}Ask for the compulsory period calendar or read a filing back
Submits one of the two reporting consultas: the period calendar (RCO0001), which publishes both windows and both deadlines, or the filing read-back (RCO0003). A read-back’s reference date must fall inside the period being queried (RRCO0002), which is checked before the frame is built. The answer arrives asynchronously and lands on the compulsory period row.

}Autorizaciones
JWT bearer token issued by the identity provider.
Encabezados
Idempotency key. Required on every mutation — a consulta is an emission, not a read of this rail.
Idempotency key TTL in seconds.
Cuerpo
application/json
CodRCO — required on both.
Ejemplo:
"9"
periodCalendar asks which periods are open and when they close (RCO0001); filingReadBack reads a statement already filed (RCO0003).
Opciones disponibles:
periodCalendar, filingReadBack Ejemplo:
"periodCalendar"
DtRef — the day being asked about. On a filing read-back it must fall inside the declared period (RRCO0002).
Ejemplo:
"2026-09-03"
GrupoIFRCO — optional, and read only by the period calendar.
End of that period. Same treatment.
Start of the calculation period a read-back is scoped to. Required for filingReadBack; it does NOT reach the wire — it is what makes the reference-date rule checkable before the round trip is spent.
Respuesta
Accepted
BACEN message code actually sent.
Ejemplo:
"RCO0002"
Outbound operation number.
Pattern:
^[0-9A-Z]{8}[0-9]{15}$Ejemplo:
"12345678202609150000001"
Participant control number — the handle the answer echoes.
Emission state of the frame. The ANSWER arrives asynchronously.
Ejemplo:
"SUBMITTED"
When the frame was submitted.
Request-scoped correlation identifier echoing X-Request-ID.
