## Create an enumeration field value

`POST /v1/userfields/:entity/enum-values`

Adds one option to an existing CRM enumeration field. Send the body without a `fields` wrapper.

> **This feature is rolling out.** It requires a CRM update after `26.2200.0` and activation by an administrator. The release version has not been published. Until available, requests return `422 METHOD_NOT_YET_AVAILABLE` with `error.release`.

For Smart Process Automation (SPA) fields, use the same contract at `POST /v1/items/:entityTypeId/userfields/enum-values`. Invoices are also available through `entityTypeId=31`.

## Parameters

| Parameter | Type | Required | Default | Description |
|---|---|---|---|---|
| `entity` (path) | string | yes | — | `deals` — deals, `leads` — leads, `contacts` — contacts, `companies` — companies, `quotes` — estimates, `invoices` — invoices |
| `entityTypeId` (path) | integer | for the alternate path | — | [SPA type](/docs/entities/smart-processes/list) ID, or `31` for invoices |

## Request body fields

| Field | Type | Required | Description |
|---|---|---|---|
| `fieldId` | integer / string | yes | ID or `UF_*` code of an enumeration field. Sources: [CRM fields](/docs/userfields/crm/list), [SPA fields](/docs/userfields/smart-processes/list) |
| `value` | string | yes | Option label |
| `isDefault` | boolean | no | Use as a default option |
| `sort` | integer | no | Sort order |
| `xmlId` | string / null | no | External integration ID |
