  title: MarketMan API V3 Accounts Authentication API
  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.'
