# Preview White-label Report

`POST https://api.astroway.info/v1/whitelabel/preview`

Render a sample natal report PDF using the authenticated user's white-label configuration (colours, font, footer, logo). Pass `chart` to use your own birth data; omit to use the bundled Kyiv 1990 sample.

Group: White-label. Auth: `X-Api-Key` header. Operation ID: `whitelabel_preview`.

## Parameters

| Name | In | Required | Type | Description |
|---|---|---|---|---|
| `fields` | query | no | string | Comma-separated dotted paths, relative to `data`, to keep in the response. A path is applied to every element of an array, so `planets.name` means the name of each planet. Paths that match nothing come back in `_fields_unmatched`; a list where nothing matches at all is a 400, because an empty object would be a confident wrong answer. |
| `precision` | query | no | integer | Round every non-integer number in the response to this many decimal places. Integers are left alone, because an id is not a measurement. Ecliptic longitudes ship with fourteen decimals by default; 2 is about a tenth of an arcminute. |

## Request body

| Field | Type | Required | Description |
|---|---|---|---|
| `chart` | object | no |  |
| `language` | "uk" \| "en" \| "de" \| "ru" \| "pl" \| "es" \| "pt" \| "hi" \| … | no |  |

```json
{
  "language": "uk"
}
```

## Responses

| Status | Meaning |
