Hello,
I', are trying to add applepay payment on our website using the PSP payxpert. They don't provide any SDK to my knowledge unlike paypal/stripe and their documentation just tell to send a few different data as usual credit card payment.
But I'm stuck even before that step, we were able to add the applepay button on the site, we did setup the sandbox account on the iPhone with a test card.
We could add the merchant id, created the "Apple Pay Payment Processing Certificate", the "Apple Pay Merchant Identity Certificate" and we verified the marchant domain.
We have our backend request the validationURL on onvalidatemerchant. We're using PHP, and send the data in json as the example in:
https://developer.apple.com/documentation/ApplePayontheWeb/requesting-an-apple-pay-payment-session
The validation url we receive from applepaysession js is: https://apple-pay-gateway-cert.apple.com/paymentservices/startSession
The doc mentions to add /paymentSession so I tried that as well as just the raw validationURL. Both sends me a 401 Unauthorized response.
I'm not sure what missing, I double checked the merchantIdentifier matches and that the initiativeContext is correct, but no luck.
I wonder if we missed a step in the configuring the server, as it say to create certificate and upload them. Then we can download the .cer files, do we need to do something with that?
Kind regards
