Q: Can I issue refunds through Authorize.net using Claude Desktop?

Yes. Your agent calls the refundtransaction tool with the original transaction ID to process refunds. The desktop app executes this command securely via the Vinkius gateway.

Q: How do I handle unsettled transactions?

You run getunsettledtransactionlist to fetch the most recent pending charges. From there, you tell your agent to void or capture them as needed.

Run payment audits and customer lookups directly inside Claude Desktop without leaving your chat window.

Track Settled Batches in Claude Desktop

The `get_settled_batch_list` tool pulls transaction histories for any date range you specify. Your agent uses this MCP tool to cross-reference deposits with your internal ledger. Once you locate a batch, the `get_transaction_list` tool fetches individual records. You get raw transaction IDs and amounts without opening the Authorize.net merchant dashboard.

Look Up Customer Profiles Instantly

The `get_customer_profile` tool retrieves stored customer files using their unique IDs. Your agent reads the profile data to verify billing addresses or shipping details during support chats. If you need to find a profile but do not have the ID handy, `list_customer_profiles` returns a complete list of active profile IDs. This lets your agent scan and locate the correct account in seconds.

Resolve Payment Issues via MCP Server

The `refund_transaction` tool processes refunds for settled transactions directly from your chat input. You provide the transaction ID, and the server executes the credit back to the customer's card. For pending charges that have not settled yet, `void_transaction` cancels the transaction immediately. This stops the settlement process before the daily cutoff.
