hi! what's the customer ID and what exact code are you using?

but the short answer is that you need to use a different endpoint, /v1/payment_methods. https://stripe.com/docs/api/payment_methods/list

this is c#

var stripeCustomer = await _stripeCustomerService.GetCustomerByAffiliateIdAsync(affiliateId);
        var service = new CardService();
        var options = new CardListOptions
        {
            Limit = 1,
        };

        var stripeCards = await service.ListAsync(stripeCustomer.Id, options, _requestOptions);
        return stripeCards.ToList();

customerID: cus_MTs1fmT5IP7WF7

yep, that customer has PaymentMethods pm_xxx, so you need to use PaymentMethodService to list their cards and other methods
