MarketMan Inventory & Items API

info:
  title: MarketMan API V3
  description: >-
    MarketMan provides a JSON REST API for integration with third-party
    applications such as accounting, ERP, e-commerce, and self-service portals.
    The V3 API exposes separate Buyer and Vendor surfaces for inventory, items,
    vendors, purchase orders, invoices/docs, deliveries, recipes/menu costing,
    POS sales, and webhooks. All operations are HTTP POST that accept and return
    JSON. Authentication is token-based: call /v3/buyers/auth/GetToken (or the
    vendor equivalent) with an APIKey and APIPassword to obtain a Token, then
    send that token on every subsequent request in the AUTH_TOKEN header.
    Endpoints, request fields, and response shapes here reflect the publicly
    published MarketMan API V3 Postman documentation; field-level detail not
    documented publicly is left unconstrained.
