# Submit a decision on an approval

POST

/v1/approvals/{approvalId}/complete

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

Records the decision (`HitlBinding.submitReview`). When the approval carries a `waitTokenId` and the decision is `approve` or `reject`, also completes the waitpoint so the suspended run resumes, with `{ decided, rationale?, decidedBy, approvalId }`: the run’s journal records who decided which approval (`decidedBy` is `user:<userId>`).

## Authorizations

- **[bearerAuth](https://docs.kindgi.com/v0.1.8/reference/api.md#bearerauth)**

## 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 Bodyrequired

application/json

object

**decision**

required

string

Allowed values: approve reject escalate withdraw

**rationale**

string

**value**

Payload passed to the run waitpoint (`RunBinding.completeToken`) when the approval is linked to a suspended run and the decision is `approve` or `reject`. Refused (400 `bad-input`) for an agent’s tool-call or session gate (`tool-call:pending`, `agent-turn:session-hitl-gate`): those resume on the decision alone.

## Responses

### 200

Decision recorded.

application/json

A recorded decision, and what it did to the run waiting on the approval. `runStatus` is the run’s status when the decision couldn’t resolve its waitpoint because the run had already ended (e.g. `cancelled` after the decision was recorded); the decision stands.
