# Create option

`POST` `/api/1/taxonomy/metaproperties/{metapropertyId}/options`

Operation ID: `postApi1TaxonomyMetapropertiesMetapropertyidOptions`

Create a new option. Note: when the `name` you provide differs from the option's label, Bynder automatically assigns that `name` value as the option's `externalReference`. Explicitly setting `externalReference` to `null` or an empty string does not prevent this. To store a specific external reference, pass the desired value in the `externalReference` field.

## Path parameters

- `metapropertyId` (string, uuid, required)

## Request body (required)

Content types: `application/json`

## Responses

- `200`
- `201`
- `400`
- `404`
