# Charge a Tokenized Card

> How due invoices use saved Nomba card tokens for renewals.

# Charge a Tokenized Card

## In a nutshell

After the first checkout payment saves a Nomba card token, future billing cycles can be collected without asking the customer to enter card details again.

## Renewal flow

```txt theme={null}
Invoice due -> Saved card token found -> Payment attempted -> Invoice paid or failed -> Webhook sent
```

## Success behavior

When a renewal charge succeeds:

* The invoice becomes `paid`.
* The subscription advances to the next billing cycle.
* Merchant webhooks such as `invoice.paid` are sent.
* Customer payment emails may be sent.

## Failure behavior

When a renewal charge fails:

* The invoice becomes `failed`.
* The subscription becomes `paused`.
* Merchant webhooks such as `invoice.payment_failed` and `subscription.paused` are sent.
