Can I process a refund for a payment ID through the agent?

Yes! Use the `refund_checkout_payment` tool with the payment ID. You can also specify an optional amount in minor units for a partial refund. The agent will trigger the refund process in Checkout.com immediately.

How do I see the full history of actions for a payment?

Use the `list_payment_actions` tool with the unique payment ID. Your agent will fetch all lifecycle events, such as Authorization, Capture, and Refund, along with their timestamps.

Where do I find my API Prefix?

The API Prefix is the first 8 characters of your client_id (excluding the cli_ prefix). You can also find it in your Checkout.com Hub under Developers -> API Keys.
