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 A charge already settled or withdrawn is refused.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. Idempotent — the X-Idempotency key lives with the payment: the same key and parsed request (member order and whitespace do not count; any other difference, such as number spelling, null for an absent field, or an unknown member, is another request) answer the stored payment with X-Idempotency-Replayed: true, also after X-TTL has dropped the cached response, and the same key with another request answers 422.

Authorizations

Authorization

string

header

required

JWT bearer token issued by the identity provider.

Headers

X-Idempotency

string

required

Idempotency key. Required on every mutation.

X-TTL

string

Seconds the cached response is kept; it may only shorten IDEMPOTENCY_DEFAULT_TTL_SEC. The key itself lives with the payment.

Body

application/json

amount

string

required

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"

controlNumberSLB

string

required

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 - 20

Example:

"SLB20260915000000001"

preferenceLevel

string

Optional processing preference (NivelPref).

Maximum string length: 4

Example:

"0001"

Response

Accepted

correlationId

string

required

Request-scoped correlation identifier echoing X-Request-ID.

Example:

"req-7a3f9c2e"

string

required

Correlation id (the outbound NUOp). The answer leg is correlated to it.

Example:

"46026562202609150000001"

messageType

string

required

The SLB wire code that was submitted.

Example:

"SLB0002"

movementDate

string

required

BACEN business date (DtMovto) stamped on the frame, derived server-side.

Example:

"2026-09-15"

numCtrlPart

string

required

This participant's own control number for the message — the handle BACEN quotes back on the answer.

Example:

"20260915000000000001"

status

string

required

SUBMITTED when the message was queued for the rail, PENDING_APPROVAL when the configured alçada band parked it awaiting signatures.

Example:

"SUBMITTED"

submittedAt

string

required

RFC3339 UTC timestamp the message was submitted.

Example:

"2026-09-15T12:00:00Z"
