  title: Fulfil REST API (v2)
  description: >-
    Fulfil is a cloud ERP and operations platform for e-commerce, DTC, and
    wholesale merchants. Its REST API (v2) exposes every ERP resource through a
    single, uniform "model interface": each business object (sales orders,
    products, stock moves, parties, shipments, purchases, production, and
    thousands more) is a named model addressed at
    `/api/v2/model/{model.name}`, with generic CRUD, a `search_read` search,
    `count`, and the ability to call arbitrary model methods (actions), run
    reports, and drive wizards. Fulfil advertises 6,000+ endpoints across all
    models.

    The base URL is per-merchant: `https://{merchant_id}.fulfil.io/api/v2`.
    Authentication is either a personal access token sent in the `X-API-KEY`
    header (or as HTTP Basic) for private integrations, or OAuth 2.0 for public
    apps. Use `GET /api/v2/test` to verify credentials.

    Fulfil records are model-specific and dynamically typed, so request and
    response bodies below are represented as open JSON objects (a `Record` is
    an object with an integer `id` plus arbitrary model fields). This document
    models the generic interface plus concrete headline models; the same
    interface applies to any other Fulfil model by substituting its name.
