# Enviar instrucciones de configuración de DNS por correo

> POST /custom-domain/{pk}/send-instructions/

Envía por correo electrónico las instrucciones de configuración DNS de un dominio a un destinatario, en el host de la **API de gestión** (`api.scanova.io`), autenticado con su clave de API de gestión sin procesar.

```
POST https://api.scanova.io/custom-domain/{pk}/send-instructions/
Authorization: 401f7ac837da42b97f613d789819ff93537bee6a
```

<ParamField path="pk" type="integer" required>
  El `id` del dominio, obtenido de [Listar dominios personalizados](/es/api-reference/management-api/custom-domain/list).
</ParamField>

<ParamField body="email" type="string" required>
  Dirección de correo del destinatario. No necesita pertenecer a un usuario de Scanova — está pensado para delegar la configuración a quien administre el DNS del dominio (p. ej. un equipo de TI).
</ParamField>

<ParamField body="note" type="string">
  Una nota opcional incluida en el correo, máximo 1000 caracteres.
</ParamField>

<RequestExample>
  ```bash cURL theme={null}
  curl -X POST "https://api.scanova.io/custom-domain/42/send-instructions/" \
    -H "Authorization: 401f7ac837da42b97f613d789819ff93537bee6a" \
    -H "Content-Type: application/json" \
    -d '{
      "email": "it-team@example.com",
      "note": "Please add these records before Friday."
    }'
  ```
</RequestExample>

<ResponseExample>
  ```json 200 theme={null}
  { "detail": "Setup instructions sent." }
  ```
</ResponseExample>

El correo incluye el destino CNAME y el valor de verificación TXT del dominio — los mismos valores que devuelve [Listar dominios personalizados](/es/api-reference/management-api/custom-domain/list). `404` si `pk` no es un dominio propiedad de esta cuenta.

    shared users & roles), plus the token-creation and usage-stats endpoints
    used to authenticate against it. Every path and request/response shape below
    was verified live against a real API key and the actual running backend
    (Phase 7, 2026-08-16) — not guessed from reading urls.py alone.

      description: >-
        Send your Management API key as the raw value of the Authorization
        header — no "Bearer " or "Token " prefix, and no other characters.
        Example: `Authorization: 401f7ac837da42b97f613d789819ff93537bee6a`. A
        header containing more than one space-separated part is rejected
        outright. Requests also require the request's Host header to be the
        management API host (e.g. api.scanova.io) — the same key sent to the
        regular API host will not authenticate.
