Hi,
To add your AppleCard to ApplePay, you'll need to follow the steps outlined here:
"How to add a debit or credit card on your iPhone
- In the Wallet app, tap the Add button
.
- Tap Debit or Credit Card to add a new card.
- Tap Previous Cards to add a card that you used previously.
- Tap Continue.
- Follow the steps on the screen to add a new card.
- Verify your information with your bank or card issuer. They might ask you to provide more information or to download an app before approving your card for use with Apple Pay.
- If you have a paired Apple Watch, you have the option to also add the card to your watch.

If you're trying those steps and are having issues, we'll need to know exactly what happens when you attempt to add it this way, including any error messages or similar.
Cheers.
