# Send the verification email to the primary email

`POST /v1/users/{user_id}:send-verification-email` · permission `user-credentials:write`

Sends the verification email to the user's primary email. The response carries the expiry of the verification request; no code or link is returned. To target a specific email row use [Send the verification email to an email address](/docs/api/management/users/send-email-verification). The optional body only selects the email language.

## Request

| Parameter | In | Required | Description |
|---|---|---|---|
| `user_id` | path | yes | User id, prefixed `usr_`. |

Optional body:

| Field | Type | Required | Description |
|---|---|---|---|
| `locale` | string | no | BCP 47 language tag of the email, for example `tr` or `pt-BR`. Defaults to the user's or the environment's language. |

## Response

`200 OK`. `expires_at` is when the verification request expires.

```json
{
  "expires_at": "2026-01-16T09:30:00Z"
}
```

| 404 | `not_found` | The user does not exist in this environment (or the id is malformed). |
| 401 | `unauthenticated` | The API key is missing, invalid or revoked. |
| 403 | `insufficient_permissions` | The key lacks the `user-credentials:write` permission. |
| 429 | `rate_limited` | The API rate limit or the per-user email sending limit was exceeded; honor `Retry-After`. |
