Can the AI automatically process a refund for a specific transaction ID?

Yes! Use the `create_transaction` tool with the 'refundTransaction' type. You'll need to provide the original transaction ID and the amount to be credited back to the customer.

How do I check for transactions that have not yet been settled?

Simply ask the agent to run the `get_unsettled_transaction_list` tool. It will return all transactions currently sitting in your unsettled queue for review.

Is it possible to manage customer payment profiles securely through the AI?

Yes. The `get_customer_profile` tool allows the agent to retrieve stored profiles (without exposing full sensitive card data), enabling you to manage recurring billing and saved information securely.
