# Create Business Travel

> Create a new business travel record for emissions tracking

# Create Business Travel

Create a new business travel record in your organization. The system will automatically calculate CO2e emissions based on the transport type and distance.

<Note>
  **Distance Options**: You can provide either `distance_km` directly OR provide `origin` and `destination` addresses to have the distance calculated automatically.
</Note>

## Common Errors

### 401 Unauthorized

**Cause:** Missing or invalid API key

```json theme={"theme":{"light":"github-light","dark":"github-dark"}}
{"detail": "Invalid API key for organization", "code": "INVALID_API_KEY"}
```

### 403 Forbidden

**Cause:** The authenticated user is not a member of the organization

```json theme={"theme":{"light":"github-light","dark":"github-dark"}}
{"detail": "Logged User is not Member of Organization", "code": "LOGGED_USER_NOT_MEMBER"}
```

### 422 Unprocessable Entity

**Cause:** Missing required fields — must provide either `distance_km` OR both `origin` and `destination`

```json theme={"theme":{"light":"github-light","dark":"github-dark"}}
{
  "detail": [
    {
      "loc": ["body"],
      "msg": "Either distance_km or origin+destination must be provided",
      "type": "value_error"
    }
  ]
}
```

**Cause:** Missing `vehicle_size` or `fuel_type` when `transport_type` is `car`

```json theme={"theme":{"light":"github-light","dark":"github-dark"}}
{
  "detail": [
    {
      "loc": ["body"],
      "msg": "vehicle_size is required for car transport",
      "type": "value_error"
    }
  ]
}
```

**Cause:** `end_date` is before `start_date`

```json theme={"theme":{"light":"github-light","dark":"github-dark"}}
{
  "detail": [
    {
      "loc": ["body", "end_date"],
      "msg": "end_date must be on or after start_date",
      "type": "value_error"
    }
  ]
}
```

**Cause:** Unknown field sent in request body (this endpoint rejects extra fields)

```json theme={"theme":{"light":"github-light","dark":"github-dark"}}
{
  "detail": [
    {
      "loc": ["body", "round_trip"],
      "msg": "extra fields not permitted",
      "type": "value_error.extra"
    }
  ]
}
```

## Validation Rules

1. **Distance Input**: Provide either `distance_km` OR both `origin` and `destination`
2. **Date Range**: `end_date` must be on or after `start_date`
3. **Travel Number**: 1 to 10,000, further limited to max 100 per day in the date range
4. **Car Transport**: `vehicle_size` and `fuel_type` are required when `transport_type` is `car`
5. **Vehicle Size Restriction**: `vehicle_size` is only allowed for `car` transport
6. **Extra Fields**: This endpoint rejects any fields not listed above (e.g. `flight_type`, `cabin_class`, `round_trip`)
