are not currently supported in the Authorize.net AIM payment gateway.

PCI Compliance Notes

Is an SSL certificate needed for Authorize.net AIM?
A dedicated SSL certificate is recommended if you are accepting payments on your website.

Are full credit card numbers stored in the website’s database?
No. Event Espresso records only the last four digits.

Do I need to be PCI compliant?
Compliance with the Payment Card Industry Data Security Standards (PCI DSS) is required if you are processing, storing, or transmitting credit card data. Since the card info is transiting your server when you use an onsite payment method like Authorize.net AIM Event Espresso recommends using a dedicated SSL certificate on your website, and setting the entire site to load as https.
