How can I securely pass card inputs if the chat format is plain text?

The integration routes direct requests to Nuvei's sandbox or live vault using the `create_card_token` feature natively. Since the AI environment is localized and isolated by default, inputs made within Claude or Cursor are ephemeral and pass straight into Nuvei via the secure connection layer without persisting in logs.

Can I query why a specific transaction was declined?

Yes. Ask the agent to use `get_payment` with your transaction ID. The AI will parse the complex payload returned by Nuvei and summarize the error message (e.g., Insufficient Funds, Do Not Honor) directly in human language.

Is it possible to track batch settlements?

Use the `get_transactions` capability. Your prompt can specify that you want to list out the last 20 payments, and the AI will structure them neatly as a tabular view in your chat interface.
