Can I automatically refund payments without ever navigating to the Clip website?

Yes. The `refund_transaction` interface executes server-side cryptographic voiding. Pass the definitive transaction ID alongside an optional amount override, and the refund logic routes directly through Clip's banking partners unconditionally.

Are the payment links generated permanent or do they have expiration windows?

By default, Payment links created via this endpoint remain actively valid until either paid successfully or explicitly halted. You can seamlessly use the `cancel_payment_link` tool to kill rogue links manually blocking external vulnerability loopholes.

Can the agent check if physical POS terminals are active and connected to my account?

Yes. The `list_terminals` endpoint fetches the fleet array directly from Clip servers. It outputs device IDs mapped to your registry ensuring no unauthorized POS physical readers are leeching payments stealthily.
