  update:
    x-authentication: API key in the X-API-Key header, issued per application registered at https://openbanking.api.tietoevry.com.
      Live access additionally requires eIDAS QWAC/QSealC client certificates. See authentication/tietoevry-authentication.yml.
    x-idempotency: NOT SUPPORTED. X-Request-ID is a correlation identifier only; the provider documents no replay
      guarantee, no retention window and no Idempotency-Key header. Do not retry a write on timeout.
    x-error-format: 'Berlin Group envelope: { transactionStatus, tppMessages[{category,code,text}], psuMessage }.
      Not RFC 9457. See errors/tietoevry-problem-types.yml.'
    x-rate-limits: No platform rate limit is published. 429 fires when the consent frequencyPerDay quota set by
      the client is exhausted; no Retry-After or RateLimit-* header is returned. See rate-limits/tietoevry-rate-limits.yml.
    x-reversibility: Reversal operations exist (cancel / refund / reject / chargeback / recall / delete-consent)
      but NO time window is published for any of them. See conventions/tietoevry-conventions.yml.
    x-lifecycle: No deprecation or sunset policy, no status page, no dated changelog. See lifecycle/tietoevry-lifecycle.yml.
