  update:
    x-rate-limit: 'Bill and interval downloads: 1/minute. All other GET/POST: 1/second. 429 carries Retry-After;
      202 means the payload is being built asynchronously.'

  description: Flag the irreversible consequence of revoking a customer authorization.
  update:
    x-consequence: safety-critical
    x-reversibility: Revocation deletes all collected data and access credentials. Regaining access requires
      a NEW customer authorization; there is no undo.
    x-human-in-the-loop: true
    x-idempotency: none — no Idempotency-Key or replay protection is documented on any write.
