# Update White-label Config

`PATCH https://api.astroway.info/v1/whitelabel/config`

Update one or more branding fields. Hex colours validated as #RRGGBB; custom_domain validated as RFC-1035 subdomain. Setting custom_domain resets domain_verified=false; call /whitelabel/domain/verify after pointing your CNAME to api.astroway.info.

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

## 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. |

| `primaryColor` | string | no |  |
| `secondaryColor` | string | no |  |
