# Update Business Travel

> Update an existing business travel record

# Update Business Travel

Update an existing business travel record. Only provide the fields you want to change. Emissions will be recalculated automatically if relevant fields are modified.

<Warning>
  Even though all fields are individually optional, you must always provide either `distance_km` OR both `origin` and `destination` in every update request — the distance validation runs on every call.
</Warning>

<Note>
  When updating fields that affect emissions (distance, transport type, travel number, travel type), the `co2e` value will be recalculated asynchronously. The status may temporarily change to `pending`.

## 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"}
```

### 404 Not Found

**Cause:** Business travel not found or doesn't belong to your organization

```json theme={"theme":{"light":"github-light","dark":"github-dark"}}
{"detail": "BusinessTravel with id=550e8400-e29b-41d4-a716-446655440000 not found", "code": "BUSINESS_TRAVEL_NOT_FOUND"}
```

### 422 Unprocessable Entity

**Cause:** Missing distance — 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:** 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"
    }
  ]
}
```

## Use Cases

### Change Route with Distance Recalculation

Update origin and destination to recalculate distance:

```python theme={"theme":{"light":"github-light","dark":"github-dark"}}
response = requests.patch(
    f"https://api.dcycle.io/v1/business-travels/{travel_id}",
    headers=headers,
    json={
        "origin": "Paris, France",
        "destination": "Berlin, Germany",
    },
)
```

### Switch to Round Trip

```python theme={"theme":{"light":"github-light","dark":"github-dark"}}
response = requests.patch(
    f"https://api.dcycle.io/v1/business-travels/{travel_id}",
    headers=headers,
    json={
        "travel_type": "round",
        "origin": "Madrid, Spain",
        "destination": "Barcelona, Spain",
    },
)
```

### Update Car Details

```python theme={"theme":{"light":"github-light","dark":"github-dark"}}
response = requests.patch(
    f"https://api.dcycle.io/v1/business-travels/{travel_id}",
    headers=headers,
    json={
        "vehicle_size": "large",
        "fuel_type": "hybrid",
        "distance_km": 350.0,
    },
)
```
