Before you connect

Questions about Highnote.

The practical details behind the request, access and result.

Can I use the Highnote MCP to freeze lost cards?

Yes, you can tell your agent to freeze a card immediately. It will update the status in Highnote so the card can't be used for new transactions.

How does the Highnote MCP help with financial audits?

It allows your agent to pull individual ledger entries for any account. This makes it much faster to verify specific transactions against your records.

Can my agent see the balances of all my accounts?

Yes, you can ask your agent to list all financial accounts. It will return a list of your accounts and their current balances in one go.

Does the Highnote MCP work for both virtual and physical cards?

It works for both. You can use it to monitor the status and details of any card issued in your program.

Can I use this to see merchant details for transactions?

Yes, your agent can pull specific metadata for transactions. This includes information about where the money was spent and the merchant's details.

Is the Highnote MCP good for neobanks?

It's ideal for neobanks because it gives support teams a way to check card statuses and balances instantly during customer calls.

How do I find my Highnote API Key?

Log in to your Highnote dashboard, navigate to Settings > API, and you will be able to generate and copy your API key. Make sure to distinguish between Test and Live keys based on your environment.

What environments are supported?

The integration supports both the Test (Sandbox) and Live (Production) environments. You must specify which one you are connecting to during setup to ensure the correct API endpoints are used.

Can I freeze a card through this integration?

Yes! Use the update_card_status capability and set the status to FROZEN. This will immediately prevent any new authorizations on that card. You can set it back to ACTIVE to unfreeze it.

Is the integration secure for financial data?

Absolutely. The integration uses industry-standard Basic Authentication over HTTPS. Your credentials and financial data are encrypted and stored securely within the Vinkius Cloud infrastructure.
