Lavu (POSLavu) API
A POST-based data API for the Lavu restaurant POS. A single request server accepts form-encoded dataname, key, token, and table parameters and returns XML rows; reads support column/value exact-match filters, value_min/value_max range filters, and limit (offset,count) pagination, while cmd=insert writes XML row payloads. Documented tables include menu_groups, menu_categories, menu_items, tables, orders, order_contents, order_payments, ingredients, and ingredient_usage. Credentials come from the API tab of the POSLavu Control Panel.
