Hello,
We are experiencing an issue with Apple Pay integration in our application. We are using WKWebView to handle various payment methods, but we are unable to complete payments via Apple Pay.
Upon debugging the WKWebView, we received the following error message: "400 No required SSL certificate was sent" when attempting to process the payment.
Currently, we are using a Let's Encrypt SSL certificate. Could you please confirm whether this certificate is suitable for Apple Pay, or if we should be using a different SSL certificate?
