Right now, I'm using the sqPaymentForm object, embedded in my application. I receive a nonce, authorize and capture a transaction. Once that passes correctly, I want to persist that nonce in a reusable payment_method but I always get the CARD_TOKEN_USED error.
I assume that nonce can therefore only be used once.
Do I absolutely need to create the customer and card before the charge? This is contrary to how I use the other payment gateways I've integrated with. The issue is I don't want to save a payment method before I confirm the payment has at least been preauthorized.
