# List card payment methods

> List the payment methods available to a buyer in one country.

The methods a buyer in `country` can pay with — the `payment_method` value
[quote](/api/card/quote) and [checkout](/api/card/checkout) accept. A country
that is not served returns an empty list, which is your signal to hide the card
option for that buyer.

The list is not limited to plain cards. Where a country supports them, digital
wallets such as Apple Pay and Google Pay come back as their own rows, each with
its own `min_amount` and `max_amount`. `payment_method` is an open string and
the catalog varies by country, so render each row's `name` and pass its
`payment_method` straight back rather than matching against a fixed set.
