Updates the merchant account's own settings: the fields named in `update_mask`.

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

## Request

| Field | Type | What it is |
| --- | --- | --- |
| `merchant_account` | `MerchantAccount` | The merchant account with its new values; `name` selects it. Required. |
| `update_mask` | `field_mask` | The fields to change. |

### MerchantAccount

| Field | Type | What it is |
| --- | --- | --- |
| `name` | `string` | `orgs/{org}/projects/{project}/envs/{env}/merchant_accounts/{merchant_account}`; the environment's seller is `default`. |
| `meta` | `ResourceMeta` | Resource metadata. |
| `automatic_tax` | `bool` | Whether Stripe computes tax on this merchant's checkouts and usage invoices (its own cost decision: Stripe Tax charges per transaction). Off by default. Writable through `UpdateMerchantAccount` (`update_mask = "automatic_tax"`). Turning it on is refused while a live `post_tax_settlement` credit grant exists. |

### 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. |

## Response

| Field | Type | What it is |
| --- | --- | --- |
| `name` | `string` | `orgs/{org}/projects/{project}/envs/{env}/merchant_accounts/{merchant_account}`; the environment's seller is `default`. |
| `uid` | `string` | `mac_<cell><ulid>`; never reused. Output only. |
| `meta` | `ResourceMeta` | Resource metadata. |
| `processor` | `string` | The processor: `stripe`. Output only. |
| `account_id` | `string` | The connected account id, for example `acct_1Nv…`. Output only. |
| `livemode` | `bool` | Whether the connection is in live mode (false is test mode). Output only. |
| `state` | `string` | `connected` or `disconnected`. Output only. |
| `charges_enabled` | `bool` | Whether the account can take payments now. Output only. |
| `payouts_enabled` | `bool` | Whether the account can be paid out. Output only. |
| `business_name` | `string` | The business name the processor holds for the account. Output only. |
| `region_code` | `string` | ISO 3166-1 alpha-2 country of the account. Output only. |
| `default_currency_code` | `string` | ISO 4217 default currency of the account, upper case. Output only. |
| `refresh_time` | `timestamp` | When the processor last confirmed these fields. Output only. |
| `credential` | `string` | How the account is called at the processor: `connect` (the platform's key acts for a connected account) or `restricted_key` (the account's own key, held sealed). Output only. |
| `automatic_tax` | `bool` | Whether Stripe computes tax on this merchant's checkouts and usage invoices (its own cost decision: Stripe Tax charges per transaction). Off by default. Writable through `UpdateMerchantAccount` (`update_mask = "automatic_tax"`). Turning it on is refused while a live `post_tax_settlement` credit grant exists. |

### 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. |
