I configured Accept and payments are not being processed. Can you help?
Double-check your credentials to make sure that you are using the API Login ID and Transaction key. Also, make sure that there is no extra spacing before or after the credentials in the payment methods page of Event Espresso.

When I go to pay with Accept, I see this error message “The payment processor appears to not be responding. Their server may be having issues, or {My Site’s Name} may have content being served over HTTP and your browser is preventing the page from loading completely. Please contact the site owner and try again using a different browser.”. What can I do to get rid of it?

First, make sure your entire site is served over https, not http.

If that doesn’t help, try this. The Accept gateway uses an invisible iframe that points to {yoursite}/wp-content/plugins/eea-authnet-accept/iframe-communicator.php. If you’re receiving that error, it’s probably because that page cannot be opened in an iframe using your browser.

You should first check you have no security plugins preventing pages from your site from being put in an iframe (ie, try disabling other plugins to see if that resolves the issue). Next, you may need to talk with your host to ask them to allow the iframe communicator page ({yoursite}/wp-content/plugins/eea-authnet-accept/iframe-communicator.php) to be placed in an iframe. This may involve changing the HTTP headers X-Frame-Options and Content-Security-Policy.

I see a message in the payment details about the payment being success but not being verified. How do I resolve this?
You can correct this issue by enabling the Transaction Reporting API through your account.

How can I set up a recurring payment or subscription through Accept?
Recurring or subscription payments are not currently supported in the Accept payment gateway.

When I refund a payment, does it also refund through Accept?
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 account and process the refund.

Is an SSL certificate needed for Accept?
A dedicated SSL certificate is required to use the Accept payment gateway.

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. Event Espresso helps by using Accept’s iframe option for payment processing.
