How can I see all my pending orders?

Use the `search_orders` tool with status set to 'paid' or 'handling'. It will return a list of orders ready to be shipped.

How do I update the tracking number for a shipment?

Use the `set_tracking` action with the Order ID, Shipment ID, Carrier ID, and the Tracking Number.

Yes, use `cancel_order`. Be aware that cancelling orders can negatively impact your seller reputation metrics.

Can I register an invoice (Nota Fiscal) for a shipment?

Absolutely. Use the `register_invoice` tool with the shipment ID, invoice number (NF-e key), and access key. This is required for sellers in Brazil to comply with tax regulations.
