# Rotate a signing secret

> Issue a fresh `whsec_…` signing secret, invalidating the old one immediately. Returns the new secret EXACTLY ONCE. Requires a key carrying the wildcard `*` scope. Request body is ignored.



## OpenAPI

````yaml /openapi-v1.yaml post /v1/webhooks/{subscriptionId}/rotate-secret
openapi: 3.1.0
info:
  title: EnfinitOS API
  version: v1.0
  description: >-
    The governed-execution `/v1` developer API for EnfinitOS — rights, delivery,
    proof, and settlement.


    Use this API to register the legal **bases** a right rests on, **issue** and
    lifecycle-manage rights across delivery substrates (DOOH, CTV, spatial/AR,
    mobile, audio, and more), negotiate **offers**, raise and resolve
    **challenges**, observe constraint-gated **deliveries**, seal signed **proof
    packs**, read **metering** + **settlement** projections, configure
    settlement **rules** and **counterparties**, fulfil GDPR **compliance**
    requests, and subscribe to **webhooks**.


    Every state-changing action is appended to an immutable, signable audit log;
    delivery and proof artefacts are Ed25519-signed so a downstream auditor can
    verify them offline.


    ## Response envelope

    Every response wraps its payload in a canonical envelope.


    Success (HTTP 200):

    ```json { "ok": true, "data": { ... }, "contractVersion": "v1.0" } ```


    Error (4xx / 5xx):

    ```json { "ok": false, "error": "VALIDATION_FAILED", "message": "human
    text", "contractVersion": "v1.0" } ```

    Some error responses carry additional context fields alongside `error` and
    `message` (for example `field`, `validationErrors`, `requiredScopes`,
    `keyScopes`).


    ## Authentication

    All endpoints except `GET /v1` and `GET /v1/healthz` require an API key sent
    as `Authorization: Bearer <api-key>`. Keys carry a set of named scopes; each
    operation documents the scope it requires. A key carrying the `*` wildcard
    scope passes every scope check.

    Pre-launch, sandbox keys are issued through the apply flow: request access
    at `/apply`, receive an activation email on approval, and exchange it for a
    `/v1` sandbox key in the integration playground at `/developers/playground`.
    Self-service key issuance from the developer dashboard at
    `/developers/dashboard` lands at the April 2027 production launch.


    ## Identifiers

    Resource ids are prefixed: bases `bas_…`, rights `rgh_…`, offers `ofr_…`
    (passed as `rightId`/`offerId`), settlement rules `rule_…`, counterparties
    `cp_…`, webhook subscriptions, and webhook deliveries `dlv_…`. All
    timestamps are ISO-8601 strings.
