Perplexity

Track payments in Claude Desktop

`list_checkout_payments` pulls your recent transaction history right into the chat interface. You ask your AI client for the latest failed charges, and it reads the live data directly from the gateway. Finding specific transactions takes seconds instead of minutes spent clicking through web portals. Digging deeper requires exact context. When a customer complains about a double charge, `get_payment_details` grabs the raw transaction data. Your agent reads the status, currency, and risk flags so you know exactly what went wrong before you reply to the support ticket.

Execute refunds via MCP Server

`refund_checkout_payment` sends money back to the customer without making you log into a separate system. You tell Claude to reverse a specific charge ID, and the MCP Server executes the API call immediately. Handling billing disputes becomes a simple chat command. Managing authorizations works the exact same way. If you need to clear a pending hold, `void_checkout_payment` drops it instantly. When it is time to collect the funds, `capture_checkout_payment` secures the payment.

Inspect webhooks and account data

`get_checkout_account_info` reads your merchant configuration to verify active processing regions. You can ask Claude to check if a specific sub-entity is live. Getting this data directly in your chat window saves you a trip to the developer settings page. Dropped events cause massive headaches for engineering teams. Running `list_checkout_webhooks` lets you see exactly where your payment notifications are going. You spot misconfigured endpoints immediately and fix them before they impact production.
