# Create a trip

> Creates a trip owned by the key's owner: blank, from a trip template (`templateId`, which brings the template's design and blocks), or from a `design` (a route: origin, stops with nights, transfers), which builds one itinerary day per trip day and derives `endDate`.

`POST /v1/trips`

Creates a trip owned by the key's owner: blank, from a trip template (`templateId`, which brings the template's design and blocks), or from a `design` (a route: origin, stops with nights, transfers), which builds one itinerary day per trip day and derives `endDate`. A design needs `startDate`. Optional `travelers`, `ownerId`, `presentation`, `profile` and `metadata` are set in the same change. With `?dryRun=true` nothing is written and a `trip_create_preview` comes back.

**Permissions:** `trips:write` · **Kind:** write · **Cost:** 1 unit · **Dry run:** `?dryRun=true` · MCP tool [`create_trip`](https://api.bymundi.com/docs/mcp/tools/create_trip.md)
