  title: Navan Bookings Fees and Adjustments API
  description: 'The Navan API is the public developer surface for the Navan (formerly TripActions) corporate travel, expense, and corporate card platform. It is a REST/HTTPS API secured with OAuth 2.0 using the client-credentials grant. Administrators generate a client_id / client_secret in the Navan app under Settings > Integrations (API), exchange them for a Bearer access token, and call the API with `Authorization: Bearer <token>`. Access is scoped (e.g. bookings:read, users:read, users:write, users:delete, and the expense read/write scopes).


    Endpoint status: the Expense API paths (transactions, fees, adjustments, receipts, custom fields) and the travel/v1 Users paths are CONFIRMED against Navan''s published API reference and third-party integration guides. The Bookings and Webhook subscription-management paths are MODELED - the relevant scopes and capabilities are documented by Navan, but the exact request paths are behind a gated reference and are represented here as a best-effort model. Modeled operations are flagged with `x-endpoint-status: modeled`.'

  x-rebrand-note: Navan was known as TripActions until its February 2022 rebrand to Navan; some legacy hostnames and token paths still carry a `ta-` (TripActions) prefix, e.g. the `ta-auth` OAuth token path.
