Updates the environment's checkout policy, whole.

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

## Request

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

### CheckoutPolicy

| Field | Type | What it is |
| --- | --- | --- |
| `name` | `string` | `orgs/{org}/projects/{project}/envs/{env}/checkout_policies/default`. |
| `meta` | `ResourceMeta` | Resource metadata. |
| `spec` | `CheckoutPolicySpec` | 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. |

### CheckoutPolicySpec

| Field | Type | What it is |
| --- | --- | --- |
| `denied_country_codes` | `string[]` | Buyer countries consumer checkout refuses: ISO 3166-1 alpha-2 codes (`DE`), or the group `EU` (the 27 member states). At most 300 entries. Empty refuses nobody. |
| `allow_tax_id_buyers` | `bool` | Whether a buyer from a denied country who gives a tax id (a business) may still buy. Checkout then asks for the tax id; default false. |

## Response

| Field | Type | What it is |
| --- | --- | --- |
| `name` | `string` | `orgs/{org}/projects/{project}/envs/{env}/checkout_policies/default`. |
| `uid` | `string` | `cpl_<cell><ulid>`; never reused. Output only. |
| `meta` | `ResourceMeta` | Resource metadata. |
| `spec` | `CheckoutPolicySpec` | Desired state. Required. |

### ResourceMeta

| Field | Type | What it is |
| --- | --- | --- |
| `generation` | `int64` | Increases by one on every change to `spec`. Output only. |
| `etag` | `string` | Strong ETag (AIP-154): changes on any change to spec, status, or metadata. Send it back as `If-Match` or `etag` to make Update and Delete conditional; a mismatch fails with ABORTED / 409 `ETAG_MISMATCH`. Output only. |
| `create_time` | `timestamp` | When the Resource was created. Output only. |
| `update_time` | `timestamp` | When the Resource last changed. Output only. |
| `delete_time` | `timestamp` | Set while the Resource is being deleted. Output only. |
| `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. |
| `creator` | `string` | The principal that created the Resource. Output only. |

### CheckoutPolicySpec

| Field | Type | What it is |
| --- | --- | --- |
| `denied_country_codes` | `string[]` | Buyer countries consumer checkout refuses: ISO 3166-1 alpha-2 codes (`DE`), or the group `EU` (the 27 member states). At most 300 entries. Empty refuses nobody. |
| `allow_tax_id_buyers` | `bool` | Whether a buyer from a denied country who gives a tax id (a business) may still buy. Checkout then asks for the tax id; default false. |
