Register the direct participant this rail operates as

Establishes the institution this rail IS at the SPI: the ACTIVE DIRECT participant that anchors the closed set of participants whose arriving Pix settle here (its own accounts, plus every indirect it is BACEN-confirmed liquidante for). Admin-only, and at most one may be ACTIVE. There is no reda flow for a direct participant — the SPI refuses a reda.014/reda.031 naming one (reda.016 error DIR1) — so nothing external confirms this act and it is not client-callable.

Authorizations

Authorization

string

header

required

JWT bearer token issued by the identity provider.

Headers

X-Idempotency

string

required

Idempotency key, max 255 characters

Body

application/json

contactEmail

string

required

Lower-case e-mail BACEN uses to reach this participant about a funds-recovery case (DICT 2.12.1 Email pattern). The address must be lower-case: an upper-case one is refused, never rewritten. The service checks the format, not the published schema, so a refusal never echoes the submitted value back.

Example:

"med@bancoexemplo.com.br"

contactPhone

string

required

E.164 phone BACEN uses to reach this participant about a funds-recovery case (DICT 2.12.1 Phone pattern: +, then 2 to 15 digits). The service checks the format, not the published schema, so a refusal never echoes the submitted value back.

Example:

"+5511999998888"

ispb

string

required

ISPB of the institution this rail operates as, exactly 8 digits or uppercase letters.

Pattern: ^[0-9A-Z]{8}$

Example:

"12345678"

name

string

required

Legal name of the institution. The 256-character bound is Lerian's own — it is what participants.name stores — not a BACEN limit.

Required string length: 1 - 256

Example:

"Banco Exemplo S.A."

Response

Created

contactEmail

string

required

Registered regulator-facing e-mail; travels on every MED 2.0 funds recovery opened for this participant.

Example:

"med@bancoexemplo.com.br"

contactPhone

string

required

Registered regulator-facing phone; travels on every MED 2.0 funds recovery opened for this participant.

Example:

"+5511999998888"

createdAt

string

required

UTC timestamp when the participant was created, RFC 3339 format.

Example:

"2025-03-07T14:30:00Z"

string

required

Server-assigned UUID of the participant.

Example:

"550e8400-e29b-41d4-a716-446655440000"

ispb

string

required

ISPB of the participant, exactly 8 digits or uppercase letters.

Example:

"12345678"

name

string

required

Legal name of the participant institution.

Example:

"Banco Exemplo S.A."

status

string

required

Lifecycle state of the participant: ACTIVE, SUSPENDED, OFFBOARDED, PENDING (indirect reda.014 in flight), REGISTRATION_REJECTED (reda.016 REJT), or OFFBOARD_PENDING (reda.031 in flight).

Example:

"ACTIVE"

type

string

required

Connection type: DIRECT (connects directly to BACEN) or INDIRECT (routes through a sponsor).

Example:

"DIRECT"

updatedAt

string

required

UTC timestamp of the last update to the participant, RFC 3339 format.

Example:

"2025-03-07T14:30:00Z"

config

object

Quota and routing configuration; present only for indirect participants.

Show child attributes

ISPB of the sponsoring participant (8 digits or uppercase letters); present only for INDIRECT participants.

Example:

""
