Can I process a refund for a transaction using the agent?

Yes! Use the `refund_transaction` tool with the Transaction Node ID. You can also specify a partial amount if you don't want to refund the full charge.

How do I capture a previously authorized transaction?

Simply ask the agent to `capture_transaction` and provide the Transaction Node ID. The funds will be captured and the status updated in your Braintree account.

Does the integration allow searching for a customer by email?

Yes. Use the `search_customers` tool and provide the exact email address. The agent will execute a GraphQL query to find the matching customer profile.
