# Export a signed audit bundle for a decided approval

POST

/v1/approvals/{approvalId}/audit-bundle

```sh
curl --request POST \
  --url https://example.com/v1/approvals/2489E9AD-2EE2-8E00-8EC9-32D5F69181C0/audit-bundle \
  --header 'Authorization: Bearer <token>' \
  --header 'Content-Type: application/json' \
  --data '{ "signingKeyId": "example", "includeMessages": false }'
```

Signs the approval, its decision and its evidence with the deployment’s export key, and records the export (an `export-signed` audit event). The same envelope as the other signed exports, so one verifier reads all three; check `publicKey` against `GET /v1/export-signing-keys`. For a decided approval only (approved, rejected, escalated, expired, withdrawn): a pending one is `409 approval-not-decided`. A deployment with no export key answers `404 signing-not-configured`.

## Authorizations

## Parameters

### Path Parameters

**approvalId**

required

string format: uuid

ApprovalId — opaque branded string (a UUID).

### Header Parameters

**Idempotency-Key**

string

\>= 1 characters

Caller-supplied idempotency key, scoped to the caller: the same key from someone else in the tenant is their own request (from 0.1.5). Retries with the same key return the original response byte-identical (per `docs/API-ROUTE-CONVENTIONS.md` §3.1). A retry sent while the first request still runs is answered `409 idempotency-key-in-flight` with `Retry-After`, on a runtime whose store holds keys (from 0.1.5); retry after it, and you get the first request’s answer. An answer that carries a secret (a new API key or public run token, a session token, a generated signing secret) isn’t kept: a retry gets `409 idempotency-key-replay-withheld`, with the first request’s status and when it succeeded (from 0.1.5).

## Request Body

application/json

Body for `POST /v1/approvals/{approvalId}/audit-bundle`, optional: no body signs with the active key. `includeMessages` adds the conversation messages of the approval’s run.

object

**signingKeyId**

Optional: sign with this key, one of `GET /v1/export-signing-keys`. Leave it out to sign with the deployment’s active key. A key the deployment doesn’t sign with is `404 signing-key-not-found`.

string

\>= 1 characters

**includeMessages**

When true, hydrates conversation messages tied to the approval’s run (agent turns pin `runId === conversationId`). Empty array for non-agent runs — field always present when requested.

boolean

## Responses

### 200

Signed audit bundle.

application/json

A decided approval’s signed audit bundle. Body: `{ bundleSchemaVersion, approvalId, tenantId, subjectKind, subjectRef, requiredRole, status, createdAt, decidedAt?, decision, evidence: { guardrailResults?, messages? }, exportedAt }`.

object

**approvalId**

required

string format: uuid

**kind**

Which export this is: `audit-bundle`, `provenance` or `compliance`. Absent from older servers.

string

Allowed value: audit-bundle

**bundle**

required

Base64 of the exact bytes that were signed: the body, as sorted-key JSON with no whitespace. Verify these bytes; nothing needs re-serializing.

string

**bundleSchemaVersion**

required

The body’s version, semver. `2.0.0`: a string like the other exports’ (it was the integer `1`), named `bundleSchemaVersion` in the body too, with `exportedAt` signed once.

string

**algorithm**

required

The signing key’s algorithm. `ecdsa-p256-sha256` signatures are IEEE P1363 `r‖s`. A verifier refuses an algorithm it doesn’t know.

string

Allowed values: ed25519 ecdsa-p256-sha256

**signingKeyId**

required

The key that signed it: one of `GET /v1/export-signing-keys`.

string

**signature**

required

Base64 of the 64-byte signature over the `bundle` bytes: Ed25519’s, or ECDSA P-256’s as IEEE P1363 `r‖s`.

string

**publicKey**

required

The signing key’s public half, PEM SPKI. On its own it only proves the bytes weren’t changed; check it against `GET /v1/export-signing-keys` (or a key you pinned) to know who signed them.

string

**canonicalization**

required

Sorted-key JSON, no whitespace (`canonicalize` in `@kindgi/schema`).

string

Allowed value: sorted-key-json

**exportedAt**

required

When it was signed: the same instant as the signed body’s `exportedAt`.

string format: date-time

##### Example

```json
{
  "kind": "audit-bundle",
  "algorithm": "ed25519",
  "canonicalization": "sorted-key-json"
