## Update a valuation

`PUT https://getkollek.com/api/copies/{copy}/valuations/{valuation}`

Update a valuation, for correcting a figure that was entered wrong. Every field is replaced, so send the ones you want to keep along with the ones you are changing.

**Permissions:** Owners and editors. Viewers get a 404 response.

### Path parameters

- `copy` (integer, required): The ID of the copy the valuation belongs to.
- `valuation` (integer, required): The ID of the valuation.

### Body parameters

- `amount` (integer, required): What the copy was reckoned to be worth, in the smallest currency unit (e.g. cents).

- `confidence` (string, optional): How much weight the valuation carries. One of low, medium, high or unknown. Defaults to unknown.
