# Register a reviewer

POST

/v1/approvals/reviewers

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

Idempotent by `(tenantId, userId)`. Re-registering rotates role/displayName rather than inserting a duplicate row.

## Authorizations

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

## Parameters

### 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
