Navan
Navan (formerly TripActions, rebranded to Navan in February 2022) is a corporate travel, expense, and corporate card management platform. Its public developer surface centers on the Navan Expense API (OAuth 2.0 client-credentials) for retrieving and updating transactions, fees, adjustments, receipts, and custom fields, plus a Travel/User Management API for provisioning users and reading booking data, and webhooks for change notifications. Navan also publishes an MCP server for connecting AI assistants to Navan data. Booking (travel) is offered at no platform cost and funded by supplier commissions and per-trip fees, while Expense is a per-user subscription.
