> **This method is not served on the public API.** `api.sylphx.com` does not route this call: its backend is not deployed behind the public API, or does not implement the call. This page documents the contract. It is kept out of the sidebar and of search engines.

Creates a trust policy.

**Not available yet.** Sylphx Broker is declared in the registry but no backend serves it: every call answers `501` with the problem code `UNIMPLEMENTED`.

- **Path** `POST https://api.sylphx.com/v1/orgs/acme/trust_policies`
- **Scope** `broker:admin`
- **Effect** `write` — a successful call changes state.
- **Collection** [trust_policies](/docs/api/trust_policies)
- **Query** `trust_policy_id`, `validate_only`

## Request

| Field | Type | What it is |
| --- | --- | --- |
| `parent` | `string` | The org to create in. Required. |
| `trust_policy` | `TrustPolicy` | The trust policy to create; only spec and caller-writable metadata are read. Required. |
| `trust_policy_id` | `string` | The id of the new trust policy, `^[a-z]([a-z0-9_-]{0,61}[a-z0-9])?$`; the server assigns one when empty. |
| `validate_only` | `bool` | Validate and return the result without writing anything. |

### TrustPolicy

| Field | Type | What it is |
| --- | --- | --- |
| `name` | `string` | `orgs/{org}/trust_policies/{trust_policy}`. |
| `meta` | `ResourceMeta` | Resource metadata. |
| `spec` | `TrustPolicySpec` | 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. |

### TrustPolicySpec

| Field | Type | What it is |
| --- | --- | --- |
| `connection` | `string` | The Connection credentials are issued on. Required. |
| `subjects` | `string[]` | The identities allowed to exchange: SPIFFE ids (`spiffe://<trust-domain>/cell/<cell>/role/<role>`, `*` matching one segment) or Sylphx Access principal names. The cell segment is never stripped. Required. |
| `permissions` | `map<string, string>` | The most a credential may carry, in the provider's permission names, for example `{"contents": "read", "checks": "write"}`. Required. |
| `repositories` | `string[]` | The most repositories a credential may cover; empty means every repository the Connection covers. |
| `credential_kind` | `CredentialKind` | What the credential service issues. Required. One of `access_token`, `runner_registration`. |
| `max_ttl` | `duration` | The longest a credential lives; default and maximum 1 hour. |

## Response

| Field | Type | What it is |
| --- | --- | --- |
| `name` | `string` | `orgs/{org}/trust_policies/{trust_policy}`. |
| `uid` | `string` | `trp_<cell><ulid>`. Output only. |
| `meta` | `ResourceMeta` | Resource metadata. |
| `spec` | `TrustPolicySpec` | 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. |

### TrustPolicySpec

| Field | Type | What it is |
| --- | --- | --- |
| `connection` | `string` | The Connection credentials are issued on. Required. |

| --- | --- | --- |
| `observed_generation` | `int64` | The generation this status was computed from. Output only. |
| `conditions` | `Condition[]` | Ready, Reconciling, Stalled. Ready is FALSE with reason `CapabilityMissing` when the Connection lacks a permission the policy names. Output only. |

### Condition

| Field | Type | What it is |
| --- | --- | --- |
| `type` | `string` | The condition type, for example `Ready`. |
| `status` | `ConditionStatus` | Whether the condition holds. One of `true`, `false`, `unknown`. |
