What an iTeam agent does with the Tiny ERP API
Late order, customer informed
The agent finds orders stuck in picking or without an invoice and alerts shipping and the customer.
Low stock by channel
The agent compares sales and stock and sends the buyer the list of products to reorder.
Invoice on demand
The customer asks for the invoice on WhatsApp, and the agent finds the order's file and sends it.
Catalog check
Products with no NCM (tax classification code), weight or image are listed before they go to the marketplaces.

Store it in the iTeam vault
The credential stays in the vault. Lookups are open, while issuing invoices or changing status require approval at the start.
Validate with real orders in read mode
Start by reading orders and inventory, and only then enable writing gradually.
