hi! if you're integrating that way, you need to upload your Apple Pay processing certificate to your Stripe account, which it doesn't appear you've done, looking at the account associated with that request ID

https://stripe.com/docs/apple-pay?platform=ios#csr

needs to be uploaded at https://dashboard.stripe.com/settings/payments/apple_pay under the 'iOS certificates' section, the Add New Application section walks you through it.

The domain part is not relevant if you integrate this way I think. You're not actually doing Stripe+Apple Pay on the Web in this context if for whatever reason you're sending us a PkPayment, so it works like a native payment. Curious why you're integrating this way and not using stripe.js normally.
