# Reject an authority grant change

> Rejects an authority grant change.



## OpenAPI

openapi: 3.1.0
info:
  title: Parmana API
  version: 1.0.0
  description: >
    Parmana sits between an AI agent and the systems it acts on. An agent sends
    a Business Transaction: who

    authorized it, what action it wants, and the facts that justify it. Parmana
    evaluates the policy bound to

    the action, checks any signed human approval the policy requires, releases
    the action to the connector

    only if the policy approves, and returns a signed Execution Trust Record
    anyone can verify.


    **Authentication.** Send `Authorization: Bearer <key>` on every request. The
    only routes that need no key

    are the probes, the documents and the independent verification routes: `GET
    /health`, `GET /ready`,

    `GET /openapi.yaml`, `GET /openapi.json`, `GET /api-manifest.json`, `GET
    /documentation`,

    `GET /reference`, `GET /parmana-handbook.pdf`, `GET
    /handbook/download-leads`,

    `POST /handbook/download-leads`, `POST /refusal/verify`, `POST
    /execution-intents/verify`,

    `POST /audit/verify`, `GET /keys/{keyId}` and `GET /.well-known/jwks.json`.
    A missing or unknown key

    returns `401` before anything else runs. The server holds only a hash of
    each key. See

    [Authentication](/api-reference/authentication).


    **Two kinds of key.** An agent or service key may invoke only the
    capabilities listed on it. A human key

    (`credentialHolderType: USER`) is required for governance: proposing and
    approving policies, approvers

    and external connectors, and repairing Execution Intents. Approving or
    rejecting a change also needs a

    step up authorization signed with the checker's own step up key, and the
    checker must not be the

    person who proposed it.


    **Ownership.** Every lookup by `businessTransactionId` is scoped to the key
    that submitted the

    transaction. A transaction submitted by another key returns the same `404`
    as one that does not exist.


    **Try it live.** The first server below is the public sandbox,
    `https://parmana-sandbox.vercel.app`: the same

    code as production with its own database, keys and demo approver, whose one
    action, `sandbox:receipt`,

    acts on nothing. Every "Try it" panel calls it with the published demo key
    prefilled. The demo key may

    invoke only `sandbox:receipt`, so other capabilities return `403` and
    governance routes return

    `403 NON_HUMAN_CALLER_DENIED`. Everything sent to the sandbox is visible to
    every visitor. See

    [Playground](/playground). Production needs a key issued by its operator.


    **Start here:** the [Playground](/playground) (no install), the
    [Quickstart](/quickstart), then [Integrate Parmana](/agents/integrate) for
    agents

    and [Connect any external system](/guides/connect-any-external-system) for
    your own endpoint.
