# Update an Opportunity Custom Field

`PUT /custom_field/opportunity/{id}/`

You can rename it, change its type, change whether it accepts multiple values or not, change whether editing its values is restricted to specific Roles, or update the options for a "choices" field type. The updated name will immediately appear in the Close UI and only valid values for the updated `type` will be returned by the Contact API.

Some of the type changes need to convert all of the existing values for a given Custom Field to the new type. When this is required, the response will include an additional `converting_to_type` field. When the conversion is done, `converting_to_type` will no longer be returned.

## Path parameters

- `id` string, required

## Response `200`

Successful response

## Other responses

- `400` — Bad request
- `401` — Unauthorized
- `404` — Not found
