No ledger entry is recorded: issuance takes no balance reservation, so cancellation has nothing to reverse. ## OpenAPI ````yaml /pt/openapi/v3-current/payments.yaml post /v1/boletos/{id}/cancel openapi: 3.1.0 info: description: >- API for the Lerian Payments interface via BTG.

Send it again under the SAME key after a short wait: the key answers this code for at most five minutes after the earlier request arrived. Afterwards the same key answers with the earlier request's stored answer, with 500 PBP-0002 when that answer cannot be replayed, or, when no answer was kept, by running the request. Do not send it under a new key to get past this answer: the earlier request may still take effect.
