| `usage_tier` | `UsageTier` | The usage tier with its new values; `name` selects it. Required. |
| `update_mask` | `field_mask` | The fields to change. |

### UsageTier

| Field | Type | What it is |
| --- | --- | --- |
| `name` | `string` | `orgs/{org}/projects/{project}/envs/{env}/usage_tiers/{usage_tier}`; the id is the tier key. |
| `meta` | `ResourceMeta` | Resource metadata. |
| `rank` | `int32` | Order of tiers; 0 is the base tier. Required. |
| `daily_limit_minor` | `string` | Daily exposure limit in minor units, a decimal string; empty for none. |
| `monthly_limit_minor` | `string` | Monthly exposure limit in minor units, a decimal string; empty for none. |
| `threshold_minor` | `string` | The amount an invoice would make due at which a threshold invoice is cut. Required. |
| `requires_paid_invoices` | `int32` | Paid invoices needed to reach this tier. |
| `requires_paid_minor` | `string` | Paid total, minor units, needed to reach this tier. |

### 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}/usage_tiers/{usage_tier}`; the id is the tier key. |
| `uid` | `string` | `utier_<cell><ulid>`; never reused. Output only. |
| `meta` | `ResourceMeta` | Resource metadata. |
| `rank` | `int32` | Order of tiers; 0 is the base tier. Required. |
| `daily_limit_minor` | `string` | Daily exposure limit in minor units, a decimal string; empty for none. |
| `monthly_limit_minor` | `string` | Monthly exposure limit in minor units, a decimal string; empty for none. |

| `requires_paid_minor` | `string` | Paid total, minor units, needed to reach this tier. |

### 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. |
