Updates a catalog.

- **Path** `PATCH https://api.sylphx.com/v1/orgs/acme/projects/shop/envs/production/catalogs/catalog`
- **Scope** `localization:write`
- **Effect** `write` — a successful call changes state.
- **Collection** [catalogs](/docs/api/catalogs)
- **Query** `update_mask`, `allow_missing`, `validate_only`

## Request

| Field | Type | What it is |
| --- | --- | --- |
| `catalog` | `Catalog` | The catalog to update; `name` identifies it. Required. |
| `update_mask` | `field_mask` | The fields to write; unset writes every populated field. |
| `allow_missing` | `bool` | Create the catalog when it does not exist (declarative upsert). |
| `validate_only` | `bool` | Validate and return the result without writing anything. |

### Catalog

| Field | Type | What it is |
| --- | --- | --- |
| `name` | `string` | `orgs/{org}/projects/{project}/envs/{env}/catalogs/{catalog}`. |
| `meta` | `ResourceMeta` | Resource metadata. |
| `spec` | `CatalogSpec` | Desired state. Required. |

### ResourceMeta

| Field | Type | What it is |
| --- | --- | --- |
| `labels` | `map<string, string>` | Caller-writable, indexed labels (AIP-122 label rules). |
| `annotations` | `map<string, string>` | Caller-writable, unindexed annotations. |
| `display_name` | `string` | Caller-writable human-readable name. |

### CatalogSpec

| Field | Type | What it is |
| --- | --- | --- |
| `source_locale` | `string` | The locale the source texts are written in, a BCP 47 tag such as `en`. Required. |
| `target_locales` | `string[]` | The locales to translate into, BCP 47 tags. `zh-Hant-HK` and `zh-Hant-TW` are separate locales. At most 60, each once. |
| `pseudo_locales` | `PseudoLocale[]` | Pseudo-locales to generate at export. They are never stored or translated. One of `accented`, `bidi`, `wide`. |
| `tone` | `string` | The brand voice every translation follows, at most 2000 characters. |
| `locale_guidance` | `map<string, string>` | Extra instructions per target locale, for example the vocabulary of a region. Keys are target locales; at most 60 entries, each at most 2000 characters. |
| `glossaries` | `string[]` | The glossaries this catalog applies, as Glossary names; at most 10. |

## Response

| Field | Type | What it is |

| `create_time` | `timestamp` | When the Resource was created. Output only. |
| `update_time` | `timestamp` | When the Resource last changed. Output only. |
