  summary: Upload and submit an evidence file against an open chargeback
  description: >-
    Evidence submission is irreversible and asynchronous — it can take up to 24
    hours to complete at the PSP. There is no idempotency key on any step, so a
    timed-out call must be reconciled with a read before it is retried.
