Can I process a refund for a transaction using the agent?

Yes! Use the `refund_transaction` tool with the Bolt reference ID and the amount in cents. Your agent will initiate the credit transaction in your Bolt account.

How do I check the status of a specific Bolt transaction?

Simply ask the agent to `get_transaction` and provide the reference ID. It will retrieve the latest status, such as 'Authorized', 'Completed', or 'Failed', directly from Bolt.

Can I use this to generate a checkout session token?

Yes. Use the `create_order_token` tool and provide the cart details in JSON format. This will return a token that can be used on your frontend to open the Bolt checkout modal.
