Update PIX key

Updates a PIX key’s mutable bindings (account branch/number/type and owner name/trade name) and reports the change to BACEN DICT (signed updateEntry). keyType and ownerTaxId are immutable; an attempt to change them is rejected. The body carries no participant: the wire Participant is always the key’s stored owning participant — the one this call is authorized against — so this verb can never rebind a key to another participant. A key under a BCB judicial block is refused with the EntryBlocked token and HTTP 400, the same answer BACEN gives (DICT 8.4 section 1.1).

Authorizations

Authorization

string

header

required

JWT bearer token issued by the identity provider.

Headers

X-Idempotency

string

required

Idempotency key, max 255 characters

Path Parameters

key

string

required

PIX key value to update (the immutable identifier).

Body

application/json

Mutable key fields (account + owner name/trade name) and the update reason; keyType and ownerTaxId are immutable and rejected if changed.

reason

enum<string>

required

Update reason: USER_REQUESTED (not for EVP keys), BRANCH_TRANSFER, RECONCILIATION, or RFB_VALIDATION. This is the subset BACEN's updateEntry accepts; the wider EntryOperationReason set is not valid on an update.

Available options:

USER_REQUESTED,

BRANCH_TRANSFER,

RECONCILIATION,

RFB_VALIDATION

Example:

"BRANCH_TRANSFER"

accountNumber

string

New account number (account mutable field).

Example:

"9988776"

accountType

string

New account type (account mutable field).

Example:

"CACC"

branch

string

New account branch (account mutable field).

Example:

"0001"

keyType

string

Immutable: supplying a value differing from the stored keyType is rejected.

Example:

"CPF"

ownerName

string

New owner legal name (owner mutable field).

Example:

"João Silva"

ownerTaxId

string

Immutable: supplying a value differing from the stored ownerTaxId is rejected.

Example:

"12345678901"

ownerTradeName

string

New owner trade name (owner mutable field).

Example:

"Silva ME"

Response

Updated PIX key with its mutable fields applied

createdAt

string

required

Key creation timestamp, RFC 3339 (UTC) — OUR row's local timestamp, not BACEN's; see creationDate for the DICT's own binding-creation instant.

Example:

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

string

required

Unique PIX key identifier (UUID) assigned by the service.

Example:

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

keyType

string

required

PIX key type: CPF, CNPJ, EMAIL, PHONE, or EVP (random key).

Example:

"CPF"

keyValue

string

required

PIX key value in its canonical format for the key type.

Example:

"12345678901"

ownerName

string

required

Full legal name of the key owner.

Example:

"João Silva"

ownerTaxId

string

required

Owner tax identifier: 11 digits for a CPF, 14 alphanumeric characters for a CNPJ (IN RFB 2.229/2024).

Example:

"12345678901"

participantISPB

string

required

Owning participant ISPB, the 8-digit BACEN institution identifier.

Example:

"12345678"

status

string

required

Key lifecycle status: ACTIVE, INACTIVE, PENDING_CLAIM, PENDING_BACEN_SYNC, or BLOCKED (judicial block, DICT 8.4 §1.1).

Example:

"ACTIVE"

updatedAt

string

required

Timestamp of the last update to the key, RFC 3339 (UTC).

Example:

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

accountNumber

string

Account number (1..20 digits), omitted for a tuple-less key.

Example:

"9988776"

accountType

enum<string>

BACEN account type (CACC, SVGS, TRAN, SLRY, OTHR), omitted for a tuple-less key.

Available options:

CACC,

SVGS,

TRAN,

SLRY,

OTHR

Example:

"CACC"

bacen

object

BACEN's own operational envelope for its most recent interaction on this key; omitted when no BACEN interaction has ever landed on it.

Show child attributes

branch

string

Account branch (1..4 digits), omitted when unset.

Example:

"0001"

creationDate

string<date-time>

BACEN's own creation instant for this key/account/owner binding, as the DICT answered it; omitted when BACEN's answer carried none.

Example:

"2020-01-15T00:00:00Z"

keyOwnershipDate

string<date-time>

Instant from which the owner has held uninterrupted possession of this key per BACEN; may differ from creationDate after a portability. Omitted when BACEN's answer carried none.

Example:

"2020-01-15T00:00:00Z"

openingDate

string<date-time>

Account opening date, RFC 3339, omitted for a tuple-less key.

Example:

"2020-01-15T00:00:00Z"

ownerTradeName

string

Owner trade name (legal-entity owners), omitted when unset.

Example:

"Silva ME"

ownerType

enum<string>

BACEN's own Person discriminator for the owner, as the DICT published it — not the value the registration declared, which is refused when the two could disagree. Omitted when BACEN's answer carried none.

Available options:

NATURAL_PERSON,

LEGAL_PERSON

Example:

"NATURAL_PERSON"

requestId

string<uuid>

The participant's own identifier for the registration that created this binding, echoed back. It is the value BACEN holds against the vinculo for life, so it is what a DICT support case and a retry are addressed by. Omitted for a key registered before this field existed or adopted by reconciliation — neither had a caller to state one.

Example:

"b2696bf1-0a51-48b0-ab4a-8af2dff440af"
