Can my agent update the inventory levels in GrazeCart?

Yes. Use the 'update_inventory' tool. By passing the Product ID and the inventory update payload, the agent can programmatically adjust stock counts for your variants to prevent overselling fresh products.

How do I process pending payments for orders via chat?

You can use the 'charge_order' tool. Simply provide the Order ID, and the agent will trigger the payment charge request through GrazeCart's billing engine flawlessly.

Can I list active pickup locations for logistics planning through the agent?

Absolutely. Use the 'list_pickup_locations' tool. Your agent will retrieve a full list of configured pickup points, helping you organize your delivery routes or assist customers with pickup inquiries natively.
