description: >-
Specification of the TravelPerk Open API. TravelPerk is a business-travel
management platform; its REST API exposes trips and bookings, invoices and
invoice lines, invoice profiles, cost centers, traveler/member provisioning
(SCIM 2.0), and webhooks. Requests are authenticated with an OAuth 2.0
access token (or API key) passed in the Authorization header, and an
`Api-Version` header selects the API version.
