The client SDKs tokenise card details into a payment method nonce, a one-time reference the server passes to a sale or to the vault. A nonce can be consumed exactly once and expires unused after roughly three hours. Reusing one returns a validation error saying the nonce was not found or has already been consumed, which is precisely what happens when a retry after a network timeout resends the original request body.
Storing a nonce to charge later does not work. The durable equivalent is a vaulted payment method token, obtained by vaulting on success during the sale or by creating a payment method for a customer. Confirm by submitting the same nonce twice in the sandbox. Retry by re-tokenising in the client, never by replaying the nonce server side.
