After you configure your payment device to run a sale, you can also extend your integration to include the following:

- [**Capture a signature**](/guides/payments/payroc-cloud/capture-signature) - Capture a signature on a payment device.
- [**Run an unreferenced refund**](/guides/payments/payroc-cloud/run-unreferenced-refund) - Run a refund that isn't linked to a transaction.
- [**Run a referenced refund**](/guides/payments/refunds/referenced-refund-card) - Run a refund that is linked to a transaction.
- [**Reverse a transaction**](/guides/payments/refunds/void-card) - Cancel a transaction in an open batch.
