  title: Fyle Platform Advances Expenses API
  description: 'The Fyle Platform API (Fyle is now Sage Expense Management) exposes the objects behind Fyle''s spend and expense management product - expenses, expense reports, advances, categories, projects, cost centers, employees, merchants, corporate cards and their real-time transactions, files/receipts, and webhook subscriptions - as role-scoped REST resources. Every path is served under a role segment (admin, spender, approver, or common); this document models the admin, spender, and common surfaces most commonly used for accounting/HRMS integration.


    Authentication is OAuth 2.0 using the refresh-token grant: exchange a long-lived refresh token (with client_id and client_secret) at the token endpoint for a short-lived Bearer access token, then send it as `Authorization: Bearer <access_token>`.


    List endpoints follow a PostgREST-style convention: `offset`, `limit`, and `order` query parameters are mandatory, and any response field can be filtered with operators like `id=eq.<uuid>` or `updated_at=gte.<timestamp>`. A single resource is fetched by filtering on its id.


    Endpoint paths and HTTP verbs in this document are grounded in Fyle''s open-source Python Platform SDK (github.com/fylein/fyle-platform-sdk-py). Request and response object field shapes are modeled representatively - consult the live Stoplight reference at docs.fylehq.com for exhaustive schemas.'
