# Approve a reviewed Application plan as a person

> Records one server-issued immutable person approval receipt bound to one exact plan atom, the plan id/fingerprint, the requirement-set digest, and the reviewed provenance. The request names one server-returned atom id and nothing else; the server reads every authority fact. Idempotent for the same plan, atom, person, and Idempotency-Key. The 128th approval event exhausts the plan's approval-event capacity and immediately expires the plan (§7.6).

Checkfu support posture: alpha; hosted. Required evidence journey: blueprint-authority. Deployment-specific readiness and the latest proven release are available from GET /v1/support/capabilities.

    Authentication is declared per operation: API-key, runtime, or connector
    bearer; Automation signature; or credential-free pairing redemption. Every
    general Checkfu REST request requires the dated `Checkfu-Version` header
    (one of: 2026-08-31); the three MCP JSON-RPC transports use
    `MCP-Protocol-Version`, A2A uses `A2A-Version`, and the provider OAuth
    callback carries neither Checkfu header. API keys resolve one Workspace
    without a request selector; authenticated responses identify it with
    `Checkfu-Workspace-Id`.
