How do I find my Afterpay Merchant credentials?

Log in to your Afterpay Merchant Portal, go to **Settings** > **API**. You can generate and retrieve your **Merchant ID** and **Secret Key** there. Make sure to choose the correct region (US, AU, UK).

Can I process a partial refund via the agent?

Yes! Use the `refund_payment` tool and provide the `orderId` and the specific amount. Your agent will submit the partial refund request to Afterpay for processing.

What is the difference between Capture and Auth?

'Capture' finalizes the payment immediately. 'Auth' (Authorization) holds the funds on the customer's account, and you must call the capture tool later (usually when shipping) to finalize the transaction.
