# Revoke a delegated signing key

> Revoke a delegated signing key. Revocation is a single signed-retry flow:

1. Call `DELETE /auth/delegated-keys/{id}` with no headers. The response is `202` with a `payloadToSign`, `requestId`, and `expiresAt`.

2. Stamp `payloadToSign` with the session API keypair of a verified credential on the delegated key's Embedded Wallet funding account and retry with `Grid-Wallet-Signature` and `Request-Id` headers. This deletes the delegated user and its API key, after which the key can no longer sign, and the response is `204`.

Deleting the user is the kill switch: it removes the API key the delegated key authenticated with, so signing stops regardless of the policy. The policy is left in place — its consensus references the now-deleted user, so it can never authorize anything (Turnkey user IDs are never reused), and deleting it is unnecessary for correctness or security.

    SignedRequestChallenge:
      title: Signed Request Challenge
      type: object
      required:
        - payloadToSign
        - requestId
        - expiresAt
      description: >-
        Common base for two-step signed-retry challenge responses on Embedded
        Wallet endpoints (credential registration or revocation, session refresh
        or revocation, wallet export, customer email updates, and similar).
        Holds the signing fields shared across every challenge shape; each
        variant composes this base via `allOf` and adds its own resource `id`
        (and `type`, when applicable) with variant-specific description and
        example.
      properties:
        payloadToSign:
          type: string
          description: >-
            Canonical payload for the retry authorization stamp. Build an
            API-key stamp over this exact value with the session API keypair,
            then send the full base64url-encoded stamp in
            `Grid-Wallet-Signature` on the retry that completes the original
            request.
          example: >-
            {"organizationId":"org_2m9F...","parameters":{"userId":"user_2m9F..."},"timestampMs":"1775681700000","type":"ACTIVITY_TYPE_EXAMPLE"}
        requestId:
          type: string
          description: >-
            Grid-issued `Request:<uuid>` identifier for this pending request.
            Echo this value exactly in the `Request-Id` header on the signed
            retry so the server can correlate the retry with the issued
            challenge.
          example: Request:7c4a8d09-ca37-4e3e-9e0d-8c2b3e9a1f21
        expiresAt:
          type: string
          format: date-time
          description: >-
            Timestamp after which this challenge is no longer valid. The signed
            retry must be submitted before this time.
          example: '2026-04-08T15:35:00Z'

        Bearer token authentication for agent-scoped endpoints. The token is the
        `accessToken` returned when redeeming a device code via `POST
        /agents/device-codes/{code}/redeem`. Agent credentials are user-scoped:
        all requests are automatically bound to the agent's associated customer
        and subject to the agent's policy.
