Search the Diaspark customer list (terminal/terminal/list_customers_all). All fields are optional filters; leave a field out to not filter on it.

Run the Diaspark sales receipt / item sales history report (pos/point_of_sale_report/sales_receipt_with_item_report). Dates use YYYY/MM/DD format. Use raw_overrides for any of the report's other criteria fields (str1-str60, all1-all30, multiselect1-30, dec1-10, list1-10, etc).

Run the Diaspark on-hand-by-style inventory report (inventory/inventory_report/on_hand_report_by_style). Friendly filter fields (sku, serial, brand, category, vendor, store, location, department, subcategory, group, group_code, classification, collection, designer, vendor_style, rmsa, upc) each do an exact-match filter when provided. Use raw_overrides for anything else (e.g. the all1-all30 'select all' toggle flags, date ranges, or multiselect fields) - see the report's column definitions for the full str#/all# field mapping.
