Can I record a new usage event for a customer?

Yes! Use the `add_cheddar_charge` tool with the customer code, charge code (tracked item), and quantity. The agent will record the usage in Cheddar immediately.

How do I see the billing history for a specific person?

Use the `get_cheddar_customer_details` tool with the unique customer code. Your agent will fetch the full record, including active plans, status, and associated invoices.

Where do I find my Product Secret and Product Code?

Log in to your Cheddar dashboard and look for 'Product Settings'. You can view and copy your unique Product Code and generate a Secret Key from there.
