Invalidate a person's transaction PIN
Does not delete the row. Sets a hard lock (423 pin_locked on
cashout) and keeps the person enrolled, so
POST /v1/people/pin/reset-request still works. Does not ask for the
current PIN. Hosted reset does not block this call.
Authentication
Bearer authentication of the form Bearer <token>, where token is your auth token.
Headers
Optional client-generated idempotency token (recommended for safe retries).
Unix seconds. Required on the signed host; tolerance is 300s either way (403 request_timestamp_skew).
Lowercase hex SHA-256 of the body. An empty body hashes the empty string, so the header is always present. Mismatch returns 400 body_hash_mismatch.
Detached JWS (<protected>..<signature>, ES256 or PS256) over METHOD\nPATH?QUERY\nTIMESTAMP\nIDEMPOTENCY_KEY_OR_EMPTY\nX_CONTENT_SHA256.
