Creates a webhook endpoint.

- **Path** `POST https://api.sylphx.com/v1/orgs/acme/projects/shop/envs/production/webhook_endpoints`
- **Scope** `events:write`
- **Effect** `write` — a successful call changes state.
- **Collection** [webhook_endpoints](/docs/api/webhook_endpoints)
- **Query** `webhook_endpoint_id`, `validate_only`

## Request

| Field | Type | What it is |
| --- | --- | --- |
| `parent` | `string` | The parent to create in. Required. |
| `webhook_endpoint_id` | `string` | The webhook endpoint id, the final name segment; the server assigns one when empty. |
| `webhook_endpoint` | `WebhookEndpoint` | The webhook endpoint to create; only caller-writable fields are read. Required. |
| `validate_only` | `bool` | Validate and return the result without writing anything. |

### WebhookEndpoint

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

### WebhookEndpointSpec

| Field | Type | What it is |
| --- | --- | --- |
| `uri` | `string` | The HTTPS URI deliveries are POSTed to; its host resolves to a public address. Required. |
| `disabled` | `bool` | Stop delivering; deliveries queue until enabled. |
| `max_concurrent_deliveries` | `int32` | At most this many deliveries in flight; default 10. |
| `event_types` | `string[]` | Which event types the endpoint receives: an exact type (`order.paid`), a prefix ending in `.*` (`order.*`), or `*` for every type; default `["*"]`. |
| `rate_limit_per_second` | `int32` | At most this many attempts start per second; 0 is no limit. Deliveries over the limit wait their turn; none is dropped. |

## Response

| Field | Type | What it is |
| --- | --- | --- |
| `name` | `string` | `orgs/{org}/projects/{project}/envs/{env}/webhook_endpoints/{webhook_endpoint}`. |
| `uid` | `string` | `whe_<cell><ulid>`; never reused. Output only. |
| `meta` | `ResourceMeta` | Resource metadata. |
| `spec` | `WebhookEndpointSpec` | Desired state. Required. |
| `status` | `WebhookEndpointStatus` | Observed state. Output only. |

### 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. |

### WebhookEndpointSpec

| Field | Type | What it is |
| --- | --- | --- |
| `uri` | `string` | The HTTPS URI deliveries are POSTed to; its host resolves to a public address. Required. |
| `disabled` | `bool` | Stop delivering; deliveries queue until enabled. |
| `max_concurrent_deliveries` | `int32` | At most this many deliveries in flight; default 10. |

| `state` | `WebhookEndpointState` | Whether Events is delivering. Output only. One of `enabled`, `disabled`, `failing_disabled`. |
| `disable_reason` | `string` | Why Events disabled the endpoint, when it did. Output only. |
| `last_success_time` | `timestamp` | The last 2xx answer. Output only. |
| `consecutive_failure_count` | `int32` | Consecutive failed delivery attempts since the last 2xx. Output only. |
| `signing_secret` | `string` | The Standard Webhooks signing secret (`whsec_…`). Set only in the answer of CreateWebhookEndpoint and RotateWebhookEndpointSecret; every other read leaves it empty, and Events never shows it again. Output only. Never returned again. |
| `previous_secret_expire_time` | `timestamp` | After a rotation, deliveries carry a second signature with the previous secret until this time. Output only. |
