}Authorise payment of an SLB charge
Submits an SLB0002 authorising payment of a charge BACEN raised with an SLB0001, and returns a correlation id plus a PENDING projection. This request IS the authorisation: receiving the notice authorises nothing, so the decision to pay is made here. The amount must equal the charge in full — SLB admits no partial payment (Catálogo v5.13 Vol I) — and is checked against the stored charge before anything reaches the rail. A charge already settled or withdrawn is refused. When the deployment configures an alçada band covering the amount, the message parks in PENDING_APPROVAL and is not transmitted until the required signatures are collected.

}Authorizations
JWT bearer token issued by the identity provider.
Headers
Idempotency key. Required on every mutation.
Idempotency key TTL in seconds.
Body
application/json
The charge's FULL value in decimal reais. SLB admits no partial payment (Catálogo v5.13 Vol I), so anything other than the notified amount is refused.
Pattern:
^[1-9][0-9]{0,15}\.[0-9]{2}$|^0\.(0[1-9]|[1-9][0-9])$Example:
"1500.00"
Control number (NumCtrlSLB) of the charge being paid, as the SLB0001 notice carried it. Rule RSLB0002 makes it mandatory on the wire: a payment that does not name the charge it pays is not a payment of that charge.
Required string length:
1 - 20Example:
"SLB20260915000000001"
Optional processing preference (NivelPref).
Maximum string length:
4Example:
"0001"
Response
Accepted
Request-scoped correlation identifier echoing X-Request-ID.
Example:
"req-7a3f9c2e"
Correlation id (the outbound NUOp). The answer leg is correlated to it.
Example:
"46026562202609150000001"
The SLB wire code that was submitted.
Example:
"SLB0002"
BACEN business date (DtMovto) stamped on the frame, derived server-side.
Example:
"2026-09-15"
This participant's own control number for the message — the handle BACEN quotes back on the answer.
Example:
"20260915000000000001"
SUBMITTED when the message was queued for the rail, PENDING_APPROVAL when the configured alçada band parked it awaiting signatures.
Example:
"SUBMITTED"
RFC3339 UTC timestamp the message was submitted.
Example:
"2026-09-15T12:00:00Z"
