Can I check the status of a specific payment transaction?

Yes! Use the `get_transaction` tool with the Transaction ID. Your agent will fetch the latest status, including whether it is 'Success', 'Pending', or 'Failed'.

How do I list all my active subscription plans?

Simply ask the agent to `list_plans`. It will retrieve all recurring billing plans configured in your BlueSnap account for you to review.

Does the integration allow processing a new refund?

Currently, the toolset is focused on querying and monitoring (Read-Only). You can list and inspect transactions, but processing refunds or charges must be done through the BlueSnap portal for financial security.
