What will be the method for setup Apple pay?

[jabirabbas]

As per your description : If in your catch you get the message This device can make payments but has no supported cards - you can decide if you want to handle this by showing the 'Setup Apple Pay' buttons instead of the normal 'Pay with Apple Bay' buttons as per the Apple Guidelines.

So what method can be invoked for let user set the apple pay? Please help.

Thanks
